(2 part anon) UGH why. Ok, let me see if i can remember everything from the first part. I think it was basically just that they focused a lot on Dean's reactions, and that while Sam was obviously very clearly upset, Dean was *devastated.* He doesn't run off with Sam to attend to more urgent and immediate matters. He can't. Those were basically the highlights of the first part i think, just pointing out the very obvious difference in their reactions and how it was clearly intentional.
2/2 In all honesty, this has got to be the most blatant “Dean’s bond with Cas is different” moment ever. It’s a standard tragic romantic trope. Sam’s not the one who fell on his knees next to Cas’s body. They chose Dean for that. I wonder why?:P And Dean didn’t even have to say anything, it was all body language and expressions. That’s not even subtext, it’s right there on the screen the two brothers different reactions to Cas.
HI! And thanks for sending part 1 again! Sorry it took so long for me to answer, but yeah, I absolutely agree with you. I’ve seen (reblogged? Probably?) several gif sets over the last few days comparing these things, and also comparing Dean falling to his knees with Cain falling to his knees at Colette’s grave in 9.11, as well as Sam pulling Dean through the portal the same way Dean pulled Sam out of his burning house where Jess had just died in 1.01.
So not only are we seeing Dean’s AND Sam’s reactions here as very different, we’re seeing Dean’s behavior basically identical to other explicitly romantic relationships on the show.
