1) Bad translation it seems. It most probably means they attacked Big Mom's ship then ran away to this island but rather than staying on the Sunny they went to take a look on the island.

2) When Nami and Brook fall to the ground they mention "it's probably thanks to that girl's powers that we lost them"
