"No, but if I did, nothing would happen except people being angry at me. ...Maybe it's a free will thing."
"What if - what if I turned you into a bird. What would you do if you were a harmless, little bird?"
"I can't let you go if you're going to hurt Elves," she murmurs. "Or bring information to Melkor."
"I'm trying to think of a way to make it so you can't, but don't have to die. That's better, isn't it? Right now you aren't hurting elves but you're glad you don't have to provoke me into killing you?"
"They haven't sworn to. Well, not most of them, anyway, some of them might have, but most haven't. They could stop if you stopped."
"Not unless you and I think of something," she says, "no."
"Elves don't marry or have children in troubled times," she says. "There are only so many Elves now. But if orcs weren't attacking them, they would calm down, and there would be many, many Elves, and even without orcs around they would find things in their lives that hurt them; and eventually they would die, because eventually they would meet with accident or violence from some non-orc, or they'd fade away; and this could be billions and billions of Elves, over long enough, which would otherwise never be born to hurt and die."
"Well, you couldn't do that if you were a bird, could you? You couldn't carry them."
"Being a bird isn't bad, you know, they can fly. And I can't let you bring any Elves back to Melkor."
"It's true," she acknowledges. "It's not fair; and nothing in your life has been fair; but I still can't let you bring Elves to Melkor."
