The elevator ding brought McGee out of his revelry. Abby had certainly done everything she could to prompt some memories. Or perhaps create some new ones. The little room in the lab had been festooned with scented candles with labels like 'to enhance memory', and 'to encourage familiarity'. It all looked a little crazy, especially when she brought out the handcuffs. But then she had taken off her top and he'd seen the giant tattoo on her back. Strangely, he thought the little tattoo on his butt made him like the key and her, the lock. The analogy worked well on many levels, given what they had just done.

Ducky was right, he was feeling like a nap, but it might not be due to the bump on the head.

He made his way from the elevator to the bullpen, searching the faces around him for any signs of familiarity. He might as well be walking in a chicken yard. They all looked alike.

"We've you been?" asked Gibbs gruffly.

"Ahh, Abby was trying to prompt some memories", he said walking over to where Ziva was rhythmically bashing her head on her monitor. Did he just imagine Tony reaching for his wallet again? Ah well, even if it was a bet, he probably did better out of it than Tony.

Ziva automatically gave him space as he neared her keyboard. He took one look at the screen, frowned, did a cntrl-alt-del to kill of the offending program and then headed off to his own desk.

"Did Abby's little session work?" asked Gibbs watching him move from Ziva's desk.

Tony looked up with great interest on his face.

"Ahh, sort of..", he wasn't sure how to phrase this, "I sort of got some vision of a coffin, which Abby said was a good sign."

Gibbs eyebrows shot up, "What were you doing? You know she sleeps in a coffin", then he paused, "Not just sleeps."

McGee averted his eyes. These people knew way too much about each other. "We were, well, it involved scented candles and handcuffs…"

"She's done that to you before", Tony chimed in.

"Really?"

He turned his attention to Gibbs. "I seem to remember all the work stuff, just not the social stuff," he said slowly, considering the facts. "Like I can read my own code but I can't work out what the deal is with Tony."

"It's like a big brother, little brother thing", Tony explained.

McGee turned to him: "So which of us is the older brother?"

Tony pulled a face at him.

"Actually, I've always seen you as good twin, evil twin", said Ziva wistfully.

McGee nodded his head thoughtfully, accepting this.

"Hey…", said Tony, "Aren't you going to ask who is who?"

"Nope", said McGee.

Tony could hold back no longer, "Thwack", he clipped McGee up the back of the head. It felt so good: a great release of pent up frustration.

"Hey……", McGee complained, "I hate it when you do that."

Tony, Gibbs and Ziva stared at him.

"You what?" Tony clarified.

McGee savoured the words slowly, "I hate it when you do that", he repeated. 'You do it a lot and it always feels the same. Just like that."

Slowly the light was dawning. The place felt familiar, the people looked familiar. The sea of anonymous faces was beginning to take on personalities: friend, enemy and complete stranger. He knew where he was and who he was.

He smiled. He also knew who that girl was on his ipod and why Tony was never going to find out who she was.

Tony was grinning at him, so was Ziva, even Gibbs seemed to have a shine in his eyes. It must have written all over his face. Tony came over and put an arm around him.

"Welcome back kid", he said affectionately.

Then he lowered his voice. "You might want to put the innocent expression back on, though; Abby's planning on a very adventurous night to jog your memory."

McGee's eyes opened wide in excitement and anticipation. "Abby who?" he said.
