A belated episode is pretty much all about offence. For once not our being offensive, but rather discussing when we're offended. This begins with a grilling of John for his new-found puritanical ways, and a grilling of Nick as to why he's so debauched.
There's unanimous celebration of the snow, as Nick revels in his joy about the weather. We walk dangerously close to the topic of gender once more, condemn those who've made their mind up about all manner of complex matters, then Nick describes the birth of a new racial stereotype. And we make it clear that Miranda is not funny.
