Margulis already has some tech that can read nerve impulses, so he'll go ahead and sign up to be sure they won't interfere with each other.

But because of the game he came in from, he has an entity in his head that's part of him but also distinct enough for them to have mental conversations. (A Persona, to be specific.) Would the ring be able to pick up what she's saying and would she be able to use it normally or only accidentally by malfunction?
