Unless Mokuran is incapable of thinking herself, Ebon's telepathy only picks up surface level thoughts. He can't go rooting around for memories. But he can tell how your mind is somewhat working, discerning mood, motives, internal monologues, and focus. If he asks you what your name was, even if you don't tell him he should be able to pick it up if you think your name for even a moment. I liken his power sort of like Nodoka from Negima, though he doesn't need a book or multiple artifacts.
