Elena walked into the kitchen to find John bleeding on the floor. She sped to his side immediately. "How can I help?" She asked. She knew he didn't trust vampires, so she was being careful. He was barely responsive, so she called the hospital. It wasn't until then she heard him whisper something.

"What?" She asked him.

"Behind you!" He managed. Elena turned around, but didn't see anyone there. She headed into the hallway, picking up a knife just in case. She heard something speed behind her and turned around. Then she heard the front door open and close.

"Jeremy." She sped upstairs and burst into his room. "Jeremy?!" She called, panicking for a moment.

"Elena?" Jeremy got up from his bed. "What's wrong?"

A few minutes later, John was being taken away in an ambulance. Stefan had shown up. "He's fine." Elena told them. They both headed back up to Jeremy's room.

"What's going on? I called my brother, but he was busy with the sheriff."

"Someone else was here a few minutes ago, but they ran out before I could catch them." Elena explained. "It had to have been another vampire."

"And you didn't see them?"

"No, but I heard the door open. I assumed it was Elena." Jeremy explained. He seemed like he had other things on his mind.

"What should we do?"

"Is there anyway to keep a vampire from entering?" Stefan asked.

"Not if they've already been invited in." Jeremy said.

"Are you okay, Jeremy? You seem kind of down." Elena said.

"I'm worried about Anna." Jeremy told her. "Her burns aren't healing. Look at this." He showed them the small burn he still had on his wrist. It looked better, but still hadn't fully healed.

"Well, we should wait until the vervain's out of her system."

"I don't know, they used a lot of vervain. Even Jeremy's still not fully recovered." Elena said. "But I'm sure she'll be okay. She's a lot older than us, so it shouldn't effect her as much."

They headed into the hallway. "You should go make sure John's okay." Stefan said. "I'll wait here with Jeremy."

"You don't have to…"

"Look, you shouldn't be here alone, Jer." Elena said. "It's a good idea, in case they come back."

Meanwhile, in the waiting room, Bonnie entered to find Matt and Vicki sitting together. "How's Caroline?" She asked.

"She's not good, Bon." Matt said.

"What happened?"

"We were driving and Tyler heard this noise and then…"

"A noise?" Bonnie asked.

"I was so scared that one of us could've gotten hurt." Vicki said. "And now Caroline…this is just awful."

"He lost control of the car." Matt said. "She was fine one minute, but then she fainted."

At the hospital, Damon walked over to Sheriff Forbes. "Liz, I came as soon as I got the message. Is she okay?"

"She's in surgery, it's ... they're doing everything they can." She explained. "I need your help Damon."

"Sure, anything Liz."

"Mayor Lockwood is dead. They thought he was a vampire. They put him in the basement." Liz told him. "It was a mistake, they said he dropped like the others when John's device when off but he… he couldn't have been a vampire, I've known him my whole life and know Carol Lockwood is gonna want answers and all I can think of right now is Caroline and ..." She started crying.

"Hey, it'll be okay." Damon told her. He held her, worried about his friend and partner.

Downstairs, Elena met with Bonnie. "How's Caroline?"

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

"What?" Bonnie hugged her friend.

"Is there something that we can do? Like a spell or something?" Elena asked.

"She doesn't know it." She turned around and saw Damon had entered the room. "Do you?"

"No, I don't."

"Even Emily had trouble learning that one." Damon told her.

"There is a way we can save her, but I know you won't like it." Bonnie said. She looked at Elena.

"Oh, no. There's no way." She said.

"What if you only gave her enough to heal her? It'd pass out of her system within a day." Damon said.

"It's too risky, you guys. What if something happens?" Elena asked.

"Elena, it's Caroline." Bonnie pointed out.

"Okay, I'll do it for her." Elena said.

"I'm going to check on Vicki. She's a nervous wreck and the added stress isn't helping Matt." Bonnie told them. She left.

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

"Yeah, one of the tomb vampires got into to house and almost killed John." Elena told him.

"What? When? After I left?" The question stunned her.

"You were there?" Elena asked him.

"Yeah, we were outside together."

"Damon, I never saw you at the house." Elena said. "I'd know if you'd been there."

"I know I saw you, though." Damon said. The two of them looked at each other, confused at what was going on. Just then, Jenna showed up.

"Elena, I came as soon as I get you message. How is John?" Jenna asked.

"Where have you been?" Elena asked her.

"At the fire department, I deferred a report. I told you earlier." Jenna said.

"No, you didn't." Elena said, feeling even more confused.

"Yes, I did."

"No, Jenna, you didn't."

That was when he realized it. "Oh, now I get it."

"Good, can you explain it to us?" Elena asked.

Back at Elena's, Stefan was with Jeremy when they heard the front door open. They headed downstairs. Jeremy stayed in the hallway.

"Hey, how's Caroline?" Stefan asked.

"Not good." Elena told him. She stepped into his arms. He felt something was off with her. She leaned in to kiss him, but he pushed her to the floor.

"What are you doing?" Jeremy said, rushing in

"It's not her, Jer." Stefan told him.

"At least I fooled one of you." Katherine said, getting up. Just then, the door started to open. Katherine threw Stefan to the floor. "Sorry about that, but I gotta run." She disappeared after that.

Elena and Damon walked in just as Jeremy helped Stefan up. "Whoa. What happened?" Elena asked. The guys looked at each other.

"Katherine happened." Damon said. She looked at them.

A few minutes later, the Salvatores were talking in the kitchen while Jeremy told Elena explained what happened a few minutes before she arrived. "Did she say what she wanted?" Damon asked.

"No, of course not. It's Katherine." Stefan pointed out.

"Well, she knows how to make an entrance, that's for sure."

"She said she fooled one of us." Stefan pointed out.

"She pretended to be Elena when I showed up earlier tonight." Damon explained.

"Jeremy told me what happened. Are you okay?" Elena asked.

"I'm fine, but how are you doing with all this?" Stefan asked her.

"I thought with the tomb vampires gone, things would get better." Elena said.

"So did I." Jeremy agreed, entering the room.

"Katherine's been invited in." Elena said. "What are we going to do?"

"Well, she can't get into our place."

"And just leave Jenna to deal with her?" Elena pointed out. "No thank you."

"Well, at least we know she's a vampire now. But if she wanted you dead, she would've tried to kill you already." Damon said. "She always had intense thoughts, like dying young."

"Looks like she already accomplished that, sort of." Jeremy said.

"For now, let's find out what she's up to and try not to provoke her." Stefan said. He turned to Damon. "What happened tonight when you thought she was Elena?"

"We were talking, and then she kissed me." He told them.

"You thought that was me?" Elena said, feeling offended and repulsed. Jeremy and Stefan looked at each other.

"I'm glad it wasn't. I could never do that to my brother." Damon said. "Not after last time."

"There needs to be something we can find out." Stefan said.

"Maybe John knows something. I mean, Katherine tried to kill him." Elena pointed out.

"Might want to be careful about that. She loves to play games and it's difficult to find out what she's up to before she wants you to know." Damon said.

"She's right, though." Stefan said. "John could know something through Isobel."

"That's right, with everything going on, I completely forgot about that." Jeremy said. "Your birth mom was in touch with Katherine. Maybe we should pay John a visit."

"We better keep our guard up." Damon said. "You never know when Katherine will decide to make a move."

At the hospital, Bonnie, Matt, and Vicki met in the hallway. "You've been here all night?" Bonnie asked.

"Yeah, with the Sheriff." Matt said.

"He's still really worried about Caroline." Vicki explained. "I left to call and see how Tyler was doing."

"So, no one else was here?" Bonnie asked.

"I thought I saw Elena on my way out." Vicki said.

"How's Caroline?"

"See for yourself." Matt said. They entered Caroline's room. She was awake and seemed to be feeling better.

"Hey, guys." Bonnie hugged her. She was grateful that Elena had decided to heal her, since she was a little behind on her magic practice lately.

"Careful, still a little sore."

"Sorry."

"They say I'm healing quickly." Caroline said.

"My turn." Matt said. He kissed her.

"I got these to help brighten the room here. You seem to be feeling better, though." Vicki said, setting a bouquet down on the table.

"Yeah, I'm doing really good." Caroline said. She noticed tears in Bonnie's eyes. "Why are you crying?"

"I'm just happy you're okay."

"Oh, I love you guys!"

"We love you, too." Bonnie and Matt hugged her. Vicki smiled at the group.

"Vic, get in here." Matt said.

"Uh, this is more you're thing…"

"Oh, come on." Caroline said. Matt pulled his sister in, anyway.

At the Lockwood house, Damon and the Sheriff were talking with Mrs. Lockwood. "I want to know exactly who's responsible for killing my husband."

"I'm looking into it but you have to be straight. Is there any reason Richard was affected by the vampire device?" Liz asked her.

"Are you implying that he was one of them?"

"No, no one's implying anything." Damon told her. He found it strange that a non-vampire had been effected by the device though.

"Your deputies screwed up, plain and simple which makes you responsible." Mrs. Lockwood said.

"Carol..."

"Your husband is the one who helped John Gilbert execute his idiot plan in the first place." Liz pointed out.

"Someone got my husband killed."

"Okay, we're all on edge here." Damon said, trying to keep things from getting even more ugly. "You've suffered a great loss, the whole town has. We've got to stick together, trust each other." He pointed out. "We'll get through this." The group looked at each other.

"How's your daughter?" Carol asked.

"She's doing better. And Tyler?"

"I haven't seen him since I told him about his dad."

Elena and Jeremy went into the hospital. "Ready?" Elena nodded. The went into John's room.

"John?" Elena asked. He looked at them and seemed startled to see Elena. "It's okay, I'm Elena, not Katherine."

"We know she's the one who did this." Jeremy said.

"Why did she attack you?"

"Where is she?" John asked them.

"We don't know." Elena said.

"Neither do I." He winced.

"Easy, Uncle John." Jeremy said, coming to his side.

"Do you know why she's here?" Elena asked. "What she's after?"

"You need to tell us what you know. She can always attack again." Jeremy pointed out.

"I don't know anything." John said. "She never trusted me, she never said anything apart from getting rid of the tomb vampires."

"Well, at least that gives us something to go on." Elena said. She left the room.

"Look, I know you probably still can't stand what we are," Jeremy said. "But not all of us are the bad guys here. Thanks to you, Anna's still hurt and if you ever try to hurt her or Elena or me again, I'll turn you myself." He left the room.

At the Lockwood's, most of the town had shown up already. Damon noticed a guy talking with Carol and went over to Liz. "Who's the guy with Carol?"

"It's the mayor's younger brother, Mason Lockwood." Liz told him.

"Is he on the Council?"

"No. He's not a believer. He wants nothing to do with the council. He's too preoccupied finding the perfect wave." She explained.

"I see."

Tyler went over to the door to greet Elena. "Hey, Elena. thanks for coming, come on in." Katherine entered the house, smiling.
