It's not reasonable to love people who are only going to die," she said.
Nash thought about that for a moment, stroking Small's neck with great deliberation, as if the fate of the Dells depended on that smooth, careful movement.
"I have two responses to that," he said finally. "First, everyone's going to die. Second, love is stupid. It has nothing to do with reason. You love whomever you love. Against all reasons I loved my father." He looked at her keenly. "Did you love yours?"
"Yes," she whispered.
He stroked Small's nose. "I love you," he said, "even knowing you'll never have me. And I love my brother, more than I ever realized before you came along. You can't help whom you love, Lady. Nor can you know what it's liable to cause you to do."
She made a connection then. Surprised she sat back from him and studied his face, soft with shadows and light. She saw a part of him she hadn't seen before.
"You came to me for lessons to guard your mind," she said, "and you stopped asking me to marry you, both at the same time. You did those things out of love for your brother."
"Well" he said, looking a bit sheepishly at the floor. "I also took a few swings at him, but that's neither here nor there."
"You're good at love," she said simply, because it seemed to her that it was true. "I'm not so good at love. I'm like a barbed creature. I push everyone I love away."
He shrugged. "I don't mind you pushing me away if it means you love me, little sister.
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.
