Are there any fics where Uriel tries to make good on his oath (from the Halloween epi) and tries to eradicate Sammy, whether it's from Sam using his powers at a later point or Uriel just being...himself (i.e: kind of douchey)?
Bonus points if Cas and/or Dean interrupt but Sam's still screwed-up by it, so Dean gets Season One-esque protective of him.
