2. don't it make your black eyes white
Every time Sam's muscles jerk and convulse, Dean curses Ruby's name.
Kid's going through withdrawal. It's hard and it's messy. They hole up in a cabin out in the woods. Any mojo Sam has starts to fade, but not soon enough. He's dangerous in his delirium.
"Pl-please, Dean, I- I need it…"
"I know you do, Sammy. But it's not gonna happen."
Sam's eyes glow as he lashes out. Dean's healed himself three times so far. No big deal.
Ruby as Lillith showed the whites of her eyes as she died, and she died very slowly.
Dean saw to that.
Two down. Four to go.
