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.
But if you're interested, 
I can tell you what happened.
Aber wenn es dich interessiert, kann ich dir erzählen, was passiert ist.
si quieres saberlo, te lo contaré todo
pero te lo contaré todo 
si quieres saberlo.
Mais si tu veux savoir,
Ma se vuoi saperlo, ti dirò tutto di noi.
Mas se você estiver 
interessado, eu posso te contar.
Но если тебе интересно, могу рассказать.
