Now I'm very interested in seeing what was in the note Retsu left Isane. She seems rather glad that she is dead, or at least that she was able to pass on her name before dying. Also, the emphasis on her saving the captains' bodies would seem to imply that they are not truly dead.

And unfortunately, Unohana seems to be dead... but here's to hoping for a The Undead 5.
