Bobby whines. Crowley returns, it seems he planted a tracking device in the brothers car that has not been noticed until now. He offers to help the brothers’ track down Sneezey aka Pestilence. This is done via the Horsemen’s boot boy Brady who just happens to be Sam’s BFF from Stanford.
It seems Brady set up Sam’s relationship with Jess and killed her. Sam meanwhile comes up with a plan to stop Lucifer and it’s one of his stupid, arrogant plans which shows that he never learns.
Invisible hellhounds fight. Crowley makes Bobby an offer. Sam kills Brady and exorcising him isn’t even mentioned. This was okayish.
