Hi, new guy, just made an account for this topic.

I'm so glad someone mentioned Rukia, Rangiku, etc. recognizing/not recognizing Isshin. I realize he's aged, changed reiastu-wise and whatnot, but I still call bull.

This is just guesswork on my part, but I feel like Aizen and comrades had something to do with tampering/blocking memories of Isshin from the Gotei. Seriously, I highly doubt that no one - not even Old Man Yama - didn't recognize the "punkass ryoka" was the son of a former Captain. That doesn't happen.

Hopefully the next manga chapter will shed some light into this.
