"My body turns to magic when I warp and phase already, and that's through the Crystal's power, so it's not a huge deal that it might absorb me the same way." Even though it didn't hurt when he warped and phased, but sure. Same theory. "You can redirect memories into other crystals?"

The idea that the memories are coming from his head hadn't occurred to him, and that makes him nervous all over again. It would assuage some of the guilt of carrying his own problem by way of the ring, but that also means there's not an easy solution for preventing them from harassing his mind.
