I suppose Gehenna is only using Chaehee to cook and do the menial housework. She's gotten pretty comfortable in her unreleased, low-corruption mode.

The new girl must not be allied with anyone, since she thinks the Teldar are ghosts, but I was half-hoping that the student-teachers wouldn't end up being other Teldar. It's a bit of a letdown that all three of them were.

Still, Inferno and Shichan have been pretty good at killing any non-Emperor Teldar that figure out who they are. I don't remember whether or not Pandemonium knows what body Inferno possesses. He certainly knows Gehenna, and Thanatos probably could identify Inferno, but all the times they've met (to my knowledge) Gehenna and Inferno were released, and they look considerably different in those forms. Gehenna has much longer white hair (but wearing the school uniform gives her away). Inferno on the other hand, made Shichan look dramatically more feminine when she took over after he passed out.
