Sam holds the gun with both hands, with Dad's hands holding him steady, and pulls the trigger; a beer bottle explodes. Dad lets go and Sam aims at the next bottle and misses by a mile. "Don't feel bad, Sammy," Dean says, "maybe you just gotta get bigger first," and Sam glares at Dean and thinks iyou can do this, I need to do this if I'm gonna be as good as you/i, and takes more careful aim, and puts a hole in the fence under the bottle; that's good, that means he's getting better.
