With a big dance approaching, FOMO's everywhere: Missy misses school, Matthew dives into the deep end — and Andrew suspects that Other Andrew is evil.

Jessi and Jay pair up to parent a melon "baby," Missy faces her fears, and Nick and Other Andrew try to fit in with a group of ultra-rich kids.

After Nick has a sudden growth spurt, Ms. Dunn takes the class inside the body of a teenager to learn about the wonders of puberty.

A reckless Lola gets behind the wheel, and Jessi and her mom have a really big fight. Nick's mother finds his "special shirt" while cleaning his room.

Depression Kitty convinces an anxious Jessi to care less. Nick attracts Devin's attention, and the Robotics Club takes an overnight field trip.
