I thought wapol is already has a happy life after becoming a CEO of the toy factory and having the hot chick by his side, is that possible for him to turn against strawhats again?
Movie 9 is more or less of a recap(if it's a recap at all). As for Wapol, I suppose that he's happy now. Maybe he will turn bitter against the Straw Hats like Buggy and Foxy, who knows. But my bet is that he would run away at the first sight of straw hat nowadays.
