Billy had come in to decorate Teddy's locker for him, a surprise for when he got back, and something that kept him from worrying for a little while. He sat on the stairs outside HQ now, lost in thought, foot tapping anxiously, and the good feeling he'd gotten from leaving the surprise had long since worn of.
