Bill had woken up about ten minutes ago, close to tears. He lay in bed for a minute or so, trying to work out why he felt so completely and utterly devastated when he had no reason to, and then he realized what was going on and who was feeling like that. "Richie," he breathed out, and was out of bed and pulling on a t-shirt within seconds.
He knew not to bother checking his friend's room, and headed straight for the elevator. Now would have been a damn good time for him to suddenly learn teleportation without needing someone else to be in the right place, but that didn't happen. He had to use the high-speed elevators and run in-between times instead.
He didn't burst in through the doors to Bad Things, though. He slipped in quietly and headed straight for his best friend, then wrapped his arms around him and just held Richie as he cried.
