After arriving in Fremantle, the girls get a tour of their icebreaker ship. When Gin mentions that their new room was where Shirase's mother once stayed, the girls check to see if she might have left something behind there...
Oh, there's also a rule: 
Don't step on the silver part here.
،صحيح، هنالك قاعدة بالمناسبة
.لا تدسن على الأجزاء الفضّيّة هنا
Ah, procuren no pisar
esta parte plateada.
Ne vous prenez pas les pieds
sur la partie argentée.
Ah, dimenticavo. Non mettete i piedi
su questa parte argentata, è una regola.
Ah, a regra aqui é não
pisar nesta parte prateada.
Ах да, у нас правило —
не наступать на эту серебряную штуку.
