Cas and Sam made Dean and Gabe stay the night with them, deeming them both too unstable to drive home.

Gabe and Dean were sitting on the bed, sniffling every so often.

Dean looked down at Gabe. "Gabe, promise me something."

"W-What is it, Dean?"

"Promise me you won't give up. We'll both get married. Adopt a child, and we'll live the rest of our lives."

"Dean, I... I'm not gonna live as long as you..."

"Don't say that... Don't you dare say that. You don't know how long you're gonna live, Gabe. You might be cured."

"Dean..."

"Gabe, please don't give up..."

"I... Okay... I won't give up."

"Good... I love you."

"I love you too."
