[ Sam can't help it, he laughs at his brother. For about 5 minutes he thought Dean was gone forever so his brother's usual wit is met with a jocularity that Sam probably shouldn't feel at the moment.

He snaps to attention, giving Dean a mock salute.]

Yes, Dean. Understood.

[ Sam was about to protest but the peacoat, which was totally Sam's style, was warm and smelled like his brother so he took comfort in that while he could. ]

Thanks. [Said softly and with a grateful smile as he let the coat take the chill off. ]

No... We left Chuck on the side of the road. You didn't kill him, Dean. He wanted you to but you... were awesome, man. I was so proud to be your brother. Jack took his power, so as far as I know, he's like us. Which is a good thing. Wait, Jack's not here, right?

[He reaches out to grab his brother's arm in momentary panic. ]
