out-in-the-open:

So many brother feelings over this scene. The way Sammy just grabs on to Dean’s jacket and clutches it. The way Dean tries to talk Sam out of the dark thoughts. The way Sam tries to get his brother to safety. The way Dean refuses to leave Sam. The way Dean just inhales the smoke. 
It really is “there ain’t no me, if there ain’t no you” and it’s tragically beautiful.
