Hee! Dean's going to have the absolute best time in Atlantis. I mean, that's got to be one of the best vacations ever, at least for him: Danger! Blowing shit up! Monsters to shoot! Beautiful women hoping for a slice of the pretty!

A far better disappearing act than the one he pulled in canon with his whole hell adventure, though I bet Sam is really going off the deep-end.... I'm guessing this story will eventually head back that way, if not in this one.

Someway to sneak Castiel into the mix in the future, y/y? He's all that's missing.

Though I could be perfectly happy imagining Dean sticking with the SGC/Atlantis forever and ever.
