Hot Messenger is just Hot Mess Angel Spelled Wrong

When Ratatoskr, who more commonly goes by Dean these days, get a distress call about an angel nearly knocking down the doors of Valhalla he has to be the one to look into it. Turns out Castiel is an angel with a new job as messenger but he has no idea what he's doing. Dean is willing to show him the ropes, but mostly because the angel is just as cute as he is weird.
