"I'm not going through this again Cas." Dean said holding the gun to his head. "I can't lose Sammy again. First time a sold my soul to the demon, second time you dragged him out. This time, I can't. You can't. Every time we try to save each others bloody asses, one of us gets pulled back down there. I'm not going to put up with it again."
Castiel pleaded, he was on his knees. It couldn't happen this way, he'd always thought the Winchesters would die happy. Not like this. Sam had been dragged back down to hell and Dean was about to pull the trigger.
"Dean, I know you're upset. But we can still save him, there's still time!"
"Damn it Cas!" Dean yelled. "We can't keep doing this. No matter what it'll always end the same way. The least I could do is trade with Sam, but what good will that do?"
"Dean, I can pull him up again. Like last time. Like with you!"
"No Cas, you can't. It'll be me next time. And then Sammy again, And then me again, and it'll go on like that until we're all dead. You can save him Cas, get him out… send him to heaven. Just let me go there to, I'll meet you there."
"NO!" Castiel shouted, he jumped and grabbed the gun out of Dean's hand and held him to the floor. "You're not going to do this. You know why?"
"Because we'll save him?"
"Because we'll save him, we'll save you. We'll save the whole damn world. You just need to hold on for a little longer."
"Why?" Dean asked, losing his patience. He just wanted out.
"I need you to help me."
"No, no you don't."
"Yes I do. Because you know what?"
"What?"
"I love you Dean Winchester."
This caught Dean off guard, enough so that Cas could steal his gun and hold Dean still. As Dean stayed silent, Cas carried on talking, "Angels aren't allowed to have emotions, but I can't hide it anymore. Now we are going to save your brother, and I am going to make sure no one can ever harm you two again. Because without you around me, I am incomplete. And without Sam…" Cas sighed. "Well, it feels like I've lost my family. We will save him Dean, we will."
Dean stared into the angel's eyes, knowing he was telling the truth. He would save his brother, and nothing was going to them ever again. And he knew… He loved this man with everything.
He pulled him closer, and brought the angels mouth to his own. And just before kissing him he said: "I love you too, dumbass." And he kissed him. Sammy was going to be saved, but right now… this was what he had been waiting for, for five years.
