Choose me... Sam thinks, every time Dean runs off with some no name girl. He doesn't say it out loud. He never could, for fear that Dean would hate him. All Sam wants is his brother, and it makes him sick, but he needs it.
Every time Dean goes out with another girl, Sam's heart breaks a little more. It was only a matter of time before his heart shattered completely. The night Dean found him sobbing in their motel room, the night Sammy finally got what he wanted.
