In Samoa, Gabe investigates communal building traditions, lashings, cyclone knowledge, repair, and the shared work that allows an open structure to remain strong. Sina is confident, rooted, funny, and unimpressed by Naya's old belief that being welcomed quickly is the same as belonging. A construction-pattern Crossing reveals responsibilities and promises carried through repair gatherings. The mystery forces Naya to define what belonging actually demands: not only welcome, but honesty, recurring work, and people who expect one another tomorrow. The road ahead may depend on whether the family has built a life strong enough to return to.
