Makoto and Nagisa watch with their breaths held as Haruka and Rin engage in an intense race.  However, they notice that Rin appears to be have changed. At the same time, Nagisa prepares to start up a swim club with help from Rin's sister Gou.
We won't be doing this by ourselves.
Wir werden das nicht alleine tun.
No vamos a hacer las cosas solo nosotros dos,

Nous ne faisons pas ça 
tout seuls.
Non riguarda solo noi.
Não iremos fazer tudo sozinhos.
Там же будем не только мы.
