Elena, Stefan, Damon, and Clara are in a classroom talking about Caroline.
"How did this happen?" Clara asks trying to figure out how Caroline went from nearly dying in the hospital to walking around a vampire.
"Bonnie asked me to fed her my blood, we thought she'd be safe at the hospital but obviously Katherine got to her," Stefan explains.
"But why?" Elena asks,
Claire clenches her fists and pushes off the wall, "because Katherine is a manipulative, nasty, little slut."
Damon smirks, "look at you using your 21st-century vocab words I gave you." Clara smiled, flattered at the praise but Elena just rolls her eyes.
Stefan is pensive, "she said game on? What does that even mean?"
"It means she's playing dirty. She wants us to know," Damon tells him.
"But why Caroline?" Elena complained, trying to get the focus back on her friend.
"I don't know," Damon shrugged not really caring.
"Poor Caroline," Clara muttered making Damon scoff, "Oh please,"
Stefan shakes his head, "no, she's right, Caroline must be completely out of her mind, she doesn't even know what's happening to her... We have to find her."
"Yep, and kill her," Damon finishes,
Clara is shocked, "what? WHY?" She had seen Damon kill but hearing him talk so casually about a young girl's life was somehow more troubling to Clara, it was callous.... she didn't like it.
"You're not gonna kill Caroline!" Elena threatens.
Damon rolls his eyes, "she knows who we are. She's officially a liability, and we've got to get rid of her."
Stefan shakes his head, "Damon, absolutely not."
"Need I remind you of a tragic little story of a girl named Vicki Donovan? Caroline, of all people, will not make it as a vampire. Her mother is a vampire hunter. Guys come on, we all know how this story's gonna end, just flip to the last chapter and..."
"It's not an option Damon," Elena tells him.
"No? Your silence is deafening, Stefan. Wait, wasn't there a school carnival the night you staked Vicki? I never had a town where history doesn't repeat itself. You know I'm right."
"We're not gonna kill her," Stefan says leaving the classroom with Elena following behind him.
"She's Liz's daughter, Damon." Clara tries to appeal to any part of the Damon she knew that might still be in there.
Clara catches up to Stefan and Elena to look for Caroline and leaves Damon to do some thinking hopefully.
Elsewhere, Matt is talking with Bonnie.
"She's obviously pissed at me for something but for what, no clue."
"What happened?" Bonnie asks,
"She freaked out and she's been like that all day. Cool one minute and crazy and neurotic the next."
"She almost died, it's bound to mess with her head. Plus, she's Caroline."
"Yeah, I'm used to the insecurities and all that. It's who she is, love it or hate it, but this seemed...I don't know...different...more. I can't explain it."
Elsewhere:
Damon is looking for Caroline. He notices a wooden tent peg in the ground. He walks over and takes it.
Meanwhile:
Elena, Stefan, and Clara are continuing their search.
"You agree with Damon, don't you?" Elena asks, "Stefan!"
Stefan punches the side of a trailer, "Damon's right, not about what we should do but about what's gonna happen. Katherine already signed Caroline's death sentence."
"Well we can't let it end that way," Elena complains shaking her head, "she's doing this to get to me, isn't she?"
Stefan disagrees, "actually, she's doing it to get to me."
Clara having all she can take of these two pipes up, "could either of you be any more self-involved? She's done this to Caroline, end of story, now lets just focus on finding her before Damon does, he might not realize it now but he'll regret it if he kills her."
Stefan rolls his eyes, "trust me Damon's never regretted a kill."
Clara clenching her jaw tired of Stefan's attitude, "trust me, my husband will regret causing Sheriff Forbes pain... whether or not he's willing to admit it, she's his friend and friendship means something to him."
"Wait, stop... do you smell that?" Stefan says halting them.
"No... smell what?" Elena asks,
Clara looks to Stefan, "blood..."
"Blood, as in Caroline's? Where could she be?" Elena says starting to panic
Stefan moves his head in another direction, "What is it? Do you hear her? What's going on Stefan, what is it?"
"It's not Caroline's blood... it's human," he says filling Elena in.
"What does that mean?"
Elsewhere:
Damon finds Caroline, she is crying next to Carter's body with blood all over her face.
"He's dead. I killed him. What's wrong with me?" She asks starting to break down.
"Hey, hey it's okay. I can help you," Damon says trying to be comforting,
"You can?" Caroline looks up at him hopeful,
"Yeah, I have to."
"What are you gonna do?" She asks,
"The only thing I can do." Damon speeds and snaps Caroline's neck temporarily killing her.
He looks down at the stake and regretfully tosses it still not confident this is the smartest thing to do.
Clara Stefan and Elena catch up to him and see him carrying Caroline,
"Oh my god, we're too late!" Elena says bringing her hands to her mouth in horror.
"Relax, I just snapped her neck, clean up whoever this kid is (he gestures to the boy Caroline just killed) I'll put her in the cellar until we figure out what to do."
Elena follows Damon to the boarding house to try and help with Caroline and Stefan and Clara are left to clean up.
A little while later Bonnie arrives
She sees Clara and Stefan over the teen's dead bloodied body,
"Carter?"
Stefan sighs, "It's okay, come on."
Bonnie sees his blood on Clara and mistakenly thinks she's responsible,
"I knew you'd slip up, that you'd bring death and destruction to this town!"
"Bonnie?" Stefan looks between Clara and Bonnie and realizes what Bonnie has assumed happened,
"No, Bonnie, that's not what happened."
"Don't defend her Stefan! I warned you, and your brother!"
"Bonnie I swear she had nothing to do with this!"
"I don't believe you!"
Bonnie looks at Clara and gives her the most painful aneurisms she can manage. Clara falls to the ground clutching her head and curls up.
Not letting up Bonnie opens a faucet with her powers and water starts coming out a hose.
"I told you what would happen if you hurt anyone."
"I didn't do this." Clara manages to squeak out,
"Bonnie, it's the truth, this wasn't down to her," Stefan says trying to convince her.
"Ever since she got here things have just gotten worse, grams died, the tomb vampires were set free, it's all her and Damon's fault!"
She creates a fire and it quickly spreads towards Clara,
"Bonnie, what are you doing? Bonnie stop it!" Stefan can't get through to Bonnie and he now sees Clara is starting to burn, he can't let this happen! He runs up to Bonnie and tries shaking her,
"Bonnie, Bonnie, stop it! You're going to kill her!"
Clara is still burning, finally, Stefan not knowing what else to do grabs Bonnies head and screams in her face, "IT WAS CAROLINE!!!!!!!!"
The fire goes out as Bonnie's concentration is broken.
"What did you just say?"
Stefan sighs, "Katherine turned her, she didn't know what she was doing... it was Caroline, Bonnie.... Caroline's a vampire."
Bonnie shakes her head not wanting to accept the truth, "No... No, you wrong,"
"I'm not, I'm sorry Bonnie, Damon and Elena just took her to the boarding house to explain things and get her under control."
Bonnie looks down at Clara, who's body has started to heal its self and then over to Carter, she's in shock and slowly leaves to see for herself if Caroline really is a vampire now.
Stefan runs over the Clara and drags over Carter help, he lifts her head up and helps her to bite into his wrist.
"I'm so sorry I didn't stop her sooner, let's get you home."
"We can't... Carter" Stefan sighs, she's right,
"Wait here, I'll be right back."
At the Boarding house, Caroline is locked up in one of the cells,
"When will she come to?" Elena asks,
"Soon." Damon tells her.
"Thank you for not... you know."
"I didn't do it for you, and I still say its gonna bite us on our ass."
"I just can't believe what this day has turned into."
"You and me both,"
Damon hears the door bang open and soon Bonnie races down the stairs,
Elena looks over at her friend, "Bonnie? What are you doing here?"
"Is it true? Is Caroline..."
Elena sighs sadly, "yes, its true."
"I'm sorry."
"What are you sorry for this isn't your fault Bon."
"Not about Caroline...about Clara."
That gets Damon's attention, "What about Clara?"
Bonnie turns to Damon, "I saw Cater, and then Clara had blood on her... I thought."
Damon very menacingly gets right in front of Bonnie, "What did you do?"
Bonnie gulps but answers him, "I set her on fire."
In a flash Damon has Bonnie against the far wall choking the life out of her,
"NO! Damon stop please!" Elena begs,
"Why should I?"
"This can't be us okay? Always attacking each other, and Stefan! Stefan was with her, he wouldn't let anything happen to her!"
"You better pray that's right because if it's not, I won't only come and finish of Bon Bon here, I'll come for you too!"
With that Damon zooms out of the house to find his wife.
