Set in S4 EP: 7 - (May not be 100% Canon)

It was a bit of an aback when Dean and Sam meet Uriel.. He was an asshole. Not in a rude way, just.. As any angel that they meet. It was a dangerous case this time: a witch wanted to summon the creature of Halloween, and the reason of Halloween to exist.. Which was to protect themselves from such a creature dressing up as monsters and giving sacrifices in case that it didn't work.

Uriel and Dean hated eachother.. And that was as clear as the water. They were discussing about if erasing the town or not, but it was not debateable.. Divine orders said to erase it, but Dean and Sam didn't wanted to, so after quite the long discussion, Uriel was going to beat Dean up as he approached with hostility and the fists clenched.

-- ' You wasted my patience- '

Uriel said as he approached Dean. Castiel wasn't going to let him do that. Uriel knew from first hand that Castiel had a liking for Dean, and for Uriel it was clear.
