I'm looking for a story where Castiel finds Dean on or near his Impala sulking, and the angel finds out it's because the Campbells (specifically Christian and Gwen I think), were belittling and putting Dean down at every chance they could. Castiel then realizes that the Campbells are trying to summon him to trap him, but it doesn't work. Castiel confronts them on his own and flings and pins Christian and Gwen to the walls and threatens them for what they did to Dean, which resulted in Christian getting his eyes burned out.
