Sam sat on the couch in Tom's living room awkwardly. It didn't feel right being here.

It turned out Tom was discharged about half an hour after Sam was, and following Charlie telling him that Sam had discharged herself he had ran the 2 miles between both hospitals so he could offer her a place to stay. Sam had reluctantly accepted, unsure about staying with someone she technically barely knew.

The conversation in the taxi back home had been all about Sam's theories as to who could have planted a bomb in the ED, and having Tom around proved an asset as he knew everyone's names and could tell Sam a bit about each person that passed through the ED. Unfortunately this gleamed her no new information. It wasn't until they returned home that something Tom said became useful.

"Do you want to watch the TV?" Tom asked, pointed at the flat screen in front of them after he sat down.

"No. But I was wondering if you could tell me anything else about the people who pass through the ED, like what about the patients that day? Were there any acting suspiciously?"

"Not as far as I could tell… and everyone who went into recess that day was unconscious, and all their possessions were stored else ware so it was unlikely any of them had a bomb."Tom replied with a frown. "Though…"

"Though what?" Sam asked as she stared at him eagerly.

"There was something a bit odd about you in the days leading up to the explosion." Tom said slowly, as though he was unsure of whether or not he should continue.

Sam felt a cold shudder run down her spine. "Something odd... about me?"

"Yeah...come to think of it you were being kind of secretive, like you had something to hide. I always saw you talking to someone on your break and I saw you leave the ED with them sometimes when you were supposed to be working?"

"Did you see who I was with?" Sam asked while sitting up a little straighter and hoping the conversation wasn't going the way she thought it was going.

"I never saw his face...but he was wearing a lab coat," Tom replied as realization dawned on him, "You don't think it was…"

"Mark James? Sounds like it. That would explain why he said my name when he came through the doors..." Sam said slowly.

"But what connection would you have to him?" Tom asked as he studied her face.

"From what I understood he couldn't have planted the bomb, he'd be dead, and all I have to go on is a vague memory of either chasing after him or running with him towards the ED doors and then me running back the other way after looking through the doors and a massive exploding sound coming from behind me." Sam said, staring at her lap as she concentrated on the flashback.

Tom's frowned deepened. "But he could have made the bomb."

"Yeah…" Sam agreed, "But I don't think he did."

"What makes you say that?" Tom asked, staring at her in surprise.

"I don't know… It's just a feeling I've got. I think know who made the bomb, or I did before I lost my memory." Sam replied.

"So if we find a way to bring your memory back then we may have an answer to all of this. But... what if you're connected?" Tom asked, giving her a look of concern.

"Then I turn myself in," Sam said firmly, "A lot of people were seriously injured or killed in that explosion, if I had any part of that then I don't deserve to have a life."

Tom stood up for a moment and stared at the TV, his eyes apparently transfixed on a tiny speck of dust that had landed on the screen.

"You ok sleeping on the couch? You're sitting on a blanket and it's getting late. Time for some rest." Tom said tonelessly before walking out of the room.

Sam followed the sound of him stomping upstairs and slamming the door before letting out a breath she wasn't aware she had been holding. She then stood up and picked up the blue blanket she was sitting on, before removing her jacket and folding it into a makeshift pillow before settling down to sleep.

Sam was running as fast as she could towards the ED with Mark, who was slightly ahead of her. As soon as they burst through the ED entrance they both headed straight for recess.

Sam saw mark pull out the thing they had been working on together from his pocket and run through the double doors. The thing was blurred out in her dream, as though her mind didn't want her to see it.

Sam looked through the ED doors and saw Mark kneeling down on the ground right next to the doors and fiddling with something, before motioning Sam to run away as he stood up and followed suit.

The resulting explosion knocked the air out of Sam and propelled her into a nearby wall, and everything went black.

"Sam! SAM! Wake up, you're having a bad dream!"

Sam opened her eyes. She was on the floor, her wrists being held firmly by a panicked looking Tom while she struggled and fought against him. She was drenched in sweat, her eyes darting around in their sockets.

"Sam what happened? What did you see?" Tom asked when she had stopped struggling.

"I saw me and Mark running… we were… I think we… I think we blew up the hospital!"
