Chris Geere and Desmin Borges talk about the new season of FXX's "You're the Worst," which premieres 10 p.m. Sept. 6.

LOS ANGELES -- FXX’s “You’re the Worst" returns for season four Sept. 6 to finally answer that age-old question: can someone be forgiven for proposing to you and then immediately abandoning you on a hilltop?

When last we saw the raunchy but insightful comedy’s dynamic and dysfunctional duo, Jimmy (Chris Geere) and Gretchen (Aya Cash), he was fleeing the scene of his elaborate proposal -- to which she said yes. Naturally, the new season finds the pair testing out the theory that absence makes the heart grow fonder.

“It’s a season of separation in many ways for these two,” said Geere, over the phone during a break from shooting the season finale in Los Angeles.

The separation won’t be easy for fans of the cynical, but warm relationship. Geere said he has only shot four days with Cash all season, prior to the season finale.

But don’t worry, Worsties. He promised the show is still the “convoluted” love story it’s always been, and the core foursome will reunite in a fantastic way as the season winds down. But first, they have to deal with the emotional fallout of Jimmy’s decision realistically.

“This season, in short, is about Jimmy and Gretchen navigating their way back to each other,” he said. “Them trying to figure out how they can be happy, but never be hurt again.”

As for Jimmy, he’s taken to his normal strategy for dealing with big emotional moments -- avoiding them altogether. In the season premiere, he’s living in a remote mountainside retirement trailer park community, avoiding any contact with his friends and working as a YouTube-trained carpenter.

“The fact that he has gone somewhere so remote and quiet is simply highlighting that he is not going to take any responsibility for what happened in the season finale,” Geere said.

While no actor wants their character to be hated by fans, Geere said he thinks Jimmy deserves some of the audience’s ire this season.

“I finally appreciated this year that I think it is important that they do hate Jimmy for a little bit and aren’t on board with him because he behaved (badly),” he said.

Back in LA, Gretchen is avoiding her own grieving process by holing up in the tiny apartment now owned by Lindsey (Kether Donohue), who’s actually found a stable, fulfilling job in fashion after her divorce.

At Jimmy and Gretchen’s house, newly single Edgar (Desmin Borges) is also thriving with a new comedy writing gig after a season that saw him crawl his way back from a heartbreaking PTSD spiral.

But Borges said, after that fall, Edgar has found his groove.

“We are finding probably the coolest, smoothest Edgar that we’ve ever seen, which has been fun to play,” he said.

But on a show that has never shied away from poking its characters’ worst impulses or prodding their deepest problems, don’t expect Edgar to just suddenly be OK.

With some money in his bank account and a freedom from underneath Jimmy’s shadow, Borges said Edgar will find himself in new territory.

“Biggie Smalls said it best: ‘Mo money, mo problems,’” he said. “Edgar has always been monetarily cautious. Once things start happening, he gets a little looser with his cash flow and finds himself in situations he normally wouldn’t be in, and he begins to spiral again.”

Having built a friendship on lording his superiority over Edgar, Jimmy won’t be too keen on this new self-assured Edgar when he resurfaces, Borges said. Edgar, normally one to secede power to his roommate, won’t easily back down either.

“There is a lot of love between Jimmy and Edgar,” Borges said. “There has to be in order for them to stay in the relationship and situation they have made. But the role reversal is interesting. Jimmy does not like it and Edgar isn’t losing his ground this time.”

Four seasons into anti-romantic comedy, Geere said the cast, creator Stephen Falk and the writers have found a rhythm with one another.

He and Borges both said they love digging into the Jimmy/Edgar friendship, and Borges said Donohue is the "most fearless" actor with whom he's ever worked.

But most importantly, there’s an understanding among the actors their cruel-but-lovable characters must share the load of being the worst.

“I think it’s important that none of us go into a scene with the aim of wanting to be liked,” he said. “They are still messed up, they’re broken people.”

Luckily for the foursome, Geere said there’s always someone worse out there.

“I think that will always be Becca,” he said, of Janey Varney’s supporting character.

"You're the Worst" returns 10 p.m. Sept. 6 with a one-hour season premiere on FXX.
