"Yes, Dean, it's me."
"I never got to say goodbye."
"Not forever, Dean. Just for the moment."
"Come back to me, please…"
"I want to, Dean, but I can't. …Not yet."
"Because it is not up to me."
"Cas, please, I'm begging you here."
"I want to, Dean. I do. But I can't."
"…This isn't fair."
"Dean, please don't cry…"
"I mean, why you, huh? Why this? Wh-… I can't do this anymore, Cas."
"No, whatever this is, a dream, a hallucination, I don't care. It's not fair. You didn't do anything wrong and you get royally boned."
"Please, Dean, don't get angry."
"Why the hell not, huh? First they treat you like a dog, then you fight, then you save everyone, and what do you get in return; you friggin explode. So I'm sorry if I'm not the poster child of peace right now."
"It's true, that did happen. But there is a plan for everything. And I will come back, Dean. I will come back… to you."
"…Cas… I can't do this. It's too much. It's… too big… I c-can't…"
"Dean, you have to. Please, Dean. You have to."
"Because, this is not the Dean I know. This is not the man I fell in love with. You have never given up, Dean. even in the most perilous times. You've always found a way. And you have to do that now."
"No. No excuses. You must do this Dean. Carry on until I come back. Please."
"…Okay, Cas… I guess…"
"Dean, promise me you will."
"Thank you, Dean. …I have to go now."
"Cas, no. Don't… Don't go."
"I have to Dean. I can't stay long."
"…Come back soon?"
"Of course Dean. I'm always with you, even if you can't see me."
"H-How do you know I can do this?"
"Because, I've seen you overcome much more when hope was thinner than a stand of hair."
"…How can you have so much faith in me?"
"Because, Dean, you had faith in me when no one else did."
"I've waited to see you for a thousand years, and I'll never leave you, Dean. But you mustn't let fear stand in front of you."
"I love you."
"…I love you too, Cas."
