Sorry it took so long to update... I kind of got sidetracked by a burst of fnafic-creativity revolving around Battlestar galactica and didn't have a chance to post this chapter until now... I hope you like it...

As always... reviews a not only welcomed they are necessary!

Part 6

Tom hurried down the hall to Lexa Morgan's hospital room knowing he was already late. He took a quick glance at his watch half an hour late he thought to himself at least I have a good reason. Hopefully Agent Stevens hadn't had enough time to do any serious damage yet

They have been there almost constantly for the past 4 days, talking to Lexa, getting details on the killer's memories, trying to put together something that would narrow down the search. Lexa had been extremely cooperative; she answered all their questions over and over again, she allowed them to conduct every medical test they wanted - Cranial CT, MRI, Brainwave monitors, blood tests. It seemed that whatever Shawn said to her that day really did the trick. But after 4 days they were all getting tiered and edgy - especially Lexa, and Agent Stevens making a point out of pushing her and harassing her was not helping at all.

Sure enough by the time he walked into the room, Lexa and Agent Stevens were already going head to head.

"So let me recap what we have so far" Agent Stevens was circling Lexa like a vulture while she watched him with trepidation "You say his name is John or Jonathan, he's white and tall - but you can't tell me exactly what he looks like. He works alone, but you don't know what he actually does. He lives alone but you don't know if he's ever been married. You say he owns a house with a front yard but you can't give me an address, and he drives a pickup truck that has a dent on the passenger side from a fender-bender about 2 years ago, but you can't tell me when or where this accident happened… And here is my favorite part: he always wanted to get a dog but never did and his mother made him take piano lessons as a child" he stopped circling and threw his hands up in a mock melodramatic gesture "What am I supposed to do with that? Do you know how many men fit that description?"

His tone was accusing and challenging and Tom could see the expression on Lexa's face change from fear to anger with every word spoken.

"You know, this isn't exactly hard science Agent Stevens!" she glared at him "I'm lost inside some guy's brain and it's like a freaking maze in there. Sometimes I'm in there for 10 minutes sometimes I'm there for 3 seconds and half the time the things I'm seeing are not exactly the kind of things you want to pay attention to. What do you want from me? His social security number?"

"It wouldn't hurt!" Agent Stevens' retort came with a slick smile and Tom could sense that Lexa was just about to lung at the man.

Luckily, Diana stepped in to referee, sending both Lexa and Agent Stevens back to their corners "Why don't we all just take a break for a minute"

When the scene seemed to quiet down, Tom took the opportunity to give Diana a small signal and the two of them stepped out of the room for a moment.

"Where have you been?" she asked him with frustration as soon as the door closed behind them "The guy has been on her case all morning. I wouldn't be surprised if she tries to take a swing at him pretty soon…"

"We got a lead on the Collier case…" He told her and she noticed for the first time how excited he seemed, practically jumping on the balls of his feet "You're going to love this…"

"Well, What is it?"

"The lab found trace evidence on the jacket we found in the ally. First of all, they found some hairs with DNA matching the DNA we have on file for Jordan Collier…"

"Why do I have the feeling there's more?" she gave him a small smile

"They found traces of soil, sand to be exact, and they managed to trace it back to a specific location. Turns out - at some point, probably recently, Jordan Collier was at the return site"

"The return site? You mean the same location where the whole "call of light, 4400 people appearing out of thin air" thing happened?"

"That's the spot!"

Shawn woke up slowly and stretched in his bed. The soft morning light poured through the windows of his bedroom indicating a beautiful morning outside. He rolled over and nearly screamed in surprise at seeing Isabelle sitting on the edge of his bed, looking at him intently.

"Isabelle what are you doing here?" he pulled the covers up to his chin, covering his bare chest and wishing he wore more then just boxers to bed the previous night "How did you get in here?"

"I came in through the front door" she frowned at him as if not understanding the question.

"I'm pretty sure I locked the front door Isabelle!" he tried to admonish her, knowing even as he was doing so the it would not do any good "How long have you been here?"

"Not long" she shrugged "I needed you - it's about Dr. Burkhoff"

"What about him?" Shawn felt a desperate need to put some clothes on but just couldn't do anything while Isabelle was there - watching him.

"He's acting really weird"

"You mean more weird the usual?" Shawn said tiredly, Wondering if Isabelle was just making up some excuse so she could creep into his bedroom and catch him off guard.

But Isabelle nodded and smiled "Way weirder then usual! You better come see for yourself!"

She looked at him for a long moment, as if expecting him to move. Finally he just had to come out and say it "Isabelle, if you want me to go anywhere, you're going to have to wait outside while I get dressed!"

15 minutes later Shawn was riding the elevator down with Isabelle by his side. He still felt unbelievably uncomfortable about the whole exchange that took place in his bedroom merely moments before - but Isabelle didn't even seem to notice.

"I came to see Dr. Burkhoff this morning for my check-up - you know, he's been running all these tests on me ever since I grew up…" Shawn almost laughed out loud at the simplicity of that description as they stepped off the elevator and headed for the lab "And his lab is a mess - and you know what a neat freak he is! And he's standing there' just talking all this gibberish, acting really weird…here, you see for yourself"

She opened the door to the lab and the two of them walked in. Shawn took one look around the lab and realized immediately what Isabelle was talking about.

The usually neat space looked like a Tornado had gone through it. There were dozen of books and computer printouts all around the floor. Dozens of half empty food cartons were lying around on every available surface. Test tubes and syringes were discarded everywhere, some of them of them spilling their content on pages and pages of D. Burkhoff's precious research.

The man himself was at the other end of the room, mumbling to himself, mixing some ingredients over a buton heater, flipping through pages over fresh computer printout at a frantic pace.

"Dr. Burkoff?" Shawn asked gently, fearing the man had finally gone over the deep end.

"Can't talk! Can't talk now Mr. Farrell!" The doctor called back over his shoulder, his voice still carrying that jittery quality it always has "Have a lot to do! A lot to do! Can't talk!"

Shawn glanced at Isabelle for help but she simply shrugged, giving him a helpless and somewhat amused smile. He took a few steps, careful not to step on anything important, and closed the distance between his and the doctor asking him again if everything was alright.

"Yes, yes. I'm fine! In fact I've never been better!" The doctor replied, finally glancing up from his work.

Shawn frowned, still not convinced, but then Isabelle stepped in and placed a hand on his shoulder "He took the promysen Shawn… he injested it to himself…"

Shawn stared at the doctor with a look of utter shock "You did what?"

"I had too, I had to test it on myself. I had to examine to effects it has on normal human beings in order to fully comprehend the process the 4400 underwent…"

"He has his ability now Shawn" Isabelle continued calmly "Don't you doctor? You can see things, calculations, answers to mathematical problems… you see them in your head…"

"It's amazing!" the doctor said excitedly "I've never felt more alive before in my entire life…"

A/N: I'm having tons of fun writing old Isabelle in this story... I know there's a lot of theories on her being good or evil, haven't really decided which way I'm going to take yet... but for now I'm kind of writing Isabelle the way I think any kid would be if he would suddenly age 15 years - totally oblivious to right or wrong or common manners and politeness... you know? like she doesn't mean to make people uncomfortable but she just doesn't have all the social bounderies normal people have...
