I think what Shunsui said was taken out of context. I think what he meant was since their personalities are both so deadly that odds are they might kill each other. Plus Unohana is the only one who can train Kenpachi, so killing her off so fast would make no sense. Also, Unohana's Shikai heals and she's an expert healer so she would be able to heal herself quite easily. Plus comparing her battle scar to all of Yamamottos would be evidence off that. I find it hard to believe that in the over 2000 years she's been around, she has only dealt with one major battle wound. Also she has yet to reveal her Bankai, and Kubo seemed intent in revealing all Bankai this arc. Plus I have a crack theory on Aizen (not the one discussed in chat), but that's not for here.
