When Phoebe discovers Link's friend Quinn is a dangerous villain who wants to keep him all to herself, she enlists Max's help to expose her. Meanwhile, Billy and Nora become roommates and think a monster is in their newly shared room.
Tropes:
- Bitch in Sheep's Clothing: Quinn seems nice on the outside, but is really an evil bug villain who wants Link all to herself and Phoebe to be gone.
- Cassandra Truth: Link doesn't believe Phoebe when she tries to tell him about Quinn's jealousy, while Hank and Barb don't believe the twins when they think there's a monster in their newly shared room.
- Chekhov's Gun: Link mentions near the beginning bug villains can't resist the scent of mangoes and their weakness is hot sauce. On their date, Phoebe uses the former to expose Quinn's true colors in front of Link, and the latter to defeat her when she closes in on Max.
- "Getting My Own Room" Plot: Inverted; Billy has to move into Nora's room and become her roommate when Chloe is moved into his room. The twins are excited, but Chloe doesn't want her own room because she thinks there's a monster in it. When the twins hear growling noises and the parents don't believe them, they set up a booby trap and the noises are revealed to be coming from Chloe's doll, because she had been teleporting under their beds every night due to her fear. Barb moves Chloe back into the parents' room until she's ready, and allows the twins to keep their shared room.

Phoebe: Oh! Oh! I know! Uh, see, this is the moment where you realize your girlfriend was right about your friend being a bug villain!
