My favorite destiel trope is when Dean laughs at all of Cas's jokes, and thinks he is SO funny, but literally nobody else even realizes that Cas is telling a joke. It butters my biscuit.
perhaps my most realistic take perhaps my most delusional one but i think no destiel in the revival would be too hard to sell to anyone at this point and none of the actors would look forward to having to explain that to the fans, therefore destiel will happen
