SCDP part of the firm post merger was getting marginalized. Don was ousted, Roger is getting hammered, Peggy being sidelined by both Lou and the Jewish creative, Campbell was exiled at LA getting no credit for his accounts. Only Ken survived with his father in law relationship.
Little finger lost his swag this episode. He used to be portrayed as a sleek talker, somewhat charismatic, romantic, and makes no enemies. but in this episode he's pretty darn evil and even Sansa look at him differently.
