In Chapter 1059 we see a newspaper reports about Koby being captured by the Blackbeard Pirates. The theory I see people talking about the most is Blackbeard turning in Koby’s bounty to Cross Guild and then you get the Alvida reunion. That would be super cool and I think that’s plausible but I think that could still happen on top of the theory I have.
So Kuzan is affiliated with Blackbeard and the prevailing theory is he’s undercover for SWORD. So that interaction is a very big possibility. However, what if another reason Koby was captured is to prove Kuzan’s loyalty? Blackbeard has shown that he knows far more than he lets on so what if he’s already suspicious of Kuzan and he wants Kuzan to kill Koby in front of him to prove he has fully removed himself from the navy.
Kuzan would refuse which leads to the reveal that he actually is part of SWORD so he tries to escape with Coby but is wounded. One of the reasons Kuzan is affiliating himself under Blackbeard could be to try and discover the method that Blackbeard used to acquire two devil fruits powers and how the Blackbeard Pirates steal other powers and before he passes he could impart the knowledge he’s gained to Koby and also give Koby his ice power somehow in the process.
It makes a lot of sense to me if the reason Koby becomes a big part of the story again is because he’s the one who’ll tell Luffy about Blackbeard’s secret. Blackbeard could monologue and tell Luffy during their battle but I think it would be so much more dynamic if Koby was the one to do it. Imagine the panel after a couple arcs where we see Koby again after awhile and he suddenly uses ice powers and he reveals why he has them.
