Batgirl's best friend Harleen moves to Metropolis, but doesn't gel with her new group of friends, and is soon hanging out with a less savory crowd...
Tropes:
- Anachronic Order: This episode would seem to take place before "#Beeline" (where Harley Quinn already lives in Metropolis and is a member of the Super Villain Girls, which both happen here).
- Bizarre Taste in Food: Barry comes up with the idea of trying toffee and jalapeño on ice cream. Babs for her part can like the toffee or jalapeño separately, but can't handle both. This inspires an epiphany over her friendships.
- Chekhov's Gun: Teased, but then averted. In the course of the brawl Batgirl and Harley Quinn both get a telltale injury that's meant to make you think will tip them off about the other's secret identity. They do notice when they hang out in their secret identities and start getting suspicious...then they get distracted, forget about it and the episode ends.
- The Friend Nobody Likes: None of Barbara's super hero friends like Harleen. Barbara learns she can still be friends with people who aren't friends with all her other friends.
- Instant Convertible: Giganta rips the roof off a car, which the Super Villain Girls use as their getaway vehicle.
- Mailbox Baseball: Harleen takes Babs out on a ride with the Super Villain Girls, who indulge in mailbox baseball. While Babs leaves early, Harleen not only joins them, she does them one better by blowing up a post office.
- Mrs. Hypothetical: Star Sapphire writes "Mrs. Star Sapphire Jordan" on a museum's wall.
- Not Brainwashed: Babs uses Diana's lasso of truth to force her friends to confess how they really feel about Harley. Kara's shocks her the most because she wasn't even bound by it.
- Pungeon Master: Harley when fighting the Super Hero Girls. She even lampshades it when she's dragged away and complains that she was going to hit Batgirl with a board and say "Sorry if you're board!"
- Screw This, I'm Outta Here: The Super Villain Girls retreat when the police arrive, although Harley has to be dragged along because she still wants to fight.
- Transformation Sequence: Each of the Super Villain Girls and Super Hero Girls get one.
- Vanity License Plate: The car the Villain Girls steal has the license plate number BRN 2 BBAD note .
