Father's Day
Episode Synopsis: Kimber begins to realize how much she misses her late father and gets angry at her band members when they ask her to write music for Video's Father's Day video. They take her to a retreat for a day of horseback riding to inspire her, where she is injured and helped by Pizzazz's father, Harvey Gabor. Meanwhile the Misfits are "enjoying" small town life in Clash's hometown of  Mulberry.
