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.
But then I watched you guys swim.
Aber dann sah ich euch schwimmen.
Pero entonces vi la competencia de ustedes...
Pero entonces, os 
vi nadar a vosotros.
Mais après, je vous ai vus nager.
Poi ho visto le vostre gare.
Mas aí eu vi vocês nadarem.
Но тогда я увидел, как вы плывёте.
