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.
We should have worn ours.
Wir hätten unsere tragen sollen.
Nosotros también debimos ponernos una.
Nos tendríamos que 
haber vestido así.
On aurait dû en mettre nous aussi.
Sarebbe stato bello venire 
qui anche noi in yukata.
Nós devíamos ter vestido as nossas.
Нужно было и нам надеть свои.
