Bleach 525: Unrestraining of Zaraki Kenpachi

Recap and Comments of Bleach 525: Edges

Zaraki Kenpachi versus Unohana Yachiru battle continues. Zaraki is thinking to himself how nostalgic it is for him to lose consciousness in middle of the fight and how it has only happened once before.

We get a small flashback of Unohana Yachiru, one of her underlings is approaching here somewhere saying that "No matter how much we search through Rukongai I really don't think we'll be able to find someone strong enough to satisfy you", so Unohana is very much alike Kenpachi.

They find a mountain of dead corpses and on top of them a boy with a long sword. Yunohana describes her feelings as losing interest in the sword, in fighting, but this child changed everything.
I think it's pretty obvious that the kid was Zaraki Kenpachi.

We get back to the present where their fight currently happens. They both are thinking their own stuff, Kenpachi feeling alive when coming out of unconsciousness and Unohana thinking how Kenpachi unconsciously restrains himself.

Unohana is hurting Kenpachi over and over to awaken his old self, to awaken his true fighting power to surpass Unohana and go higher and higher..

I have to admit that I'm not a huge Bleach fan, so the things that happen in it don't very well stick to my mind. These kind of chapter sure raise my interest since they are well designed, even if they don't serve a higher purpose. What I'm really wondering is the timing for this to happen, since I can't shake the feeling of Zaraki Kenpachi just getting utterly beat by the Quincy guys and now he's being described as someone who unconsciously restrains himself and his fighting power? I've probably missed something, but it just doesn't make sense. We'll most likely see Kenpachi beating Unohana in the next or the chapter after it and hopefully see an unrestrained Zaraki Kenpachi.
