Chrisha and Catherine discuss "Gimme Shelter"'s shipping elements, focusing in on Dean and Cas' parenting, that photo Cas used to summon the crossroads demon, and the problematic nature of Amara and Dean's past "relationship." They go on to muse about the series finale and what the effects may be for viewers past and present should the ship go/not go canon in a big way.
