Coach Sasabe begins training the Iwatobi Swim Club for the upcoming tournament. Meanwhile, Rei is unhappy about the fact that he's the only one who doesn't know about what happened with Rin in the past.  After Rin expresses his frustration, Haruka decides to tell him about what happened when they were in grade school.
Then why did you give it to him?!
Warum hast du es ihm dann gegeben?!
¡¿Por qué le diste eso?!
¿Y por qué le diste 
una cosa caducada?
Pourquoi lui avoir donnée ?
E perché gli hai dato una cosa simile?!
Então por que você deu para ele?!
И зачем ты дал его ему?!
