Re: the dinner. Deb was at her shrink talking about the dinner from the night before….wearing the same clothing. I don't think her and Matthews got down and dirty, I think the writers made a continuity error. 
THIS SHOW!

My husband and I paused the show to suss out that very topic.

I found myself cringing at the Deb/Dexter scenes, knowing the shit storm going on behind the scenes there. How awkward that must be - to work with your ex-husband, whom you met on the show, after he cheated with last season's love interest.

I spent almost the entire second half of the episode trying to figure out who Frank looked like then it hit me: Oswald Chesterfield Cobblepot.
