Sparkle! The Great Pretty Cure Scouting Plan

After encountering Homare earlier, Hana thought it would be a good idea to see if she would consider being a Pretty Cure herself. She and the others meet up with her and notice her taking care of a stray dog, which she rescued from being ran over by a truck when the time stop that both Hana and Saaya experienced occurred. Homare also develops a liking for Hugtan. The group then takes notice of a group of bullies picking on the other students on a basketball, so they challenge the bullies to a game. Just as Homare is about to score a basket, she remembers something traumatizing involving her leg and inadvertently passes the ball to Hana, with her scoring the lucky basket. What had happened to Homare in the past?
