Almost an hour after Sam and Dean had joined the two angels in their mock fight, Bobby called a stop to their games. Shoving a beer into the Winchesters hands, and some water into the angels, declaring that he wasn't going to waste good beer if it wasn't going to affect the two angels.
They spent the rest of the night in the lounge. Drinking and listening to the two angels talk about their childhood. All three men watched as Castiel and Gabriel sat next to each other, their wings left out to drape on the floor. Every now and then, the wings would brush, as if reaching out for comfort.
When Sam and Dean awoke the next morning the two angels were gone, but each had left a small feather for Bobby, as a thank you. Both Winchesters knew that it was unlikely that Castiel and Gabriel would be able to relax like they had the night before for a long time.
The knowledge that they had had that time, though was something that all three men thanked God for. Not something any of them did often.
