Ever since Nagisa came back, Tomoya has been pretty happy, and the girls noticed that. Then, at some point during Tomoyo's tennis match, the guy Tomoyo was playing with hit a ball, and it ended up hitting Nagisa's leg. The guy said she had to be taken to the infirmary and intended to help but, Tomoya didn't allow him to, and took Nagisa to the infirmary himself.
The girls noticed that. Kyou pretended as if everything was fine, and acted relieved because Nagisa's wasn't a serious injury. Ryou apologises to her but, Kyou said everything was okay. After that, she started crying, and Ryou followed her. Tomoyo ended up looking at the sky.
