I saw this lovely comic by Max, and I thought I should add a little something of my own.

They get gold rings, eventually.

 The Things We Left Behind

Sam knows Dean from miles, and he can sense this isn’t a real laughter, he can feel the fakeness, he knows Dean is trying to cover up. 

But he doesn’t know how to help, he has no idea how to get rid of the mark, so he tries to help Dean by making him feel good, by laughing with him. 

He knows it won’t last long. But he will try and let Dean feel good as much as he can.
