Larissa (Freema Agyeman) returns from her summer in Kyoto and insists on taking Carrie (AnnaSophia Robb) and Walt (Brendan Dooling) to a fabulous Japanese festival in the city, where Larissa meets Samantha (Lindsey Gort), with an explosive result. Samantha seduces an acrobatic Ninja. Back in Castlebury, Carrie's plans to remain Zen backfire when she finds herself locked in a classroom alone with Sebastian. Mouse (Ellen Wong) helps Maggie (Katie Findlay) with her college applications, but Maggie is distracted when somebody from her past reappears. Meanwhile, Walt (Brendan Dooling) worries that his classmates will sense he is gay, and Harlan (guest star Scott Cohen) makes an offer Tom (Matt Letscher) can't refuse.
