On her thirteenth birthday, her big sister Bex (Lilan Bowden) announces that she is moving back home. AND that she's actually Andi's mother! The people Andi has been calling Mom and Dad, Celia (Lauren Tom) and Ham (Stoney Westmoreland), are actually her grandparents.
Most girls who have babies in high school depend on the grandparents for help with everything from childcare to finances, but pretending that the grandparents are the parents sounds like a very poor decision. But it makes for lots of interesting conflicts.
And they retaliate by calling up the father, rock star Bowie (Trent Garrett, above), who apparently was never told that his ex-girlfriend had a daughter. (Wait -- doesn't he have a legal right to visitation, and a legal obligation to provide child support?) He shows up, eager to start fathering Andi.
The fluid family dynamic, so different from the usual teencom Mom, Dad, and Kids, strikes me as a reflection of the various ways that queer people make their own families.
Other than her crazy family, Andi has two best friends, Cyrus (Joshua Rush) and Buffy (Sofia Wylie), a crush, Jonah (Asher Angel), and a sports team, the frisbee-playing Space Otters, represented by Marty (Garren Stilt)
But there's a lot of to watch even in that standard group: Cyrus, who has a big, blatant crush of his own on Jonah.
It's so obvious that it almost looks intentional -- according to rumor, Cyrus is going to be outed as gay in a future episode, which would make him the first overt gay teen character in the Disney universe.
Maybe he and Andi will openly compete for Jonah's affection, thus straining their relationship.
I doubt it. Disney has done a few "my gay moms sort of walk-ons," but continues to promote the myth that there are no gay children or adolescents -- gayness is something that happens to you in adulthood after a hetero-horny childhood. So if there's a gay character, it will probably be Bex.
But there's always next episode.
