Hey, kids! You know what's cool? Adultery! Without the series outwardly announcing it, we glean that Tori and Trina's mom is having an affair with their dad's police partner Gary. Throughout the last season, we hear their mom waxing poetic about Gary. The biggest revelations on this front comes from the Season 3 episode "Crazy Ponnie" when Tori's dad is out of town and she's being stalked by a former Hollywood Arts student.
When Tori pleads with her mom that she just wants someone to listen to her about her stalker, it's heavily implied that her mom is texting Gary rather than paying attention to her terrified daughter. When Tori's mom brings up enlisting Gary for help, her mom openly says, "I know, he's handsome, right?" That's a pretty uncomfortable thing to say to your daughter's face.
Once Gary apprehends Tori's stalker, he says with a smirk, "Just tell your mom I send her my best." Tori is not amused, and neither is the audience. It's almost certain that they're having an affair, a suggestion that's played out for laughs ... on a kid's show. It's not like children or teens are unaware that cheating exists, but the episode chooses to glorify it. This adds salt to the wound of all the critical "adult" topics the show fails to explore, like LGBTQ+ characters and mental health treatment. But sure, it'll grant screen time to adultery.
