I think that Connor, Mandy's brother, has become the breakout character of Georgie & Mandy's First Marriage. That is due to how Connor had an impressive arc from just comedic relief to a character with emotional depth, and I think the scene where he tells Georgie about how he feels like a failure in relation to his father had some really powerful moments. I also like how Connor is effectively the character who least seeks out fighting somebody else, and in a show where conflicts are quite frequent, that is refreshing.
