"I've got a wall in my mind," Daine replies. "It keeps my wild magic from getting tangled up with who I am, like it used to be." She's not sure if the same thing would work for Yuri, and without Numair here, it might be a moot point, anyway. Then she remembers that there are other folk here who can poke around minds without much trouble. "Maybe the Doctor or the TARDIS could do something like that for you. What you have is sort of like wild magic, so it might behave the same way if we tried to block part of your mind off from it. You'd still turn into a bear, but it might be easier to remember who you really are." She shrugs, not wanting to get his hopes too high despite her own cautious enthusiasm for the idea. "Meditation helps, too. I could teach you."
