1x23 - The Melancholy of Haruhi Suzumiya

As the SOS Brigade continues filming, Haruhi has Mikuru thrown in a polluted lake by the extras. Tsuruya offers her place as a filming location, where Haruhi dresses Mikuru in a revealing nightgown and spikes her drink with alcohol as prep for a romance scene with Itsuki. Furious at Haruhi's shabby treatment of Mikuru, Kyon argues with her and tries to hit when she insists on having her way. Itsuki stops him. Haruhi becomes depressed by her falling out with Kyon. After becoming irritated by Taniguchi's rude comments about the film, Kyon tells Haruhi he is newly resolved that they finish the film, which reinvigorates her. As filming resumes, her powers start causing cherry blossoms to bloom out of season.
