in this movie most of the time, Nami is with Zoro
There is a scene with Zoro&Nami in which Uta with her song magic power, send a bottle of sake to Zoro (nami is with him)
There is a scene when they awake, and basically Nami is sleeping next to Zoro
Like toei could at less put nami next to luffy after they awake (after they have defeeated the Uta legendary monster)
