Preparation for the SOS Brigade's short film continues, with character roles revealed—Yuki as an evil alien, Itsuki as an esper, and Mikuru as a battle waitress from the future. Mikuru is forced to dress in an embarrassing waitress costume for her role, while Yuki appears as a witch. On the first day of filming, the Brigade film two commercials to advertise their sponsors with Mikuru dressed in her waitress costume and then her bunny girl costume, much to her embarrassment. They then film several scenes in a park, and Kyon points out that Haruhi did not actually write a script.
