SPOILER ALERT: The story includes details about Episode 5 of HBO Max‘s Stuart Fails To Save the Universe.

In Episode 5 of Big Bang Theory spinoff Stuart Fails To Save the Universe, our quartet of inter-dimensional travelers Stuart Bloom (Kevin Sussman), Denise (Lauren Lapkus), Bert (Brian Posehn) and Barry Kripke (John Ross Bowie), land in a tropical paradise inhabited by a primitive tribe of scantly-clothed beautiful people living in a commune where they share everything — food, shelter, and sexual partners.

All goes well until Kripke introduces the concept of possession and free market, leading to tribe members, who had been living in harmony, turning on each other and getting into fights, with him feigning innocence that he has no idea how the turmoil started.

It’s probably fitting that it was Kripke who destroyed utopia.

However, “Chuck brought up a point earlier today, saying that Bert has a little hand in that by bringing monogamy into their world, like maybe he should have never done that,” Posehn said in an interview with Deadline, referencing Chuck Lorre, co-creator of Stuart Fails To Save the Universe alongside Bill Prady and Zak Penn.

Added Bowie, “Yeah, it’s funny because we have been collectively all blaming Kripke for introducing the free market to paradise, but yeah, Burt holds some responsibility for introducing monogamy as well.”

In the episode, Bert is immediately propositioned by one of the gorgeous local women, who quickly becomes his girlfriend, stopping to sleep with others upon Bert’s request as they are headed to the altar.

“It felt that episode was incredibly fun to shoot because we like joke-wise, it’s just one killer joke after another in that show,” Bowie said. “But also, it made kind of perfect sense that Kripke would be a big part of bringing down Utopia. And then the way that he completely shirked responsibility at the end — that sense of like, wow, what got into these guys? That was really great. And that cast, oh my God! They found all these beautiful people who were all really funny, all these like gorgeous people who would come in and land jokes, and it was incredible to watch.”

Five episodes in, Bert has had the coolest arc of the main characters — from turning commando in Episode 1 to bring mayhem to Caltech and then kicking Kripke’s butt after he’d killed Raj, to doing magic and having a posse of adoring acolytes in Episode 3 to landing a stunning girlfriend in Episode 5.

Posehn is loving it.

“Well, just getting Bert to do more was already a dream,” he said. “But then the stuff they put me through in the first season was so fun. Every week there was something new, some new thing that I went home to my wife and said, ‘Holy shi*, you won’t believe what Bert’s doing this week.’”

Added Bowie, “Well, you were both a fighter and a lover, and that was fun to watch.”

Stuart Fails To Save The Universe has been renewed for a second season.
