That's it. I believe that Edward Weevil will join the God's Knight, while Donquixote Doflamingo will join the Cross Guild, and below i will elaborate my arguments for this theory. Enumerating the parallel between them: 1st, Doflamingo: was born in a noble place (Mariejois), while Weevil presumably was born in a place as humble as his father, White Beard was. Doflamingo: Is mischievous, knows a very important secret, is uncontrollable. 2nd, Weevil: Is the complete opposite of our former joker, a perfect candidate to be easily controlled by the Gorosei to do their bidding without questioning, not to mention that having a prime White Beard level of power house is not a thing they would want to let go wasted, right? 3rd: While Weevil has immense respect and affection for the father that he never met, Doflamingo immensely despises his own father, to the point of having killing him. 4th: Doflamingo was a noble that fell from the graces of the world government and had to become a pirate, while is Weevil is a strong candidate to be a pirate that will rise to the post of a Tenryuubito (God's Knight), specially tha now he is separated from Mrs. Bakkin, he will be easily manipualted by the Gorosei/God's Knight to to their bidding. How and where will this all happen? Impel Down is where this all will happen (both characters are currently there, and such events are what will lead the Cross Guild to directly confront the God's Knight and force Buggy to join forces with Luffy and the Revolutionaries once again. The Cross Guild will have an interest in Doflamingo and they will storm Impel Down to recruit our psycopath knitter and he will gladly join them only to see the world burning, not to mention that he will be finally working together with our Croco Boy, and we will possibly see Mihawk vs Figarlang Shamrock, the closts of a Mihawk vs Shanks Oda will give us. This, will certainly leave the world government with a bitter taste of defeat and will mark the Cross Guild as a maximum level of threat, and the Cross Guild will have to protect mingo from the evil gorosei, in change of learning whatever secret he holds, not to mention that their bounties will significantly rise. Weevil's final role: He will actually be recruited by the world government as a consolation prize, but during the final war, his mother, that will likely have joined the White Beard Pirates (or whatever new name they are given), will convince her son to change of side and fight for the "justice". Weevil will then realize that he was being fooled by the world government and will front stab them (The reverse of what Squalo did, fooled by Akainu to attack White Beard). After knowing all of the truth from the White Beard Pirate's remnant, he will possibly side with Luffy and Koby to fight Black Beard, or at least, fight his servants/crew mates. Worthy noting: Let's pretend that i nailed all, or at least, most of what i wrote here, for this all to happen, there should be another available vacancy on the God's Knight, what means that someone else would have to leave the group: Who could it be? Gunko? Is she a spy of the Revolutionary Army? Not impossible, asDragon would need intel information to know when and where the God's Knight will make their next movement, but my best bet is that a possible traitor is no less that the character that we just got introduced to: Limoshiff Kirigham. But why am i so rushed in trying to predict the role of someone that we just got introduced to? His introduction itself is a great indicator of what makes me believe that he is a traitor, or will be: He was already introdcued in his hybrid zoan form, and had the white smoke pattern around his neck, a pattern that only characters whose moral aligment are considered to be good were shown so far: Luffy and Yamato, while all those that had a black smoke around their necks are considered to have an evil moral alignment: Rob Lucci, Kaku, the gorosei and Figarland's sword Cerberus. What the Kirin represents? Goodness, wisdom, purity, good luck and justice, all these charactertistic go against what the government does to the Blue Planet, so i think that until the end of Elbaf, or somewhere shortly after it, Kirin will betray the God's Knight, possibly after seeing the events of the Native Hunting Competition that is about to happen, and will leave an open vacancy for they to try to recruit Doflamingo. Remember that Imu is not iniscient, so there might be more people like Mjosgard (Rest in peace) in Mariejoa and rest of the Donquixote Family, good people, trying to change the world from above.
