[@ActRaiserTheReturned] I only wouldn't suggest he get into a fight with an angel.  If you're wanting to get him into a fight, you could write his own NPCs until they finish up with all the angel drama of this little part.

Dean's going to meet Castiel, which is kinda a set in stone thing.
Samael is gonna get poofed back to heaven, which leaves him kinda out of it. lol

This is one of the few times I don't have a direct answer for what you should do, but I do want you active again.
