In Dangerous Liaisons, Klaus sends Caroline a dress and invites her to the ball, his mother is throwing. Caroline refuses, but when Rebekah invites Matt, she changes her decision. She tries to find a dress other than the one Klaus gives her but can't so wears the dress and the bracelet, he gave to her in Our Town. When Caroline arrives at the ball Klaus immediately notices her, he greets her, but she rushes to find a drink instead. Klaus dances with her during the Waltz; during that time she is focusing on Matt and Rebekah, while giving an excuse as to why she wore his gown. Klaus asked Caroline why she wore his bracelet; before she can answer he compliments her dancing abilities. Later, Klaus approaches Caroline outside while she is watching a horse; they discuss their relationship between their fathers. She then reminds him she is a good person, and people like good people unlike him, and then she walks away. Later he shows her his art, and revealing her bracelet once belonged to a Princess "Almost as beautiful as her." Caroline is surprised the drawings are Klaus'. HE then offers to take her to see the beauties of the world; Rome, Paris, Tokyo, which makes them smile. Caroline asked what it’s liked to get everything you want which then turns into her confronting him saying you can’t buy people to make them like you. Then he asked her to leave. Later, when she’s at home she notices a box on her bead inside is a drawing of her and a horse, and at the bottom it says "thanks for being honest." In All My Children, Damon is trying to keep Elena safe, but needs to distract Klaus so Alaric could kill Kol. The distraction just happened to be Caroline, she walks into The Grill, Kol called her a "tasty little thing" which leads Klaus to say "Say another word, and I'll tear out your liver." Klaus asked Caroline if she would like a drink, she rejects him, acting upset, Klaus commented "Isn't she stunning?" and to his response Kol says "She certainly looks good walking away from you." Klaus finishes his drink, and then follows Caroline outside. He calls out to her and she responds "Are you serious? Take a hint." Klaus then apologizes for their little argument. Caroline tells him to leave her alone, but he still doesn't go away he say "Take a chance, talk to me, get to know me. I dare you." He smiles, she agrees she asks him "What do you want to talk about?" which her relies "I want to talk about you. Your hopes, your dreams, everything you want in life." She responds she can’t be seduced by him, and he responds that’s why he likes her. Klaus feels a puncture in his heart; he gets in a rage, asking her what she did. She says she didn’t do anything; he then grabs her asking her again, she responds “I didn’t do anything, stop it.” Now in pain. Klaus lets her go, realizing what happened: Kol was stabbed. At the end of the episode Klaus burns the sketches he drew of Caroline, trying to burn his feeling for her as well.

In Heart of Darkness, it's revealed that Caroline has kept the drawing Klaus gave to her in Dangerous Liaisons. When Tyler asks her about it she doesn't respond. In Do Not Go Gentle, Klaus asks Caroline to dance with him. At first she rejects but then Tyler agrees so she does. While they dance he revels he is leaving the next day. Caroline responds with anything but relief. He says he would invite her to go with him but she's not ready yet. He tells her he'll show her "what the world has to offer" if she shows up on his doorstep one day. Caroline scoffs, hurting Klaus's feelings. Before he leaves the dance he promises Caroline she will get bored with her "small town boy" and her "small town life" that it won’t be enough for her. "Caroline watches Klaus leave. In Before Sunset, Klaus saves Caroline from Alaric, he tells her to go lock herself in her house, while he go saves the other. Caroline nods and thanks him. He looks at her, touched then runs away. Caroline looks back at the way he went, then went home. Later she is at Elena's house celebrating their "victory party" in celebration of a "Klaus free life" Tyler(Klaus, in Tylers body), and Caroline in The Departed In The Departed, Caroline goes to find Tyler, crying because Klaus is supposed dead, which means Tyler will die. Although, Klaus is really in Tyler's body unknown to Caroline.While Caroline is crying Tyler is sating "You're strong and you have a beautiful future ahead of you." They then kiss, which is Caroline and Klaus' first kiss, unknown to Caroline. Klaus then pretends to start dying, and tells Caroline to leave.

Season 4
In Growing Pains, when Caroline and Rebekah get kidnapped, Tyler(Klaus) comes to save Caroline but not Rebekah. Caroline is happy to see Tyler is still alive, they begin to make out when Tyler(Klaus) calls her "love" which makes Caroline realize it Klaus not Tyler. She says he's disgusting and she has to  sanitize her mouth. They find Bonnie to do the reverse spell, when she refuses, he starts ripping out Tyler's heart, which make Bonnie do the spell.

In The Rager, Klaus visits Tyler's house, where he meets Hayley, a werewolf from Tyler's past. Klaus thinks somethings going on between them. Tyler walks into his dad's old office Klaus is siting in his chair. Klaus tells Tyler he thinks while they were gone he and Hayley shared a passionate moment, and then remarks "Caroline has no idea." which gets Tyler upset. In We all Go a Little Mad Sometimes Caroline arrives at Tyler's house while Klaus and Hayley are there. They "fake break up"  and Klaus believes it. Later, to distract Klaus, Caroline goes to The Grill to confront Klaus. She tells him he wants him to give Elena back, Klaus replies she needs his help. He doesn't want to bother Caroline with the details because she has to much to deal with already-referring to the "fake breakup". He then offers her a drink and she accepts, keeping Klaus occupied. Meanwhile, Elena runs away from Stefan, Caroline confesses to trying to distract Klaus, which makes Klaus mad. Klaus gets up to leave, she calls back for him when he says "Caroline your beautiful but if you don't stop talking I will kill you." She then tells him she knows how to stop Elena's hallucinations. It catches his attention and he gives her ten seconds. It is later revealed that Caroline convinced Klaus to sacrifice one of his Hybrids to stop Elena's hallucinations by agreeing to go on a date with him. In My Brother's Keeper, Caroline is organizing Miss Mystic Falls Pageant, when Klaus shows up to get the date she promised fulfilled. She says Klaus can be her date for the Miss Mystic Falls Pageant. She tells Klaus to meet her the next day at the Lockwood Mansion, and warns him not to think to buy her anything so much as a corsage- referring to the dress he got her in season 3. The next day when Klaus arrives he asked her hoe he looks to which she replies "You're...perfect." Later Caroline and Elena are arguing when Klaus interrupt stating "You're making  scene." Then Klaus suggest they get a drink. They talk about the cyber-bond.Klaus pulls out a paper from the previous year, it is Caroline's Miss mystic Falls application and taunts her by reading some of her responses out loud, they both end up laughing. Tyler Listens in on their conversation and hears Klaus tell Caroline there was one time when he did think about being human.

In Come All Ye Faithful, Caroline acts as yet another distraction for Klaus so Stefan can search for Alexander's sword that Klaus has. Klaus finds her at The Grill studying his painting. Caroline says she needs a drink to which Klaus replies hats there thing and then Caroline replies they don't have a thing. Later Caroline and Stefan feel bad for betraying Klaus.

In A View to a Kill, Klaus wonders how Elena is able to overlook the horrible things Damon's done. He asked if he has compelled her, or if Elena is a little mad, or if its just the sire bond. He then asks what he says to her. This peeks Damon's interest. Damon asked if this has to do with Caroline. In Into the Wild, Caroline stops by Elena's house, where Klaus is locked up. Caroline tries to get Tyler to leave, but refuses to watch Klaus in his misery. Klaus tries to get Caroline to call Bonnie to let him out but Caroline refuses and says she would never help him. He then points out all the good things hes done, but then Caroline replies with the bad things hes done, that his charms couldn't make him forget about all the bad things. Caroline refuses to talk about him anymore saying he's not worth the calories she burns talking to him. This causes Klaus to go into a rage and stakes her with a lamp post, then he bites her, surprising Caroline. Later Caroline is panicking over what Klaus has done. Tyler tries to calm Caroline, then confronts Klaus reminding him that Caroline will die if he doesn't giver her his blood. Klaus tells Tyler to beg to save Caroline's life,he refuses, but quickly gives in and begs Klaus. Klaus then says that it would be pathetic of him to help her because once he did  he would kill him. Tyler offer to be Klaus' slave if he heals Caroline. Klaus refuses. Caroline, hurt, ask Tyler to help her leave the room, unable to look at Klaus. The next day, Caroline's health grows worse, Tyler brings her back downstairs, so Klaus can see her. They do this trying to play off Klaus' feelings toward Caroline, that the sight of her dying will make him want to save her. He tells her that her death is nothing personal, but a means to gain power over Tyler. Later, Caroline who is almost at death lies on the couch, Klaus refusing to look at her, Caroline warns her again that if he doesn't giver her his blood she will die. Klaus accepts it bitterly, knowing that Tyler will learn his lesson. Caroline asks him why he does all the evil things, to which her replies he's pure evil. Caroline argues that he only acts like this because he is hurt. This captures Klaus' attention. She continues saying that anyone who is capable of hurting is capable of being human. He moves closer wondering why she thinks that. She says shes seen his humanity, and she wishes she could forget all of the horrible things he's done. He then asks her id she could forget, she doesn't answer but says she knows he's in love with her, and anyone capable of being in love is capable of being saved. Her death not far off, she adds she guesses she'll never know. At that point Klaus' bite takes full effect on Caroline's body. Panicked, Klaus repeats her name a couple times, when she doesn't respond he bites his wrist and offers it to her, she responds to his blood holding his arm while she drinks as he strokes her hair.

In Down the Rabbit Hole, Elena updates Caroline on whats going on. They asked Caroline to get Klaus' sword so they could translate Jeremy's tattoos aka the photos Bonnie took and send them a map and directions. Klaus wouldn't hand the sword over, After getting off the phone, Klaus asked Caroline if she needs any help which she said no to. Caroline and Tyler found the sword in Klaus' attic. The handle is a cryptex

"I've seen the Da Vinci Code," -Caroline

so they basically had to twist parts and read Aramaic, which of course Klaus knew. There's only one dose of the cure. Klaus, who'd wisely, decided that he could help Caroline and Tyler read the cryptex and keeps that important information to himself, shouted it out to Rebekah when Caroline phoned her to say they were emailing the translation and directions. Later, Tyler leaves town, because Klaus would start coming after him. Caroline begged him to let her try to fix things with Klaus because she didn't want to say goodbye to him again. Caroline tried to convince Klaus that he didn't have to forgive Tyler, he just needed to let him live far away from Mystic Falls. Klaus repelled, and it turned off into a conversation about whether Caroline would take the cure if she had the chance. Klaus knew she wouldn't, she’s like him: She likes being strong, ageless, and fearless. Caroline turned it around on Klaus: If they’re so much alike, then he should show Tyler the mercy she’d show Klaus. For a moment, it appeared she’d gotten through to him. We heard the epic love theme in the background. But the only mercy Klaus would show Tyler, for Caroline’s sake, was a head start. But that’s better than nothing right? Caroline said a tearful goodbye to Tyler. “We’re immortal,” he reminded her. “This isn’t goodbye, this is until we find a way,” he said. Also all together heartwarming and heartbreaking at the same time was her response: She told Tyler if they couldn't find a way, he had to promise he’d live a full, happy life without her and never think of her again. For her sake, he said it. They kissed. He slowly walked away. And Caroline sat there crying. Klaus walked out of Elena's house. He told Caroline he assumed he was free because something had happened to Bonnie. He also said he’d never hurt Caroline, and that he’d shown kindness, forgiveness, and pity FOR HER!!!

In Bring It On, Elena told Caroline that if she turned her humanity off she wouldn't have to feel guilty about the dirty thoughts she has about Klaus. In Because the Night, Caroline is at the Salvatores' home cleaning up after Elena's party from the night before. Still upset by what happened the night before, she is seen drinking from a leftover beer cup as Klaus walks in. He notes what she is trying to do before she asks what he's doing here. Klaus pities with her before joking about drinking something more sanitary. In an act of defiance, Caroline takes a sip from another cup before discarding it in the trash. Klaus reproaches her attempt with sarcasm and Caroline responds by wondering why he's not out searching for Tyler, suggesting that perhaps there are still some “hopes and dreams in Mystic Falls that he would like to crush before he goes.” Klaus asks if she knows where Tyler is to which Caroline responds by informing Klaus that he's not with her and has given the deed to his house to Matt. Klaus steps forward and points out that it was Tyler's intent to kill him and that it's not fair of Caroline to hate him for driving him away in response. Caroline disagrees, suggesting that she does hate him before telling him to go away. Stefan interrupts at this point, informing Caroline that Stefan asked Klaus to come; that they could use his help because he thinks Silas is in Mystic Falls. Still in the Salvatore house, Klaus helps himself to a drink as he questions Stefan's assumption that Silas is back in town. He suggests that it is Elena who is responsible for the missing hospital blood. Stefan denies Elena's involvement. Assuming that it is Silas, Klaus ponders why he should care about Silas being in Mystic Falls. Stefan explains that Silas wants to die to be reunited with his true love, but because he's supernatural if he dies he will be stuck on the supernatural other side. However, if Silas destroys the other side altogether, he can take the cure, die, and pass on, but that means the dead supernatural on the other side will be returned to this side. Caroline underscores this by pointing out that every werewolf, witch, and vampire - including the many that Klaus has killed will return, wondering if Klaus cares yet. Klaus concedes that his interest has been piqued. He asks Stefan how they can stop Silas. From Bonnie, Stefan has learned that Silas needs three massacres to do the spell, noting that two have already been completed (aka the Young farm explosion, and Klaus' hybrid slaughter). He concludes that Silas is in Mystic Falls to complete the third massacre. Stefan, Klaus, and Caroline begin their search for Silas at Professor Shane's office. Stefan believes that there will be something in his office that will reveal Silas's next move. Caroline jokes about the existence of an evil villain to do list that casually lists stealing blood and performing three massacres alongside more human activities like picking up dry cleaning. Klaus corrects Caroline and tells her that villains usually hire minions to pick up their dry cleaning. Caroline responds by sarcastically asking why Klaus is necessary to helping her and Stefan find Silas. Stefan reminds her that they don't know what Silas is capable of, and therefore having an immortal hybrid like Klaus on their side could be beneficial. Klaus adds that he and Stefan work well together, referring to their time in the twenties. Stefan reasons that they did at that time because his emotions were off and Klaus explains that it's why Stefan was more fun. He also notes that Damon is probably relishing in Elena's emotionless state in New York. Stefan argues that Damon knows what he's doing. Klaus questions this and warns Stefan not to underestimate the allure of darkness; that even the purest of hearts are drawn to it. Apparently impacted by his words, Caroline interrupts the conversation by introducing a book she found that might be of use. She opens the book to a section on expression triangles for Stefan and Klaus to examine. Stefan reads from the text, which states that in some types of magic, like expression, human sacrifice can be used as a focus for power. Two additional supernatural sacrifices can compound the mystical energy that creates an expression triangle. Caroline outlines the two massacres that have already taken place, emphasizing Klaus' hybrid failure in particular. Klaus points out that it wasn't exactly a failure before urging her to reveal what the third massacre  Klaus and Caroline examine the map without Stefan. Caroline notes the locations of the two massacres that have already taken place with a marker, reminding Klaus once again of how he slaughtered twelve of his hybrids. She connects both locations with a line as Klaus smirks at her. Recalling that the book dictates that the expression triangle is equilateral, she predicts the location of the third sacrifice by completing the triangle on the map. Amused, Klaus concludes that Caroline has been skipping her geometry classes. He argues that there are two possible locations for the massacre, as he completes a second triangle on the other side of the first triangle's base. In her defense, Caroline points out that Klaus didn't give her a chance to finish. They exchange lasting looks before Stefan returns to the office and informs them that he talked to Bonnie's dad and believes he's found Silas. Later, Caroline is follows Klaus in the woods as they use a map on Klaus' phone to track one of the possible sacrifice locations. Caroline demands to see Klaus' phone so that she can see where they are. Irritated, Klaus reminds her that she did have the option of accompanying Stefan to the other potential massacre location. Caroline explains that she wouldn't leave Bonnie's life in his hands. Still frustrated, she asks Klaus if he even knows how to read a map. Klaus informs her that he learned how to read a map from his friend, Magellan. She makes a sarcastic remark about him actually having a friend before wondering if he was drawn to his darkness too. Klaus states that he was referring to Damon and Elena when he made his earlier comment about the allure of darkness, but concludes that it struck a chord with Caroline. She denies that there is any allure to darkness. Klaus stops and turns to confront her. He asks her if she's “never felt the attraction that comes when someone who is capable of doing terrible things for some reason cares only about her”. Caroline acknowledges that she did once when she thought he was worth it, in obvious reference to Klaus. She continues by saying that some people can't be fixed; that people who do terrible things are terrible people. Visibly impacted by Caroline's harsh words, Klaus changes the subject back to the location of the sacrifice. Since there are no witches present, he concludes that they went to the wrong point. They meet Stefan at the correct point where the twelve witches are attempting to cleanse Bonnie. Stefan informs them that the witches are linked and that Bonnie is going to kill them. This won't happen if the witches kill her first, Klaus points out. Caroline urges Klaus that they need to save Bonnie. He reminds her that the only way to stop the witches is to kill them, which would give Silas what he wants. With the witch ready to kill Bonnie, Caroline intercedes and drives the dagger into the witch's chest. This kills the witch along with the eleven other witches present. This puts the massacre location into darkness as Caroline ensures Bonnie is okay. Klaus and Stefan look on with shocked and defeated expressions. Early the next morning, Caroline sits in shock as Klaus finishes burying the twelve witches who were sacrificed. Now that they are buried, Klaus concedes that it's almost like the sacrifice didn't happen, before he reminds Caroline that it did happen and now Silas has what he needs to destroy the other side. Caroline scoffs at his willingness to let Bonnie die. Klaus argues that one sacrifice (i.e. Bonnie) is less than the twelve witches Caroline sacrificed, to which Caroline responds by emphasizing that the one witch she saved was her best friend.

Klaus replies by telling Caroline to say whatever she needs to in order to sleep better at night. The significance of what she has done begins to dawn on her in that moment and she becomes emotional. Klaus touches her shoulder reassuringly and notes that she looks like she is in need of comfort. She nods slightly and Klaus responds by telling her to find someone less terrible that she can relate to - referring to Caroline's earlier disparaging comments directed at him. Disappointed and hurt by his words, Caroline pulls away and leaves him with a regrettable look on his face. In American Gothic, Klaus, who is shirtless and in pain because a piece of the white oak stake is still inside his back in a spot he could not reach. Caroline arrives. She touched his face, and she said, “As much as I’d love to watch you die, you still haven’t found me that cure.” It was Silas. He can take the shape of whomever he wants you to see. Then he left. Later Klaus was sweaty and cowering on the floor when Caroline came in again. He thought it was still Silas at first but then when Caroline remarked about how she should be running three prom committees at that moment. He told her about the white oak stake, and since he was hurt, she was the person to call. She found that hard to follow: He ran Tyler out-of-town and killed his mother. But, Klaus reminded her/us, if he dies, Caroline and everyone she knows dies. She had to help. He told her she’d need to cut the stake out of him. Caroline was having a difficult time getting the stake out of Klaus. Caroline finally smartened up: If Klaus wants her help; he has to let Tyler come back and promise not to kill him. Klaus could feel the splinters moving toward his heart and begged Caroline to help him, but she wouldn’t until he promised not to hurt Tyler. He wouldn’t do that because Tyler tried to kill him. This turned into a conversation about trust being the foundation of friendship, and Caroline angrily yelling that she should’ve turned her back on Klaus ages ago. That was a punch to the gut, but silver lining, Klaus’ pain was gone. Silas had gotten into his head and made him think he was dying. Caroline had taken Klaus’ mind off of it enough to break the spell, apparently. Caroline was ready to call it a night after using all of Klaus’ bleach to clean up. He thanked her for her help. She poked his chest when she told him if he needs anything else not to call her because she has a prom to plan. "Friends?" he asked, all smiley and adorable. She asked if he was letting Tyler come back to town. He didn’t answer, at first. But he did then say she might have noticed that he’s not exactly scouring the earth for Tyler. Then they shared a smile. In Pictures of You, Caroline interrupted Klaus' fireside brooding to inform him of the "real crisis" that was Elena's prom dress theft. The tailor couldn't remember who'd picked up the gown, which meant she'd been compelled. So the vervain is out of the town's water supply. Klaus laughed at Caroline, obviously, but she smiled and begged him to go into his "creepy trophy chest of family collectibles" and find her a gown that would make her look "Princess Grace of Monaco" hot. He couldn't refuse her so he helped. He was also out of the Lockwood mansion after Tyler showed up, he asked Tyler if it worth it, and then he gave five seconds to Tyler for leaving, after Tyler goes, Klaus look at the mansion with a regrettable look, knowing that Caroline is inside.

In The Originals (Episode), Klaus os standing in New Orleans. He calls Caroline and says, "Caroline, I’m standing in one of my favorite places in the world surrounded by food, music, art, culture, and all I could think about is how much I want to show it to you. Maybe one day you’ll let me."

Then he smiles. In She's Come Undone Silas takes the form of Klaus and shows up to Caroline in front of the Salvatore's house. Caroline is surprised to see him, and she seems glad. After that, they walk through the forest and they start talking. Caroline says that everyone said the he was gone for good, and Klaus/Silas admits that he couldn't leave before he said goodbye to her. Then Caroline tells him that he doesn't owe her anything, that he moved on and that he should just go, but she showed some sadness during that. "Klaus" declares that he didn’t  have any intended to move on and that the truth is he couldn't stop thinking about her. Caroline walks away and Klaus tries to stop her and tells her to come to New Orleans, then asks her what  she’s so afraid of. Caroline answers:

"You. I am afraid of you."

Later, Caroline figures out its Silus, and then he stakes Caroline with a branch, making her pass out. In Graduation (Episode), Caroline repeatedly calls Klaus for help but she still gets no reply. The witches that Caroline killed showed up to get revenge until Aja gets decapitated by a graduation cap thrown at her by Klaus. Klaus saved Caroline and the others. He threatened to speed-toss more caps, and the ghosts retreated. Caroline smiled at him, happy to see him.

Caroline, we learned, had sent Klaus a graduation announcement  “hoping for cash,” he joked. “Or a mini fridge”, she joked back. He'd thought about offering her a first-class ticket to New Orleans, but then he chose for something she'd use: He was letting Tyler come back to town.

"He's your first love. I entend to be your last. However long it takes,"

he said. He kissed her on the cheek and escorted her back home. Leaving Klaus to head off into the The Originals (TV Series) and maybe one day Caroline will join him.

Season 5
Caroline Mentions Klaus in Monster's Ball In 500 Years of Solitude. Caroline is searching in the woods for Matt who has been kidnapped and locked in the safe and then Klaus appears, she is shocked but she behaves in a way unfriendly towards him. But Klaus keeps following her, he tells her that he has returned about the news about Katherine but Caroline isn't interested in the conversation because she has to keep looking for Matt and moves away with her vampire speed but Klaus returns to follow her. Klaus stops her and talks about Tyler, Caroline asks if he’s killed Tyler, and Klaus assures her that he "let him go with little bruises". They talk, and Klaus claims the reason he returned to Mystic Falls was to "gloat over Katherine's corpse-to-be" now that the one person he'd hated and pursued almost relentlessly for more than half of his time was finally dying. Caroline tells him off and speeds away. Klaus catches up to her, again, and reveals that Rebekah has already rescued Matt from the safe. Klaus comes clean and informs Caroline of the real reason for his return to Mystic Falls; he wants genuine answers about her feelings towards him, and that not only is he willing to give up his feuds against both Katherine and Tyler for her if she will be honest with him, but if she tells him the truth he will leave and never return to Mystic Falls. Caroline goes on the defensive, saying that she's at college and planning a life for herself, and none of her dreams involve Klaus in the least. Klaus understands, but counters that she is still afraid of him. Caroline elaborates that she is more afraid of how she feels about him than he himself, that she thinks it is wrong to feel this way about him, but finally gives into her desires and kisses. Klaus smiles. Caroline herself is positively glowing, and kisses him again, this time with Klaus responding. Klaus pushes her against a tree, and they begin to strip each other’s' clothes off. What can only be described as "hot vampire-hybrid sex”. Caroline herself does not return to the Salvatore boarding house until nightfall, with a leaf in her hair and messy clothing.

In The Devil Inside, Caroline tells Katherine (who is impersonating Elena) that she kissed Klaus and that she felt so good doing it that she ended up having sex with him. Katherine purposely makes that Tyler listen the conversation, he gets furious and Caroline follows him to talk to him, Tyler reminds her of everything bad that Klaus did, Caroline tries to explain but he was even more furious until Stefan stops him.

In Total Eclipse of the Heart, Caroline states that she has been on edge because of the Klaus and Tyler situation. Whilst attending the "Bitter Ball" at Whitmore College with "Elena", Caroline is seen shredding the pony drawing Klaus gave to her in Dangerous Liaisons, she says that she is making a decision and that these relationships are over because she wants a a fresh start.

In No Exit, at the Salvatore's house, Caroline is standing in front of the fireplace, and Stefan arrives, Caroline tells him, that she knew that the Klaus thing was gonna come with consequences and that now she just have to deal with it and learn from her mistakes.

In Gone Girl, Caroline is talking with Tyler and he says that she always sees the good in people, referring to Klaus, Caroline tells him she saw the good in Klaus and that she is a vampire with the same impulses as him, so she is allowed to make some mistakes along the way. That she slept with Klaus after Tyler left her, that she don’t need to be hearing about it every five seconds and that she is done feeling guilty about that.

In While You Were Sleeping, Enzo said to Caroline that Damon said that she had a "thing for accents." This may refer to Klaus by the fact that he has British accent.

The Originals
In Bloodletting, when Klaus and Tyler are about to face off in a fight, Klaus tells Tyler that he is very surprised because he is able to hurt a pregnant woman referring to Hayley only for revenge, and he asks him what Caroline think about that, Klaus says that perhaps he will call her to tell her what Tyler has done but after killing him, Tyler says that whatever he does to him Caroline will never stop hating to him, which bothers Klaus and he reacts, pushing Tyler against a tree.

Caroline was referenced in Dance Back from the Grave as Marcel mentioned that Klaus is in a good mood and should go back to Mystic Falls more often.(Right after TVD 500 Years of Solitude
