You must not let me out,' it warned him gently, as it saw his eyes rest on the lock.'If you release me now that I know my nature, I could not help but unmake the enchantment of the mirrors. You see, they are tame now and they show only what people want and need to see in them. The wildness of them is bound up in my form, though I did not know it for a long time. If I were uncaged, I could not help but tear at the enchantment until I was unnamed. Then I would fly into all of the mirrors and windows and into shining footpaths after rain. The mirrors would become wild and they would be absolutely, utterly truthful. Everything would be seen for what it truly was. My laughter would greet every lie and every pretense. It would rumble like a volcano under the smooth surface of everything. You can imagine the chaos it would cause here, for those who dwell in the greylands do so because the mirrors are tamed. If I were free, people would come to be afraid of them. They would cease to believe in their reflections and eventually they would no longer believe in themselves. No, laughter must remain caged here.
