Confirmation from bitchysix (rumored informant for Hannibal productions) that season 3 wont feature Murisaki – only Chiyoh.

Which actually might be more good news than bad.

1. The decision erradicates the fear that Murasaki might be aged down for superficial purposes through Tao.
2. The character is most likely being saved for when Bowie is available for Robertus – and I think everyone can agree Robertus is nothing but boring without Murisaki 😀
