How did you know I would respond to this? :P

I don't think it's that much of a problem to Kubo. All the talk about collecting data on Sui-Fêng and the great knowledge he had about her only points towards 1 epithet, as I see it, and that is "The Knowledge", or another form like "The Know" or "The Knowing". If he's killed in the next chapter, I think his epithet will be revealed, be it before or after his death. After all, the 3 Sternritters Kenpachi killed, were introduced after their deaths. Shaz is the only Sternritter who have died, whose epithet is still unknown.

Regarding Bambi, he introduced her as Sternritter E in the very first panel where we see her face. Maybe he wanted to make her a character who loves to cut down people, and later changed his mind and got the idea of "The Explode". This could be a possible reason as to why she's never used her broadsword spirit weapon since the first invasion. But cutting down people doesn't have to be related to her epithet at all. He's displayed her as a person who loves to kill people, by sword and by turning them into bombs with her reishi. The look on her face when Momo attacked her from behind, was pure sadistic. This is probably all there is to it.
