At the high school, everyone was outside working on the floats for the parade. Bonnie was inside, going through Emily's spell book. Elena agreed to meet her there and was running a little late. "Sorry, Caroline held me up."

"No problem. I wanted you to see this."

"Is that Emily's spell book?" Elena asked.

"Yeah, I've been going through it for a while." Bonnie said. "Check this out." Elena sat down next to her and noticed a familiar looking item sketched in.

"That's the vampire compass." Elena realized. Right now, it was safely hidden in Jeremy's room. She knew because they'd made sure of it.

"According to Emily, Jonathan Gilbert never actually succeeded in inventing anything. Emily secretly spelled them all with magic." Bonnie explained. "Compass, rings and the mystery device you told me about."

"Wow." Elena said. Bonnie showed her the page with the device on it. "That's it."

"Emily pledged her loyalty to Katherine. But she couldn't stand by and watch innocent people get killed. This was the only way she could think of to help. To let Jonathan Gilbert believe that he'd actually invented these devices."

"So, what does this thing do?" Elena asked. Bonnie looked to her, with concern on her face.

"Are you sure this is what Isobel wants?" Bonnie asked her.

"Yeah, I'm sure. Why?" Elena asked.

"This is a weapon. Against vampires." Bonnie explained. Elena looked at her in shock.

"So if this goes off…we risk putting ourselves in danger." The girls looked at each other, both worried.

Outside the school, Elena found Jeremy outside. "You okay?"

"Yeah. Have you seen Stefan around here?" Elena asked. "I need to talk to him."

"No, I haven't seen him." Jeremy told her. "Do you have a second?"

"Yeah. I know what the device does, and it's not good."

"You haven't seen Anna around lately, have you? I've been calling her for days, but she hasn't called back."

"I'm sure that Anna's okay, Jeremy." Elena told him. "Besides, she's a good friend."

"We're more than friends, actually." Jeremy explained. "So, what's wrong? With this device?"

"It's spelled to work against us, Jer."

"You mean…vampires?"

"Yeah. We saw it in Emily's spell book." Elena told him.

"Now I'm even more worried about her." Jeremy said. "I'll try to warn her, I just hope she picks up."

"Jeremy, watch yourself out there." Elena told him. He nodded and took off. She turned around and found Isobel behind her.

"Isobel. What are you doing here?" Elena asked.

"I'm your mother, Elena. I want to be more involved in your life." Isobel told her.

"I don't want you in my life." Elena pointed out.

"I understand that. You already have a lot of people that you care about but I've been studying." Isobel said. "Let's see if I got this right. There is the witchy best friend, Bonnie. Gonna stay away from that one. And there's you're pathetic human boyfriend. And there's Caroline… obnoxious Caroline. I got all of my info from her by the way. She had no idea who I was and she wouldn't stop yapping. Oh…And there's Matt, friend, ex, yappy's future ex. Lots of connection there."

"Matt is not involved in this." Elena told her.

"He's involved with you, isn't he?" Isobel pointed out.

"Look, you shouldn't be here. You need to leave."

"No, I have some friends here too. Look, you see that man over here, standing next to Matt by the float? His name is Frank, he's very handsome and he's also quite handy and he'd noticed that the axles are a little rusty which is very dangerous." Isobel said. "So, all you have to do is apply a little bit of pressure and…"

"No!" Elena watched as the trailer collapsed on Matt. She tried to run, but Isobel grabbed her.

"Get this trailer! Come on guys help me!" Matt called. Tyler, Caroline, the football team, Stefan, and Jeremy ran over and got the trailer off of him.

"Call an ambulance." Stefan told Caroline.

"Why are you doing this?" Elena asked.

"I'm showing you how easy it is to hurt the people that you care about." Isobel said.

"And you're doing this just because of Jonathan Gilbert's invention?" Elena asked.

"Hand it over and it will stop."

"I told you, Damon is not going to give it to me." Elena pointed out.

"I think that you underestimate how much Damon cares about you."

"Please, he'd kill both of us first." Elena said.

"Fine. Guess I'll have to talk with my ex again."

The group met in Ric's classroom. "Where is the device?" Bonnie asked.

"Damon has it. He's going to be difficult to reason with." Stefan said.

"We'll go to him, I'll talk to him." Elena said.

"I don't know, isn't it like suicide if we hand it over?" Jeremy asked.

"It's suicide either way, Jer. He's threatened Alaric." Elena pointed out. She turned to Stefan. He seemed hesitant to answer.

"I know my brother, and he'd want to keep this town safe." Elena remembered something then.

"I think I know a way to prevent us from getting caught." She told them.

"Are you sure about this?" Damon asked. The group met up in the Boarding House.

"I'm sure." Elena said.

"If you give this to Isobel, you realize you're putting yourself in danger."

"That's why Jeremy and I will be nowhere near the Founder's events." Elena said. "But the rest of the tomb vampires are still out there, maybe this will finally get rid of them."

"What if you don't make it out in time?"

"She will." Bonnie said. "I trust her."

"And our secret will still be safe." Elena said.

"Besides, if we don't do this, we're still putting the whole town in danger." Jeremy pointed out.

"I think this plan will work, hopefully before Isobel starts killing people." Stefan said.

"And you're sure that they'll make it out okay?" Damon asked Bonnie.

"Of course." Bonnie said. "Elena's my best friend and even though things have been hard lately, I will always trust her."

"The same goes for me."

"And me." Damon handed the device to Elena. Just then, Jeremy received a message.

"Jeremy?"

"I've gotta go. She got to Uncle John." Jeremy said. "Good luck." He left the room.

At home, Jeremy found John on the floor. "You okay?"

"Yeah, took me by surprise though."

"What happened?"

"We've been looking for a weapon that's harmful to vampires." John explained. "We've been trying to get it."

"Why would a vampire help you kill other vampires?" Jeremy asked, then realized how stupid the question was, since he and his sister were trying to get rid of the tomb vampires, too.

"She has her own reasons for wanting them dead." John said. "Look Jeremy, no one ever thought vampires would return to this town. Not in modern times, but they have and we have to destroy them."

"All of them?" Jeremy asked. He showed no emotion, but he was still pretty worried. "What if there were good ones out there?"

"There's no such thing." John told him.

"I don't believe that." Jeremy said. "In fact, that sounds really stupid."

"Well, your dad did. And has his son that should mean something to you." John said.

"Well, my father may have thought differently." Jeremy said. "Besides, what makes vampires any less evil than humans?" He asked him. John watched in surprise as he left the room.

At the Boarding House, Bonnie was doing a spell on the device. This was part of their plan. When the Founder's activated the device, the spell would alert her so that she could tell Elena and Jeremy to run if they weren't out in time. "Okay. We're ready." She told them, handing the device to Elena.

"So, ready?' Damon asked.

"Let's get this over with." Elena said.

In town, Elena was waiting for Isobel to show up. The rest of the group was hiding nearby, in case she tried anything. She turned around, knowing Isobel was behind her.

"Where's the device?" Isobel asked.

"Where's my brother?" Elena countered.

"Relax, I didn't go anywhere near him."

"She's telling the truth." She heard Jeremy answer from a distance.

"Did you think I came here alone?" Isobel asked. At that moment, her henchmen appeared behind Elena. She didn't even turn around.

"I'm not alone, either." Elena said. As if on cue, Bonnie, Damon, and Stefan appeared behind Isobel.

"Impressive." Isobel said. "But you can't save everyone, you know."

"How did you know Damon would give me the device?" Elena asked.

"Because I knew he would put the town over his friends." Isobel explained. "His problem is that he's too soft."

"Don't listen to her." Bonnie whispered to them. "She's just trying to get to you." Elena handed the device to Isobel.

"Thank you." Elena said as Isobel turned to go.

"For what?" Isobel asked.

"For being such a monumental disappointment. It keeps the memory of my real mother perfectly intact." Elena told her.

"Goodbye, Elena." Isobel said. "As long as you have a Salvatore on each arm, you're doomed. Katherine was smart. She got out. But we all know that you're not Katherine." She left.

Elena was shaking by the time she was gone. She felt Stefan's arms around her. Someone else touched her back. "Come on." Bonnie said. "Let's get you out of here." Elena looked and saw that Damon had left.

Jeremy was up in his room, waiting to hear from Anna or Elena. He was relieved when his sister returned. "Hopefully she'll leave us alone now."

"Yeah. You really think this plan will work?"

"It has to." Elena said. "Have you heard anything from Anna yet?"

"No, nothing."

"Think she's okay?" Elena asked.

"I hope so." Jeremy told her. "I left her a message about the plan, but I don't know if she's with us. She doesn't really trust the humans much."

"You two are really close, aren't you?" Elena asked.

"We're practically dating." Jeremy told her. She looked at him, surprised.

"Jer, we'll all get through this."

"I know, but I still think we should keep a low profile." Elena nodded and left the room. Jeremy headed back to his bed, when Anna suddenly showed up.

"There you are. I've been worried about you." Jeremy said.

"My mother's dead." Anna told him. She looked really upset.

"What?"

"Your uncle…he killed her. She said she was meeting him yesterday."

"I am so sorry." Jeremy said. "I'll kick his ass for you." She laughed a little.

"Thanks. I know I shouldn't be here, but there's nowhere else for me to go." Anna said. Jeremy walked over to her and held her.

"It's okay. I'll make sure he doesn't hurt you."

At the Boarding House, Stefan entered the room to find Damon. "You're not upset because of what Isobel said, are you?"

"What do you mean?"

"That you'd always put the safety of the town over you're friends." Stefan said. "We both know that's not true."

"No, the thing is, she's right." Damon said.

"Damon…"

"Just listen for a second. If I had the option, I'd put the safety of others before the safety of our friends." Damon told him.

"I can understand that." Stefan said. "But if you ever do anything to hurt Elena or Jeremy, I'll kill you myself."

"If you want to protect them, I think there's something you should know." Damon said.

"What is it?"

"Isobel said she dated John in high school." Damon explained. "What if she got pregnant when she ran away?"

"And Jenna told Elena that she ended up at her father's office." Stefan said, catching on. "Are you suggesting that John's her real father? Are you sure?"

"I'm not sure of anything these days, Stefan. But who else could it be?" Damon pointed out. He left the room, leaving Stefan in shock.

At the Grill, Bonnie was with Caroline. "You okay?"

"Look, Elena wants me to do something tomorrow, but I'm worried that it might be putting her in danger."

"Hey, I know that you'll find a way to save her. You always find a way, Bonnie."

"You're right, Caroline." Bonnie said. "I'll see you tomorrow." She got up and left. This plan had better work or we're all in trouble, she thought as she headed to her car.
