Only after getting home, Sam realized that he didn't really want to be there. He figured that he could head back to Ruby's place and crash there again, but at this hour, Sam didn't want to bother her. Especially not if he was going to wander in to interrupt any forbidden love between her and Cas. God, how did that even work anyway? Weren't angels supposed to be made without those functioning parts required for sex in the first place?
Yeah. He definitely wasn't entirely sober. Otherwise thinking about anything below Castiel's waist would not have happened. Ever.
Shaking all disturbing thoughts about Castiel from his mind, Sam came to the conclusion that he would take what cash he had on him and put it toward a hotel room. There were a few decent places in this area. He had crashed in a few of them before Dean came around, back when he was constantly moving from place to place. All he had to do was grab some clothes and his toothbrush and he'd be set for when he woke up in the morning. Then he could attempt a subtle slip back into the house and go about his merry way like nothing was wrong. Again.
Having dug up what he needed from his room, sneaking around Heather while she was asleep, Sam started back out the house with his backpack in hand. It was only when he hit the doorway to the side entrance that he noticed the man who was waiting for him there. Blinking slightly, he eyed John warily for a moment, obviously not so certain as to what it was that he was looking at. Was he really sitting there? At this hour? Why would he - unless...
He pushed the door shut behind him and looked off at his father, brow furrowing. "You didn't have to wait up for me."
