Angelic marriage rites were never intended to go quite like this.
When are wedding/bonding fics not fun? The answer is they're always fun. I really enjoyed Dean's voice in this, I mean it is essentially a Dean that is happy which is not exactly in-character but his character in this fic was still great and engaging. Cas was great too but clearly I was pretty drawn to Dean in this. I'm more of a fun and engaging then angstful and depressing kind of fic gal. And this fitted the brief pretty well.
"What the hell?" Dean had said, and, "Where have you been?" and, like Cas was the boy blocking his calls and Dean was three steps away from turning stalker, God help him, "Why didn't you answer me the first three times?"
"I was busy," Castiel said.
And really, Dean should have asked this first, but, "Why are you naked?"
