Prefecturals are over and the Iwatobi Swim Club members are pleased by the progress they have made.  A local summer festival gives them an opportunity to relax.  When Nagisa finds out that Rin is also at the festival, he orders Rei to follow Rin and make sure that Haruka and Rin do not meet.
how it felt to swim in the 
same lane together,
wie es sich anfühlt, zusammen in derselben Bahn zu schwimmen,
qué se siente al nadar 
juntos en un mismo carril,
lo que se siente al nadar 
por la misma calle.
de ce que ça fait de nager ensemble 
dans un même couloir
cosa vuol dire nuotare 
tutti insieme in un solo percorso
como era nadar na mesma raia juntos,
каково это — плавать
по одной полосе с вами,
