Theory: Zaza fruit hasn't been eaten yet

Let's straight some facts, if Dragon has already eaten the fruit makes 0 sense to him not making any move as the CD feel so much fear about it. For me, I think the treasure of Mariejoa that Doffy talked about i think is tha Zaza fruit, makes a lot of sense for they to have control of the fruit that could destroy them, and makes more sense when Oda already told us the "Gomu" Fruit was in hands of the WG already. Giving the current world state of Mariejoa (and it is not confirmed but in some pannels it seems like they were under attack) of low supplies and weakened, i think Dragon will atk and somehow steal the fruit. It is so curious also that Vivi is stranded with Morgans who i think is somehow a part of the Revolutionary or at least take Vivi to them and she will eat the fruit.
