I think it could be either that Imu is watching over Kuzan and/or using him to spy on the Blackbeard Pirates. Maybe unbeknownst to Kuzan.
Poor Kuzan if that's the case.

I could see Imu personally, secretly reaching out to a wounded Kuzan after PH and convincing him that there's much more he could do to save the world without being FA, such as spying on and assassinating a certain pirate....
....also if Imu somehow turns out to be a chick that makes it twice as likely since Kuzan's the second biggest horndog among the Admirals after GB.
Ofc there's also the possibility that Wuzan is a triple agent who's double-crossing Imu and BB at the same time. Let's see.
