If Natsuki sells Atri, he can get batteries. However, he can no longer think of Atri as just an average humanoid. While he's deep in thought on the dock, looking out at the ocean, Natsuki finds Catherine floating in the water. She is completely intoxicated, and Natsuki and Atri take her in. But right at that time, the sound of a gunshot echoes within the silent ship.
And when it's low tide, 
the water will recede from the hole.
وعند المدّ المُنخفض، سينحسر
الماء عن الحفرة
Genau. Und bei Ebbe
fließt es wieder zurück.
Y en marea baja,
saldrá agua por el mismo agujero.
Y en marea baja,
saldrá agua por el mismo agujero.
Avant de ressortir par celui-ci
à marée basse.
E poi, con la bassa marea,
E na maré baixa, é claro,
a água vai escoar pelo buraco.
И, разумеется, уходить во время отлива.
