"I know. I know. It just--it hurts so much, losing that."
She shows him memories.
Being five in Kilaiuossa, carefully cradling a baby doll, getting patted on the head by a neighbor and told she would be a wonderful mother someday and glowing with pride--
In Valinor, in Tirion, before Melkor started spewing hateful prophecies, discussing what a hybrid baby might be like and bubbling with delight--
Cuddling a baby dinosaur and hearing from him that she would be the best mother ever--
Alive again, and seventeen, and knowing that there was no merciful got but begging anyone who would listen and didn't hate her anyway that she would manage to fix aging and live long enough to rescue him, and one of the things that came up was, please, I'd be such a good mother, you know I would, give me a chance--
Learning blond wasn't his natural hair color and commenting that it was a good thing she had learned before they had children and imagining herself holding a black-haired baby, her husband's arms wrapped around the both of them--
"I'm not sure how much more I can stand to lose."
