Best Winchester Brotherly Bonding Scenes 

I love this scene. It’s so clear from their expressions that they are remembering all the times they spent in the back seat together. Dean making sure Sammy is comfortable. Sam laying his head on Dean’s lap or shoulder going to sleep. I think it is also a reminder that they always had each other. And despite everything, things were alright as long as they were together, looking after each other.
