There's a new substitute teacher in town - Mr. Harlow (Ennis Esmer) - and he wants the kids to do improv games! No script! Baxter and Jackal are totally psyched, but Emma's freaked out - she's terrible without a script, especially when there's pressure to be funny. And it only gets worse when Harlow puts the three of them in an improv competition against a rival school! Jenna tries to sabotage Tassie's crush on Marcus, but her strategy backfires when he asks Tassie to the improv games. During the competition Baxter sees his crush Tassie with Marcus and freezes, forcing Emma out of her shell to save the day. Deven is paired with the dance program's prima ballerina - Olivia, and he keeps dropping her. Whoops!
