Plot hole: All through the movie it is made known they have to get through TeKa to get to TaFiti. They fail and Maui leaves. Moana goes back alone and makes it through the barrier island and Maui returns to help her. The problem is he returns from the direction of TeFiti, if he can do that He could have done it all along, and therefore discovered TeFiti was gone.
