It can't be

"What is wrong with her?" Derek asked deaton.

"I don't know derek. I've never seen something like that before." Deaton replied

"Well there's gotta be something that we can do for her." Stiles said.

"I'm afraid there's nothing we can do for her." Deaton said calmly

"May be we need to think from a different angle." Stiles said and Scott looked at him.

"Stiles I know that look" scott smiled.

"What look?" Issac asked.

"I have a plan look." Scott said.

"Good going stiles. So how do we kill her? Drown her, poison her, rip her throat open. I've got a lot of options ." Erica said and derek slapped her.

"Derek. You are loosing your control." Boyd said and picked up Erica.

"Enough. My plan does not include killing Em. " stiles yelled.

"What you got stiles?" Scott asked.

"Jenna must know about Em.  And I know that she doesn't want anyone to find out." Stiles paused.

"Jenna once told me that Em is not the same person after her brother's death.  May be whatever power she have was in control of her but after her brother's death she can't control it anymore ." Stiles said.

"This can be possible." Deaton said.

"Good work stiles." He added

"So how do we get the truth out of her aunt. I'm assuming she won't tell us something like this." Lydia said.

"Guys jenna is calling me." Stiles said.

"Hello. Hi jenna" stiles said.

"Where's Em? Bring her home." Jenna told stiles.

"Well she's kind of resting right now. "Stiles replied.

"Stiles where is she?" Jenna shouted at stiles.

"Derek 's loft." Stiles panicked.

"I'm sending someone to get her." Jenna hung up on him.

"OK.  We might have a problem. " stiles said.

"You think. " Jackson comments.

"We can't let her take Em back." Scott said.

"Scott she is her aunt. You can't stop her." Allison said.

"Well hello there. " someone said.

"How the he'll we didn't notice him?" Jackson said suspecially.

"Jenna suspected that Em would be here. So she already send me this address way before calling you." That person said coldly.

"She's resting." Scott said.

"I'm taking her with me." That person picked up Em in bridal style.

"you can't do this." Issac protests.

"Watch me." He replied and within few seconds he was gone with Em.

Third person POV

It was always my responsibility to protect you Em.  But I failed you. I thought getting out of your life will keep you safe. Letting you go was the hardest decision that I made. All your life you were unloved . You deserve better then this. I promised myself that I will keep you safe and happy. I never knew that my demons will hunt you down.  It's time for me to to set things right.

"I have seen that guy somewhere. " Scott said

"What do you mean?" Derek asked

"I can't remember. " Scott sigh.

"It can't be. " stiles whispered.

"What can't be?" Issac said

"It was Damon.  Her dead brother." Stiles said and derek was full of anger.

"No way. He died." Allison said.

"He faked his own death. But why?" Lydia said.

"We have to get Em.  Before his so not dead brother do something. " stiles suggest.
