Here’s what he said about Sarah’s love triangle (spoilers):
THR: Sarah has to pick between Mark and Hank. The promo teased Hank moving to Minnesota to be closer to his ex-wife and daughter, should we take that as a sign that things look good for Mark?
Katims: She’s a lucky girl! That’s a high-class problem to have! You could take that as a sign. What we were hoping to do in this story was, when I look back when we started the season in the writers room, we wanted to try to create a true dilemma for Sarah, and we felt like there were things that would recommend both of these people to her and it would be a tough choice. It does get to the point where she has to pull the trigger one way or the other, and that’s what she does in the final episode. You can see she knows she has to make a decision and go one way or the other, but you also see that it’s not an easy decision to make. There are things drawing her toward both of these guys. It does come down to the wire, and she does make a choice.
THR: Is there a chance that one or both Ray Romano and Jason Ritter could return next season?
Katims: It’s always a combination of actors’ availability and their interest in doing it and a combination of that and the writers trying to figure out what the best story is for the characters. Both Jason and Ray have done such tremendous jobs in their roles on the show; they feel like part of the show; they don’t feel like guest stars.
