There's trouble at the beach.  The four swim club members are forced to revisit their motivation to swim.  After Rei asks Makoto about his odd behavior during the training camp, Makoto tells them about his past.
Did you see that shadow?
Hast du diesen Schatten gesehen?

de una persona.
Une ombre a bougé par là…
C'è un'ombra umana laggiù.
Vocês viram aquela sombra?
Ты видел ту тень?
