Amity walks into Alaric's apartment after running a couple errands for her brother "Nik?" she calls out. "In here Am." Klaus calls back. Walking through slightly more Amity finds Klaus in Alaric's body and Katherine tied to a chair. "Hello Katerina. I got the stuff so I can spell myself, so I can get in the Boarding a house." she explains looking at her brother. Klaus nods and opens the closet taking 2 shirts out "Oh! Who is this guy, Safari Sam? Ok, bad, or badder?" he asks showing them to Katherine and Amity. "Dark colors suit you better." Amity tells him. "Oh, thank you, honey. Ok, pop quiz. The dagger and white ash are in the Salvatore's possession, correct?" Klaus asks turning to Katherine. "The dagger was used to kill Elijah. You'll find him in the basement of the Salvatore house." she responds. "Ok, that dagger needs to stay exactly where it is. The last thing I need to do is resurrect Elijah. Ohh, that guy is a buzzkill." Klaus says making Amity roll her eyes at him before leaning against the wall. "Don't forget you're on the outs with your girlfriend Jenna." Katherine reminds Klaus. "Right. Elena's aunt. For all the lies about Isobel. What else?" Klaus asks her. "That's it." she responds. Looking at Amity Klaus gets closer to Katherine and touches her face. "Oh, so jumpy." Amity smirks. "Please, just... kill me. I've told you everything that I know." Katherine begs. "You see, I believe that you believe that but what would you not know? What could they be keeping from you? Hmm? Anything? Tell me." Klaus compels. "They were trying to see if Bonnie could find a way to kill an Original without a dagger." she says. "Bonnie the best friend? And then you said she didn't have her powers anymore." Klaus glares. "She doesn't or didn't. I don't know. You kidnapped me, remember? I'm kinda out of the loop." Katherine defends. "Well, we'll have to get to the bottom of that." Amity comments.
"Please, just kill me, Klaus, and be done with it." Katherine begs again. "And show you kindness? I've searched for you for over 500 years. Your death is going to last at least half that long. I want you to take this knife... And stab yourself." Klaus tells her handing her a knife from his pocket. Taking it Katherine stabs herself in the thigh. "Now take it out." Klaus tells her. "Now while we're gone, I want you to do that over and over and over again and if you get bored, switch legs." Amity compels her. "Where are you going?" she asks the siblings. "I'm gonna go lay eyes on my precious doppelganger Oh, don't look so glum, Katerina. The fun is just beginning." Klaus responds kissing her forehead. "Again, please." Amity says smirking as she leaves. "So what's the story?" she asks looking at Klaus. "You're Alaric's Goddaughter who is travelling and decided to pop in to say hello." he tells her. Amity nods in response "Okay, can I keep my accent though? You know I hate doing an American accent." she asks. Klaus chuckles but nods "Anything for you little sister." he tells her. Klaus stops the car "You go feed, just keep a low profile we don't want them catching on yet." he says. "Okay, call me when school finishes." Amity says kissing his cheek and jumping out the car.
Later Amity sits in the car as Klaus drives to the Boarding House "Anything interesting happen at the school?" she asks him. "Not really, just saw the Doppelgänger and her friends. Taught them about the sixties ready for their decade dance. What about you?" Klaus responds. "I found a beautiful brunette to feed from. Honestly she was like a 9 out of 10." Amity smiles making Klaus chuckle at her. "You could have just compelled her to be with you." he says. "Nah, she was a bit too... Rebekah-ish." Amity responds as they pull up to the house. Together they get out the car and knock on the front door before walking in. "There you are." Damon says. "Sorry I'm late." Klaus says. "Hey, I need you to put me down as a chaperone at the dance tonight. Klaus made his first move. Who's this?" Damon asks looking at Amity. "Amity Carson, Alaric is my Godfather." Amity smiles crossing arms. "Goddaughter?" Damon asks looking at Klaus. "Yes, she knows about the supernatural and she wants to help." Klaus responds putting an arm round Amity's shoulder. Damon frowns slightly "What can she do?" he asks. "Damon enough, we need all the help we can get." Stefan cuts in. "Ok, so we find him and then what, hmm? What's our plan of attack?" Elena asks. "Me. I'm the plan. He has no idea how much power I can channel. If you can find him, I can kill him." Bonnie tells her. "That's not going to be that easy. I mean, he is the biggest, baddest vampire around." Klaus comments. "Alaric has a point. I mean, what if he..."Damon says cutting off as he rushes over to Bonnie who throws him to the other side of the room with her powers. "Well, I was impressed. Stefan comments making Amity shrug. "It doesn't matter if he's an Original. I can take down anyone who comes at me. I can kill him, Elena. I know I can." Bonnie says.
Klaus and Amity walk back into Alaric's apartment to finding Katherine sat with her legs bleeding. "Ah, you're right. This witch is all juiced up and aiming to kill." Klaus tells Katherine. "That's terrible." she respond. "We're gonna have to kill her, Maddox." Klaus says making their Warlock walk over. Amity looks through Alaric's closet "Do you think this Alaric guy has anything vintage?" she asks. Looking under the shirts she finds a load of weapons "Crossbows, wooden bullets and automatics? Who is this guy, again?" she asks. "He's the local vampire hunter." Katherine responds. "Ahh. Well, that explains the clothes." Klaus remarks. Maddox walks over and hands Klaus a glass of bourbon "All I could find. Guy likes his bourbon." he tells them. "I knew there was something about him I liked. There's a high school dance and I'm gonna need you to take out witch bitch." Klaus explains. "If she has that much power, she can sense me coming from a mile away. I won't be able to get near her. You have to do it." Maddox explains. "In this body? I'm a Haggard history teacher. She can easily hurt me. I mean, not me, Klaus me, but you know what I mean." Klaus responds. Amity shakes her head "what he means is that no witch could handle channeling that much power. It'll kill her. It would kill him. You just have to make her use it." she tells her brother. "You mean like provoking her to death?" he asks making Amity nod. "Won't take long. Just keep attacking her until it kills her. His body, Alaric's, will last longer than hers will." Maddox says. "How? He's human." Klaus asks. "I can help in that department. I can do a spell to protect you." Amity assures her brother. Smiling Klaus kisses her forehead before going to find something to change into.
Amity walks out of the bathroom and does a little twirl as Klaus looks at her "What you think?" she asks. "Beautiful as always Little Sister." he responds kissing her head. Amity smiles and links arms with him "Shall we?" she asks. "We shall." Klaus smiles leading her out the apartment and to the car.
At the school Amity stands next to Klaus as two students walk over to them "Nice outfit, Mr. Saltzman. Totally far out." the girl says. "Thank you, Dana. Thank you. Now who is your date?" Klaus asks. "It's Chad, Mr. Saltzman, from third period." Chad says. "Chad, of course. How would you and your friends like to earn a little extra credit?" he asks before compelling them both. Amity smirks as the students walk off, Dana to the stage and Chad to the hallway "Having fun brother?" she asks quietly. Klaus smirks and gives her a subtle nod in response. Dana walks on stage and takes the microphone "Thanks for being here, everybody. We have a special shout-out tonight. This is for Elena from Klaus." she says. A song starts playing as Amity giggles "When can I have my fun?" she pouts. "Soon, promise." Klaus assures her as Damon walks over. "Special dedication, huh? This guy's a little twisted." Klaus tells the eldest Salvatore brother. "I'm not impressed." Damon responds. "No?" Amity asks. "Let me know if you see anything out of whack." Damon says before walking off.
A little while later klaus and Amity rush over to Elena and Bonnie "Elena!" Klaus says gaining the girl's attention. "What is it?" Elena asks him. "He has Jeremy." Klaus tells them. "What?!" both of them asks. "Yeah, Klaus has Jeremy. Come on." Amity tells them before turning and leading them out of the hall and down a corridor. "Ok, so where are you two taking us?" Elena asks. "Just a little further." Amity tells them, seeing Klaus smirk out of the corner of her eye. "What... Something's not right." Elena tells Bonnie. "Where's Jeremy?" Bonnie asks the siblings. They stop and Klaus and Amity start laughing "I just had to get away from that dance. The sixties, uchh. Not my decade." Klaus says making Amity giggle. "I mean, whose call was that, anyway? I much prefer the twenties. The style, the parties, the jazz." Klaus continues Amity nodding in agreement. "Alaric, Amity. Are you on vervain?" Elena asks. "Now why would you ask us that question, Elena?" Amity asks sweetly. "They're being compelled." Elena tells Bonnie. "Nope. Try again." Amity smirks. "What's going on?" Elena asks. "Ok, I'll give you a hint. I am not Alaric and Amity here isn't his Goddaughter." Klaus tells her. "Klaus." Elena realises. "Surprise!" Klaus smiles. "Nik, she doesn't know who I am though!" Amity pouts. Klaus smiles "I'm sure she'll work it out love." he assures her. "Oh, no. No, it's not possible." Elena denies. "Just relax, Elena. I'm not here to hurt you. You're not on my hit list tonight. But you are." he says looking at Bonnie. Bonnie throws him against the wall with her powers but he just gets up again. "Now, did I mention that I have a witch? You're gonna have to hit me a lot harder than that." Klaus smirks before rushing over to her. Bonnie throws him against a display case making him laugh "By all means... Fire away! If you kill this body, I'll just get a new one. Maybe Jeremy." Klaus smiles standing up again as Amity leans against the wall smiling. "Go. Run. Run!" Bonnie exclaims before she and Elena run off. Amity goes over to Klaus "Where to?" she asks. "How about the cafeteria?" Klaus asks putting out his arm. Giggling Amity nods and takes his arm letting him lead her into the cafeteria.
As Amity sits next to Klaus Bonnie enters the cafeteria "What took you so long? Now, do you want to do this the easy way or the hard way?" Klaus asks her. Bonnie breaks his wrist with her powers but Klaus just pushes it back into place. "The hard way. Got it." Klaus comments standing up. Amity goes to get up but Klaus puts his hand out to her making her stop. Bonnie breaks Klaus' shoulder with her powers making him groan "What? You'd kill your favorite history teacher?" he asks. "It's what Alaric would want. And he'd want you to suffer first." Bonnie responds as her nose starts bleeding. "Look at you. Is that all you got?" Klaus asks as Bonnie wipes her nose. "Let's find out." she tells him. As they carry on fighting Amity smiles when she sees that Bonnie's nose is bleeding even more. "Bonnie, no!" Elena shouts trying to get into the cafeteria with Stefan. Bonnie looks at Elena with a smile before falling to the floor. Amity grabs her brother and speeds the out the building and back to the apartment.
