Following a quick examination of her jaw, by which she determined it was just bruised, she locked her eyes with the scalpel he must have dropped on the floor after Mark's monologue. She made for it as quietly as she could, and quickly secured it in her grasp.

She then stood up and faced the man who still had his fingers wrapped tightly around Mark's neck and raised the blade.

"Get off him. Now." She called out sternly.

"'Ang on a min darlin' I'll deal with you soon" He muttered, waving a dismissing arm at her.

"I said get off him. Now." Sam repeated, raising her voice slightly.

He sighed and let go of Mark's neck, leaving him gasping for breath on the trolley. He turned and started muttering something about 'dealin' with you first' before freezing in his tracks as he caught site of the scalpel that Sam was pointing squarely at his chest.

"Now now darlin'" He said as though trying to tame a wild beast, "Let's not get ahead of ourselves 'ere…"

"I can think of six different places to stab you that aren't fatal but would definitely incapacitate you until the blade was removed. I can think of over a hundred more which would end in your death, and I can think of one place to kick you that would cause excruciating pain." Sam emphasised her last point by looking down briefly at the place she was referring to.

"Alrigh' then. Wadoya want me to do?" He asked, placing a hand between Sam and the implied region.

"I want you to walk over and unlock that door." Sam replied simply.

"I'm afraid I can't do that, darlin'," He replied with a cheesy grin. "Why don't you?"

"Because the second I turn away you're going to try and grab the knife from me, knock me out or continue to strangle Mark. Or all three. Now get over there." Sam replied more calmly that she felt.

"I'm not goin' ta do that." He replied, widening his smile.

"Fine. Then I guess I'll incapacitate you." Sam said with a cold stare.

She wanted desperately to look back at Tom and Zoe and apologize for what she was about to do, but at this late stage that would not make any difference. Her hands were beginning to shake at the thought of harming a person, which made her frown. She had killed a man before, so why was holding a scalpel and threatening to cut making her shake like a child?

After several moments her captive spoke.

"If you're gonna be incapacitatin' me can ya get on with it already?" He said with the barest hint of laughter.

"You're in a hurry to get injured." Sam replied, hoping he didn't notice the shake in his voice.

"Well, darlin', not I'm not actually and I'll tell ya why. You're hands 'n' voice are both shakin' like a cold 'n' wet dog meaning you don't have the balls to carry your threat through."

"Don't bet on it." Sam replied, this time with no shake in her voice.

"Oh I'll bet on it." He replied menacingly before lurching forwards and attempting the grab the knife.

Unfortunately for him when he lurched forwards he left a 'delicate area' unprotected, so though he appeared to make some headway by grabbing the knife and almost stabbing Sam in the neck, she easily dodged and a quick knee to his sensitive area sent him howling in pain to the ground, rolling around on the floor with the scalpel long forgotten.

"I did warn you." Was Sam's only reply before she stepped over the man howling in pain and unlocked the door.

Tom had insisted on getting Sam checked out, much to her annoyance, and so three hours later she was sitting in on a bed in AAU waiting for the results of her facial X-Ray to see if her jaw was broken while Tom fussed over every bump and bruise that had appeared on her skin.

"Tom for god's sake!" She shouted when she finally couldn't take a second more of the fussing.

"I'm just making sure you're ok!" He replied, unsure of what he had done wrong.

"Tom I've already been checked out!" Sam replied exasperatedly, "and by over four different doctors, all at your request. I am fine."

"Let's wait for the results of the X-ray to determine that." Tom replied simply.

Sam felt like howling just as her captor had.

She had been to check on Mark, whose fever had broken around an hour ago and was looking much better, and watched as his crazy boss was carted away in handcuffs with Tom and Zoe by her side. Now all she wanted to do was go home and sleep, wherever home was exactly for she had lost the address.

After another half an hour wait Zoe came clopping over with her X-Ray results.

"You're absolutely fine, Sam." She said cheerfully.

Tom, not trusing anyone's judgement but his own, grabbed the envelope she was holding and took out the X-ray, holding it up to the light.

"There's an old break here." He said with a frown.

"What?"Sam asked, standing up and looking at the X-ray herself.

"Here," Tom said, pointing at where it had healed over, "It looks to be a few years old at least. Any idea how you got it?"

"Not a clue." Sam replied with a frown, "Can we just get out of here already?"

"Yes that's fine." Zoe replied as Tom look for confirmation, "But to be on the safe side I think its best you stay with someone over the next few days. You did take quite a knock to the head."

Zoe looked disapprovingly at Tom.

"You can stay with me if you like." Tom replied hopefully.

"…fine." Sam replied, confused by his obvious excitement.

Ok so that's the end of the whodunit section, now onto the Sam gets her memory back/finds out what happened to her brother/falls in love with Tom part.
