Sylar

Angela stepped out of the alcove across the hall like a ghost and raised the gun she carried, training it on Gabriella's back almost casually. She allowed herself a moment's hope that the girl wouldn't scream -- she didn't want Sylar barging in on them right away -- and then pulled the trigger, the silencer she'd screwed onto the muzzle hours ago serving to mute the better part of the sound of fire.
