Yes. He's fighting Kaidow. Although, how long can the battle be? It depends on how we look at it. If we see it as a distraction for WB to get away, then he's probably still fighting him even though WB already bailed. However if we see it as a friend helping out a friend (aka, Shanks helping WB) then he's probably still making sure he's staying where he is, and most likely a crazy battle by now. There's also a third way to look at it. If Kaidow came to attack WB and stop him, and WB has so many ships to spare, then he probably left some behind in the new world to help Shanks hold him off as a thank you. And, there are 14 division captains there with him now at marine ford. Wb's total crew has 16. Which means that he must have left two behind for shanks or something.Originally Posted by Assertn
Another thing to consider is that Kaidow is a yonkou so he's been around the new world and grand line for years now exploring and building a crew up to become a yonkou. So I'm thinking (and once again just a thought) that he knew about Aces true bloodline and wanted to stop it from getting any further and stop Ace from becoming the PK. So he tried to stop WB's crew from going to protect Ace and stop the execution. That way he lets the government to the dirty work for him and he can stay in the NW looking for new places and progressing without having to worry about Ace.
