Haruka, Makoto, Nagisa, and Rei swim in their individual events.  Rin becomes irritated as he remembers watching them swim back in grade school.  Afterwards, the four Iwatobi Swim Club members must prepare for the medley relay.
That's why he wanted to race you.
Deswegen wollte er ein Rennen 
gegen dich schwimmen.
Por eso compitió contigo.
Por eso ha competido contigo.
C’est pour ça 
qu’il voulait t’affronter.
Ecco perché voleva la sfida con te.
É por isso que ele queria 
nadar contra você.
Потому и хотел соревноваться с тобой.
