in my feminism class my professor always gives us a question and we all answer it and todays was “whats your most treasured memory” and since i just spent the weekend with The Gf i was like “i just saw my long distance gf for the first time and it was amazing. and disclaimer i didnt finish my essay because i was too gay” and then everyone laughed and i guess i forgot that ppl don’t just say that they’re too gay irl and my professor was like “did you just say you were too gay” i was like yeah and she thought that was a valid excuse for not doing my essay so. art school is great sometimes
Dean has been trying to be open with Cas, telling him he's worried, we're better together and Cas doesn't really respond except with what could be called flippancy saying I didn't mean to add to your burden or betrays him again. So it's not that Dean needs to open his mouth, it's that when he does, he's shut down. This happens a lot in the series with other people too and I think we undervalue how much that shapes Dean's willingness to open up. As in, I think we often ignore it completely.
