In order to procure water, the girls explore the island. Homare and Asuka find a dry stream bed. In order to get water from the dirt they dig up there they'll have to...!?
Meanwhile, left behind on the beach, Shion and Mutsu, both faint from dehydration, make a certain promise...
When it rains, this must become a stream.
يصبح هذا تيّاراً عندما يهطل المطر
Esto debe convertirse
en un arroyo con la lluvia.
Esto debe de convertirse
en un arroyo con la lluvia.
À chaque pluie,
une rivière se forme ici.
Credo che si formi un corso d'acqua, quando piove.
Quando chove, deve virar uma correnteza.
Но наверняка только во время дождя.
