"Oh."
"Yes. There's a poem - we don't have the book, actually, there was a bag of things she had me hide to take with us if we escaped on our own, and it was in that - but she used to read it to me, when she could still read poetry, and it was about us. And it said -
Now the light is round about us,
And the sun to guide our feet;
And along the mountain pathway
Shine the flowers, pale and sweet;
And we pluck us each a blossom
To remind us as we go,
How we went, we two together,
Through the darkness and the snow...
...and there's the obvious thing, if I want a flower name. So. Daisy."
