That's it, I'm completely convinced now. Kaido has a soft spot for his daughter which is why he respects her wish to be called his son, which is why he went to Marineford to save Ace after she had asked him to, which is why he tries to die in a flashy way like Oden, which is also what him wanting to ask the scabbards something about Oden is all about. He wants to ask them what made Oden so special because he wants to be admired by his daughter, too. While Momo struggles with living up to his father Oden, Kaido struggles with living up to the expectations of Yamato.
