Sorry I really hated the first chapter so I had to redo it and I promise an update is coming!

Chapter One: JJ's POV

They were in their own backyard. D.C. had a killer on their hands, and he was one the B.A.U wouldn't be forgetting in the near future. He murdered and molested children but these children hadn't been reported missing anywhere in the country; they weren't in any foster system or orphanage. They simply did not exist. Well not until Spencer stumbled across a no doubt unbelievably strange, but true, theory. These children were adults. The tox reports showed high signs of Plorbic Acid and Arsenic. Arsenic is poisonous but the Plorbic Acid kept them from dieing for weeks. This combination shortened the strings of DNA within the nucleus and Pressdo! They were children. Garcia found a report of large quantities of Arsenic and Pluotonium that were stolen from the local biochem lab. With no survilence footage you would think we were hooped, but no the ever resourceful BAU came to a magnificant conclusion: you still need hydrogen to make Plorbic acid. A small amount had been delivered to Mr. Whitley; a registered sex offender.

"JJ, Emily, Rossi hit the house on Pineveiw. Reid, Morgan come with me; we're taking the warehouse." It took us mere seconds to follow Hotch's commands.

Emily, Rossi and I were in one SUVs heading north and Reid, Morgan and Hotch were going south in the other. The ride there was silent; the case had hit us all pretty hard. The ones with children always did.

A few seconds before pulling up Rossi said "Emily you take the front and JJ and I will go around the back and wait. The pedos always try to escape; you probably won't even make contact with him."

Emily nodded as the tires crunched too loudly on the drive. I closed my door quietly as Rossi and I snuck around the back; our guns drawn. We waited; it would only take a minute or two for him to get out here if he wasn't in the warehouse.

I shot Rossi a worried look it had been three minutes without any radio contact from her.

"Emily?" My voice crackled over the radio. No answer, no yell of 'it's clear'.

"Emily" Rossi tried. Nothing. I looked over at him; he nodded. We walked in from the back with our weapons out.

"Robert Whitley?" Rossi called out.

"FBI" I added. I heard a faint scuffle. Rossi and I advanced to the bedroom.

He was opening the window; about to jump out. "Robert" Rossi said "You don't want to jump, we're three stories up, you'll die."

He chuckled a manic laugh. "I guess you need me to help your friend, right? You want an antidote." I turned to vision to the floor at the same time Rossi did.

There lie Emily Prentiss. Well a teenager in her clothes anyways. I heard myself gasp. He smilied at that.

"The little bitch pulled the needle out before I was done. She only got a half dose." He was enjoying this; the looks of horror on our usually well composed faces.

"Come on Robert just step off the window sill and we can talk." Rossi's voice was calm and smooth. I could tell, though, on the inside his blood was boiling.

"I'm afraid I can't do that agent." He reached for the gun at his hip just a bit too late. The shot hit him square in the head. One shot, one kill. My hands were shaking as I lowered my weapon that had been fired just seconds before.

The medics were called by Rossi as was Hotch; who was currently making his way here. I knelt by Emily's body. She was smaller and thinner than her adult self when I wrapped my arms around her unconscious form.

The medics loaded her into the ambulance as Hotch, Reid and Morgan arrived. Eleven months ago she was in an ambulance riding to her death. Morgan and Reid were understandably distrustful of her whereabouts as we all drove to the hospital.

The hard plastic chairs were uncomfortable as we lie in wait of news on her condition.

"I still don't understand how that's possible!" Reid exclaimed.

"Ya, well it happened." I snapped. I saw the hurt look on his face. "Sorry" I mumbled.

He shrugged "It's fine."

"Emily Prentiss?" A doctor questioned; we all stood up waiting to hear her fate.
