It has been mentioned many times already that there could be a mole among the Kozuki clan's followers, possibly even one of the Scabbards given how easely the Beast Pirates were able of knowing Zou's location and of knowing that Raizo was here and that Kaido caught word of Oden and his scabbards' attack on him during the flashback.
But what could possibly be the motivations of this traitor if he/she really exist ? For what reasons could the traitor obey Kaido and Orochi ?
Could it be out of a honor debt ? Or rather because the traitor is from a family that was wronged and/or was ennemy with the Kozuki clan too ? Could he/she be forced to do that ? Other reasons ?

Izo is a grown man by the time he left with Oden. He's capable of making decisions on his own. If Kiku can't respect his wishes, that only reflects poorly on her.
