So what I want to know is why it is that I can no longer find you, in my mind. You are still there, just, but you are there like a ghost, a will o’ the wisp. Not long ago you burned–your heart burned–in my mind like silver fire. But after that night in the inn it became patchy and dim, and now it is not there at all.””Could it be that the heart that you seek is no longer my own? I have given my heart to another.””The boy? The one in the inn? With the unicorn?””Yes.””You should have let me take it back then, for my sisters and me. We could have been young again, well into the next age of the world. Your boy will break it, or waste it, or lose it. They all do.””Nonetheless, he has my heart. I hope your sisters will not be too hard on you, when you return to them without it.
