Gilbert Residence.

Elena hands her sister the ice pack.

"Thanks. (Margaret puts the ice pack on her head.) Ow!" Margaret said

"What happened?" Stefan asked Margaret

"I don't know. One minute I was sensing a vampire...then the next...everything went black." Margaret explain

"How can a vampire be invited in if the tomb vampires are dead?" Elena asked Stefan

"I don't know." Stefan said

"Have to see if Caroline is ok and John is going to the hospital too. With Jeremy's little stunt." Elena said

"What?!" Margaret asked in confusion

"I'll explain it in the car. Come on!" Elena said


Hospital.

Both Margaret and her sister approaches to Bonnie.

"How's Caroline?" Elena asked Bonnie

"She's weak. They don't know if she's going to make it." Bonnie said

"No. No." Margaret said

Bonnie hugged both Margaret and Elena. Margaret senses a vampire nearby and it was Damon. He approaches to them.

"Is there something that you can do? Like a spell or something?" Elena asked again

"She doesn't know how, do you?" Damon asked Bonnie

"No, I don't." Bonnie said

"No, you don't because it took Emily years to learn a spell like that." Damon said

"Well, I can take down a vampire, that spell was easy to learn." Bonnie said

"I can give Caroline some blood." Damon said

"No, no way." Elena said

"No, just enough to heal her. She will be safe in the hospital and it will be out of her system in a day, she will be better." Damon said

"It's too risky." Margaret said

"Do it. (Bonnie sees both Margaret and Elena's expression) This is Caroline. We can't let her die. Do it." Bonnie said

"If I do this, you and me, call a truce?" Damon asked again

"No. But you'll do it anyway. For Margaret." Bonnie said

Bonnie leaves. Elena, Margaret, and Damon are alone.

"I know this is probably the last thing you want to do right now but we should talk about what happened tonight." Damon said

"One of the tomb vampires came in the house and knocked me out cold." Margaret said

"And almost killed John." Elena said

"What? When? What are you two talking about? After I left?" Damon asked in confusion

"You were there?" Elena asked in confusion

"We were arguing about Margaret and..." Damon said as he was cut off by Jenna

Jenna arrives. Damon moves away as he listens in.

"Elena, I came as soon as I got your message. How is John?" Jenna asked her niece

"Where have you been?" Elena asked her aunt

"At the fire department, I had to fill out a report. I told you earlier." Jenna said

"No, you didn't." Elena said

Yes, I did." Jenna said

"No, Jenna, you didn't." Elena said

"Yes, I did." Jenna said

Damon suddenly realizes that Katherine was the one he argued with and not Elena.

"Oh! (Jenna and both of her nieces look at Damon in confusion.) Mmm, yougotto be kidding me." Damon said as he walks away


Gilbert Residence

Margaret, Elena and Damon enter the house. Stefan is on the floor but stands up immediately.

"Stefan?" Elena said

"Elena." Stefan said

"What happened?" Elena asked Stefan

"Katherine happened." Damon said

Both Margaret and Elena go upstairs and enter Jeremy's room.

"What's going on?" Jeremy asked both of his sister's

"We have to tell you the whole truth." Margaret said

Jeremy realizing more to the story.

"What happened downstairs. My ancestor Katherine Pierce posing as me." Elena said

"Are you saying that she looks like you?" Jeremy asked his sister

"Yes. Doppelganger." Elena said

"What's worst is that John is a horrible parent." Margaret said

"What?" Jeremy asked in confusion

"Elena and I are...half sisters. We just found out today that John is our father." Margaret explain

"That's..." Jeremy said as his sister interrupted his sentence

"We know." Elena said

Both Elena and Margaret enters the room. Stefan walks towards her.

"We told Jeremy." Margaret said

"We can't lie to him anymore." Elena said

"Are you alright?" Stefan asked Elena

"No, I'm not alright. I thought that with all the tomb vampires gone things would get better." Elena said

"I know. We all did." Stefan said

"Katherine was in this house, that means she's been invited in, what are we gonna do?" Elena asked in confusion

"Move." Damon said

"Well that was helpful." Margaret said as sits down

Damon looked at Elena.

"Katherine wants you dead; there's zero you can do about it; you would be dead but you're not. So clearly she has other plans." Damon said

"Right and we need to find out what those other plans are and not provoke her in the process. What happened tonight when you thought she was Elena?" Stefan asked his brother

Damon looked at his brother.

"To risk another frown line encroaching on a very crowded forehead. I was arguing with her." Damon said

"About what?" Stefan asked again

"Me and Margaret. Of how I should stay away from her. Exact same thing that Stefan said." Damon explain

"And you thought it was me?" Elena asked Damon

"I didn't stay away from Margaret When she got here. We...kissed." Damon said

Both Elena and Stefan were shocked when they looked at Margaret.

"I can explain." Margaret said

Stefan looked back at his brother.

"What do you mean you kissed?" Stefan asked again

"Well, you know, when two lips pucker and they go. (Damon puckers his lips and makes kissing noises. Stefan rushes at him with his super speed but Damon uses his super speed as well and stands next to Margaret.) Don't be obvious, Stefan." Damon said

Stefan starts towards Damon again but Elena puts her hand in front of Stefan.

"Stefan wait. Maybe there's a mistake. (Both Elena and Stefan looked at her sister.) Did you?" Elena asked her sister

Margaret looked guilty.

"Yes. I kissed him. It was a one time thing. But right now is not the time to play alpha male." Margaret said

"John must know something. There has to be a reason why Katherine tried to kill him." Elena said

"She's Katherine. She loves to play games and you're fooling yourself if you think you're going to find out what she's been up to before she wants you to know." Damon said

"No, actually Elena's right, John could know something through Isobel. Your mother, she was in touch with Katherine so maybe we can go to the hospital and get him to talk." Stefan said

"I've got a better idea." Damon said

"What's that?" Margaret asked Damon

"I'm just gonna ignore the bitch. See you." Damon said

"Seriously?" Margaret asked Damon

"If Katherine thinks she's been ignored it will lure her out, she'll make a move." Damon said

"Yeah? And then what?" Stefan said

"Stake her, rip her head off, something poetic. We'll see." Damon said as he leaves

"You got some explaining to do." Elena said

"It was just an accidental kiss." Margaret said

"Why did you do it?" Stefan asked Margaret

"I don't know. Ok. I just feel confused." Margaret said


Next day.

Hospital.

Stefan, Margaret, and Elena are walking down the hallway to John's room. They enter the room together.

"John? (John opens his eyes and panics when he sees Elena. He tries to press the button to call the nurse, but Stefan grabs his hand and takes it away from him.) I'm Elena. I'm not - I'm not Katherine." Elena said

"We know she did this to you." Stefan said

"We need to know why." Margaret said

"Where is she?" John asked them

"You tell us. (John tries to sit up but Stefan pushes him back down.) You're a little too weak to play tough guy. Why don't you just sit back and answer a few questions?" Stefan asked John

Elena places the Gilbert ring into John's hand.

"Please, tell us why she's here. What does she want?" Elena asked her father

John doesn't respond.

"She'll try again; we can't help you if you don't confide in." Stefan said

"In you?" John asked Stefan

"Both of your daughters." Stefan said

"Both of my daughters should have driven a stake through your heart by now. (John looked at both Elena and Margaret.) I never spoke with Katherine directly, she never trusted me. (He looks at Stefan.) So either kill me or get out because I can't stand the sight of you with either of my daughters." John said

"That device almost killed me. I guess you would kill your other daughter as well." Margaret said as she leaves

"Margaret! MARGARET!" John yells


Outside.

They're walking away.

"We have to swing by home to pick up Jenna and Jeremy so we can go to the Lockwoods'. How did you leave him there, John?" Elena asked Stefan

"I...I asked him to leave town." Stefan said

They stop walking and look at each other.

"Asked? You threatened him." Elena said

"Yeah, I threatened him." Stefan said

"Thank...you. We would've done that sooner." Margaret said

"We don't want someone like that in our lives. Or Jeremy's life." Elena said

"Or my mother's." Margaret said

"I know." Stefan said

"So what now?" Elena asked again

"Now, I need to go find Damon." Stefan said

"He's not the problem, Katherine is. She's messing with his head." Margaret said

"The last thing we need is to make things worse." Elena said

"I'm not gonna let you hurt him." Margaret said

"So you do like him?" Stefan asked Margaret

"I...don't." Margaret lied


Lockwood Mansion.

Margaret, Elena, Jenna, Jeremy, and Elizabeth arrive.

"Looks like the whole town has turned out." Jenna said

"Yeah. Well he is...he was the mayor." Elena said

"Poor Tyler." Margaret said

"Why don't they save it for the funeral?" Jeremy asked them

"That's what people do." Elizabeth said

"The Lockwoods were here for us when we went through this. It'll be quick; we'll drop off the food and pay our respects and go." Jenna said

"In and out? It sounds like a plan." Jeremy said

Margaret sees Damon.

"You guys go ahead, I'll be right there, okay? (Margaret goes toward Damon.) Hey, how are you doing?" Margaret asked Damon

"Great Margaret. Walking on the sunshine, thanks for asking." Damon said

"Damon." Margaret said

"Margaret." Damon said

"We should be able to talk about this. Damon, we're close enough now. I really want to know how you are doing." Margaret said

"I kissed you. I thought you had feelings for me as well. How do you think I'm doing?" Damon asked Margaret

"I think that you're hurt." Margaret said

"No, I don't get hurt, Margaret." Damon said

"No, you don't admit that you get hurt. You get angry, always hiding it and then you do something stupid." Margaret said

"You're afraid that Katherine is gonna send me off the deep end. I don't need her for that. (Damon begins to leave but stops.) Let me ask you this. Why isn't such a surprise of telling people about last night? When we kissed?" Damon asked again

"I'm surprised of what people would think if I actually started a relationship with you. You and I could never work." Margaret said

"Now I'm hurt." Damon said

Damon turns to leave again. Both Elena and Bonnie runs up to them with worried looks on their faces.

"What happened?" Margaret asked both Margaret and Elena

Both Elena and Stefan are sitting on a bench on the Lockwood grounds. Elena is wiping Stefan's wound with a cloth. Margaret is standing up.

"You gonna be okay?" Elena asked Stefan

"Yeah, it will heal." Stefan said

"That's not what I meant." Elena said

"I was trying to figure her out. I was playing along and I let her get to me." Stefan said

"Looks like she's playing in your head too." Margaret said

Damon arrives.

"I tried to track her but she's gone. Oooh, cover up, Fabio. (Stefan pulls his shirt down.) We got a crazy ex on the loose. (Damon looks at Elena.) You better watch out, looks like Katherine is trying to steal your guy." Damon said

"That's not what's happening." Stefan said

"We're gonna go check on Jenna, Jeremy, and my mom." Margaret said

Both Margaret and Elena left.

"Katherine is gonna try to play us against each other, you do know that right?" Stefan asked his brother

"Brother, don't you worry, our bond is unbreakable." Damon said

"We need to stay united against her. So yes, as much as I would like to kill you, I'm not gonna fight you." Stefan said

"I kissed Margaret." Damon said

"She was there for you. I'll give you that. You feel something for her. You care about her. But I'm not gonna let Katherine come in here and destroy that part of you that is finally, after all of this time, willing to feel something. She will try to break you, she will try to break us and how we respond to that will define us. It's our choice.

Stefan looks at his brother and leaves.


Night.

Morrow Residence.

In the kitchen.

"What's going on with you and Damon?" Elizabeth asked her daughter

"Not you too. It was nothing." Margaret lied

"Margaret?" Elizabeth said

"Mom, I know you're trying to be that concern mother. But he's being Damon. There's nothing going on between me and him." Margaret kept lying


Salvatore Boarding house.

Damon walks into the living room and pours himself a drink. He starts to walk out but stops.

"Very brave of you to come here." Damon said

Damon turns his head. Katherine is sitting on the couch.

"I wanted to say goodbye." Katherine said

"Leaving so soon?" Damon asked Katherine

"I know where I'm not wanted." Katherine said

"Don't pout. It's not attractive on a woman your age." Damon said

"Ouch." Katherine said

Damon drinks his drink and starts to walk out of the room. Katherine superspeeds in front of him.

"What, no goodbye kiss?" Katherine asked Damon

"Why don't I kill you instead? What are you doing here?" Damon asked again

"Nostalgia, curiosity, et cetera." Katherine said

"I'm better at the enigmatic one-liners, Katherine. What are you up to?" Damon said

"Trust me Damon, when I'm up to something, you'll know it. Come on. Kiss me. Or kill me. Which will it be, Damon? We both know that you're only capable of one thing. (Katherine inches closer towards Damon's lips. He turns and walks away. She rushes in front of him again and grabs him by the throat. She pushes him down to the floor and lies on top of him.) My sweet, innocent Damon.

Damon turns himself on top of her and grabs her by the throat. After a few seconds of hesitation, he kisses her. She vamp speed him against the wall. She rips his shirt open. They continue kissing. He knocks books off a nearby table and pushes Katherine down onto the table. He continues kissing her neck, then pauses.

"Okay, wait, brief pause. (Katherine casually pushes Damon off of her and stands up.) I have a question. Answer it and it's back to fireworks and rockets red glare. Answer it right and I'll forget the last one hundred and forty five years that I've spent missing you. I'll forget how much I loved you, I'll forget everything and we can start over. This could be our defining moment because we have the time. That's the beauty of eternity. (Damon gently caresses Katherines face.) I just need the truth, just once." Damon said

"I already know your question and its answer. The truth is...I've never loved you. It was always Stefan." Katherine said

Katherine takes Damon's hands off her face and leaves.

"Margaret cared about me more then you. She was right about you." Damon said

Katherine stops and turns around.

"And that's what?" Katherine asked again

"You seduced me and treated me like dirt. And you're just a coward." Damon said

Katherine leaves.


Gilbert Residence.

Margaret senses Damon upstairs.

"You got to be kidding me. (Margaret ran upstairs and enters her bedroom. She sees Damon sitting on her bed. She shuts the door behind her.) I thought we were clear about this." Margaret said

"I'm just doing my part in the neighborhood watch. Trusty bodyguard. Calm in crisis." Damon said

"Have you been drinking? (Damon holds his forefinger and thumb a small distance apart, indicating that he has been drinking a little.) You're drunk and upset. That can't be good." Margaret said

"No, I'm not upset. Upset is an emotion specific to those who care." Damon said

"That's a lie. You do care." Margaret said

Damon looks up at Margaret.

"You're surprised that I thought you would have feelings for me? That what we've been doing here means something? You're the liar, Margaret. There is something going on between the two of us and you know it. (Damon get's up and walks towards Margaret.) You're lying to me, you're lying to everyone that you care about, and, most of all, you're lying to yourself. I can prove it." Damon said

"Damon! (Damon quickly grabs Margaret's face in his hands and kisses her with a passionate kiss. She wanted to stop but couldn't resist. Someone knocked on the door and both of them stopped kissing. Damon disappeared.) Come in!" Margaret said

Elena open the door.

"I'm just checking in. Making sure everything is ok." Elena said

"Yeah." Margaret said

Margaret all nervous.

"With Damon's obsession with you..." Elena said as her sister interrupted her sentence

"Elena! There's a lot going on right now. Katherine being here. Her pretending to be you. We have to stay on point, ok?" Margaret said

"Ok. Night." Elena said

"Night." Margaret said

Elena closes the door. Margaret looked at her window and saw Damon down on the ground. They looked at each other she waved at him and he waved back. He disappeared.
