Leah Remini was a fun addition, but as I've mentioned before, she's really pulling the female character focus away from Holly (who was sidelined with the B-plot this episode) and Eden (who was all but absent this time). Now that she's getting back on her feet, you'd think she'd be around less... except the writers have her working in the frequented favorite watering hole of the main cast, so she'll have to keep popping up. With the season finale next week, something big could happen, but I'd go ahead and plan on having Nicki around next season, about which I (and obviously many others) have mixed feelings.
Phil finds out that he may have impregnated a woman, and decides that a vasectomy may be for him. Haskell thinks it'll help him sleep around more, so they decide to do it together. [I feel like this story has been done before, too, I just can't place it...] Holly makes it her mission to convince the guys that they might eventually want children, but it turns out that neither really goes through with it anyway. [that was a random Sonic product placement!]
