Catherine isn't the only female who feels the consequences of being a woman in the Cody family. It's explained in the show that before the events of the series, J's mom, Julia, who is also Pope's twin sister, had a difficult relationship with Smurf.
Like Catherine, Julia was able to rein in Pope in a way that Smurf was used to doing herself.
Smurf saw Julia as a threat as much as she saw Catherine as one. And, Shawn Hatosy, who plays Pope, told Distractify in a September 2021 interview that Season 6 will dive into that dynamic through flashbacks.
"As the story goes on and we finish up Season 5 and start to head into Season 6, you get to see what the fracture between Smurf and Julia was exactly, and how that sort of pushes and pulls at Pope ... and his decision to align with Smurf," Shawn said.
