The Iwatobi Swim Club needs one more member before it can participate in relays.  Nagisa has set his sights on his classmate Rei, who is a member of the track team.  Despite Rei's refusal to join, but Nagisa appears intent on recruiting Rei into the swim club.
So it's meaningless if we 
can't find another member...
Also ist es zwecklos, wenn wir 
kein weiteres Mitglied finden...
Entonces no tendría caso solicitarlo.
Pues tal y como estamos ahora, no 
tendría mucho sentido hacer la solicitud.
Il faut donc absolument 
un autre membre…
Quindi non ha senso finché 
non abbiamo un quarto nuotatore...
Irá tudo por água a baixo se não
conseguirmos achar outro membro.
Значит, всё бесполезно,
если не найдём ещё одного...
