Checking in with AYA CASH

Can the ever-shaky relationship of the central characters on “You’re the Worst” get even worse? Oh, yes.

Sufficient evidence is supplied by the ever-edgy FXX comedy’s fourth-season premiere Wednesday, Sept. 6, an hour-long tale that shows how Gretchen and Jimmy (played by Aya Cash and Chris Geere) are dealing – or not – with their breakup. The AWOL Jimmy finds refuge in trying to help some colorful senior citizens, while Gretchen drives her best friend Lindsay (Kether Donohue) not-so-mildly crazy by becoming a constant, high-strung presence ... even at Lindsay’s business meetings.

“Kether kept saying, ‘I’m so boring in this scene,’ and I kept saying, ‘I’m so overacting,’ ” Cash laughs of their work together in the Season 4 debut. The arguable high point is Cash emulating the ultra-speedy recitation of the lyrics of a certain song: “I did not know ‘One Week’ by Barenaked Ladies. And if you did, I’m so sorry. It’s still a recurring nightmare for me.”

As dryly humorous as her “You’re the Worst” alter ego is, Cash looks back fondly on her earlier television work on such shows as “The Newsroom,” recognizing that her current role associates her more closely with a certain type of character. Still, she appreciates the challenges and the freedom “You’re the Worst” creator and executive producer Stephen Falk continues to provide her.

During the second season, the revelation of Gretchen’s clinical depression became a muchdiscussed aspect. Reasoning that “obviously, that’s not something that goes away,” Cash notes that “you can see the ripples of that in almost everything. I think this season, you’ll see Gretchen in more of a manic state than a depressive state in response to the break-up. We’re not talking about it in the way that we did in Season 2, but hopefully, you’ll see it reverberate.” Birthdate: July 13, 1982 Birthplace: San Francisco Current residence: New York Marital status: Married to actor-producer Josh Alexander
