Dean and Cas *are* acting married
But really.. Think about it. How long has it been since we’ve seen Dean flirt with anyone? Beth was totally his type, reminded me a lot of Lisa- petite, dark-haired, olive skinned, curvy. He didn’t even look at her properly.
And even afterwards, I assume Beth gave him her number because she thought he was hitting on her by coming by so late. And he ran with it because saying ‘Yeah lady, sorry wanted to murder you instead’ was obviously off the menu.
All I’m saying is Dean’s acting like a pretty committed man to me. Talking to the husband in between, updating him, ignoring all possible chances to have some no strings sex.
I think finding out Cas was possessed by Lucifer was a real wake up call for him. He’s been actually making amends with Cas- apologizing to him, trusting Cas, supporting him, talking to him frequently, making breakfast for him, offering to go with him. And I think it’s beautiful to see how focused he is on Cas.
