Dean lets out the biggest sigh of relief when he sees Sam. He was so worried that he wouldn't be able to find him (or worse find him dead) but there he is, standing as freakishly tall as ever, right as rain, and Dean feels half the poison clenching in his gut just slip away. At least whatever's going on, they're in it together and they're always better at finding a way out when that's the case.

"Sammy! Thank god!" He's so relieved that he starts jogging towards him without even a thought spared to the fact that he still has that massive, rusty blade in his hands and raised high.
