I love that when Cas stopped Dean from becoming Michael’s vessel Dean just decided to resort to homoerotic flirtatious insults because it’s so???
He’s just all like “Blow me Cas!!!” and “Last time someone looked at me like that, I got laid 😉” like???? What exactly did he think he was doing??? What was going through his mind???
He really went “Wow you won’t let me sacrifice myself??? Well why don’t you just fuck me then, huh??? Why don’t we suck each other’s dicks right now??? We should have crazy angry sex right this second. Let’s do it. I bet you won’t.”
