"Let me do it." Bobby's voice shakes.

Dean doesn't replay, he just watches his brother.

He's suffering.

Dean moves towards the bench.

The wall is down.

"Sorry, Sammy." Dean trembles.

"If you can't save him..."

Sam doesn't move anymore... he just sweats, tears running down his face.

"...you might have to kill him."

I tried so hard to save you.

Dean smiles gently, brushing the sweaty bangs out of Sam's eyes.

"Say 'hi' to mom and dad..." Dean bends down to touch Sam's forehead with his own. "Sammy, I lov-... see ya soon... hopefully."

Standing up, Dean lifts the gun.
