Season 4 picks up there with a vindictive war being waged between Deborah and Ava at the exact same time the network wants to externally highlight the female-focused camaraderie between the pair. Sharp-tongued insults rain down—not to mention line-crossing pranks (like when Deborah leaves a pair of Ava’s underwear in one of her colleague’s drawer). Let’s just say HR—and Winnie—are forced to get involved.

But that’s just it: Even though time has passed since season 3 ended, I’m still feeling warm and fuzzy over the mother/daughter-like relationship that deepened last season as they sought out the Late Night gig. Season 4 delivers a total 180 with the duo so hostile toward each other that it feels as though there’s no way to recover—at least not in 10 episodes (the length of this season). Simultaneously, viewers have been gifted a sense of renewed investment. Everything is the same, but also nothing and Deborah and Ava are power tripping their way through their new and high-stakes gig in a way that’s equal parts hilarious and hard to watch. (The humor is somehow supercharged by the conflict, too.)
