I think either Sabo will consume eat or Mugi will destroy it. Why will he destroy it? It'll be great character development on his behalf. How? If he destroys it, it implies that he doesn't need a fruitlet alone Ace's fruit to remember him. He is in his heart and soul and doesn't need the actual thing to prove he cares for him. Alot of people argue that Mugi hasn't developed as much as he should being the protagonist so with him destroying the fruit, it will truly show his development as a main protagonist. But I don't know how he'll destroy it, Goda can definitely think of something .
