Richie had had the wherewithal once he'd woke up from all that Death Snooze to take a (very long, quite possibly very traumatized) shower and change into clothes that weren't dirty and blood stained. He'd probably burn the old ones later, there was going to be no fixing that mess.
He didn't bother with shoes. Eddie was really only a few doors down and he didn't expect to be out in the hall long -- and was right in thinking so. When he pushed the door open and spotted Eddie on the bed, it was with damp hair and a slightly haunted expression. The expression, he tried swiping left on because there was no point in making a big deal out of something that was over and done with, he figured. His hair, he couldn't do much about.
The booze was spotted, the small bit of mess of the room was noted and Richie could have wept for how cute Eddie looked on the bed, how perfectly Eddie. "Hey Big Bill," he said to the hamster across the room, but closed the door behind himself and moved to flop onto the bed, crawling up in order to crowd into Eddie's space.
