Trust is a two way street and Cas didn’t trust him and so now he’s pissed. no. not pissed. Hurt. Why did that hurt so damn much?
It only works if he means it. What if he doesn’t mean it right now?
Or what is he doesn’t forgive Dean for the way he talked to him?
"Yeah, you always do.” “Yeah, well, you know, even banged up, Sammy comes through.” “We don't need your help.”
"Cas, are you there? Sammy's hurt. He's hurt, uh – he's hurt pretty bad. And, um... I know you think that I'm pissed at you, okay? But I don't care that the angels fell. So whatever you did or didn't do, it doesn't matter, okay? We'll work it out. Please, man, I need you here... Screw it. Okay, listen up. This one goes out to any angel with their ears on. This is Dean Winchester... And I need your help.” (x)
