Cas watched while Sam moved restlessly around the library of the Bunker. He opened a book, closed it, picked another book and set it back. He eyed Dean's computer like he'd rip it out of Dean's hands, but Dean only gave him a a fast, "Don't even think about it," and Sam went back to pacing the floor, thumbing the bookshelves, and grumbling to himself.
Finally, with a growl, he marched out of the room and soon they could hear the sound of gunfire from the shooting range.
"What's wrong with Sam?" Cas asked.
"His computer is in the shop…"
A/N: My computer is in the shop and I'm going crazy! (I slipped this in while the Boss was busy doing something else.)
