William Birkin had not been interested in coming. When he'd received the invitation to the "opening ceremonies", as Spencer had called them, he'd scoffed and decided they were of little use to him. He'd never been good with people, and he didn't really care what Spencer had to say.
Spencer must have realized what William's reaction would be -- because at the end of his call, he'd told William that Albert Wesker would be there.
William couldn't ignore the (perhaps irrational) animosity that he felt towards Wesker at this time. The realization when he'd been speaking with Sergei that it was common knowledge that William had been "hibernating" care of Umbrella... and Albert, his closest (his only) friend, had never come to free him? To even see him?
It left a bitter taste in William's mouth -- but the need for closure had arisen, and, he supposed, Spencer wasn't really giving him a choice anyway.
He'd shaved and showered (and although it got rid of the facial hair he'd been growing quite well while he'd been out, it hadn't done anything to get rid of the massive scarring that had occurred down his right arm) and made his way to the abandoned hotel and "convention center".
When he walked in the door of the designated room, he lingered a moment, his eyes scanning the occupants. He... recognized them. S.T.A.R.S. members. William's lips pursed, and, deciding he had nothing to say, moved into the corner nearest the doors, arms crossed, keeping his eyes hard on all of them.
