Rukia may have gotten her powers back but due to her confinement in that holding cell she still has not regained enough spiritual energy to do anything. That is clearly explained and it takes time to regain all of those powers. She is surprised that Ichigo has reached Bankai because he went from near dead to learning Bankai in less than 2 weeks. That is completely unheard of when it has taken everyone else years to learn it.

I still say she has it. I am still at work so I can't reply about Kenpachi yet. To help move things along on that front does anyone know what episode or chapter someone mentions that Ichigo's Soul Slayer is special in that it is always in mode 2?

On an awesome side note....Death God Illustrated Guide Golden is always hilarious. I can't wait for more of that intense soccer match next week XD
