User blog comment:Primeramizery/What could Mayuri be working on in his lab?/@comment-11051098-20130707185420

Akon looked like he was completely shocked by what he saw on the camera he had installed in Mayuri's room. My guess is that for Akon to be shocked by Mayuri's doings, having been in the squad with him for more than 100 years, it has to be something illegal, lol.

Like, perhaps experimenting with Unohana's body, trying to resurrect her.
