Owen and the crew race to a brawl at a male strip club, a fire at a bull semen factory and a protest where male toxicity is taken to a new level. Meanwhile, Paul tentatively goes out on a first date, Grace tries to reconnect with Judd and Owen faces the consequences of his chemo.
TK reveals it had been 116 days since his breakup with Alex, indicating three months have passed since he and Owen moved to Texas.
Brian Michael Smith had a hand in helping write his character, Paul's side story in the episode. With the bull factory emergency being one of his favorite incidents. 
The bull factory incident was inspired by a similar incident that took place in September 2019 in Victoria, Australia when a “genetics laboratory and storage facility” containing cattle semen caught fire, resulting in the cryogenic cylinders popping off projecting out of the building, similar to what happens in the episode.
A promotional image featuring TK and Carlos having dinner together was a cut scene, according to Tim Minear, due to their dialogue relating to the plot which had changed by the time filming for the episode finished up. 
Colleen asks Grace if it has really been 4 months since she was intimate with Judd when she says they haven't been together since the incident. This would have actually been 9 months prior.
