[Winnie] wished, for a fleeting moment, that she could stay with them forever in that sunny, untidy little house by the pond. Grow up with them and perhaps, if it were true about the spring—then perhaps, when she was seventeen . . . […] And then her eyes went to Tuck and lingered on his sad, creased face.

"Anyhow, I come to say goodbye. We won't be able to come back here for a long, long time, Winnie, if we get away. I mean, they'll be looking for Ma. Winnie, listen—I won't see you again, not for ages. Look now—here's a bottle of water from the spring. You keep it. And then, no matter where you are, when you're seventeen, Winnie, you can drink it, and then come find us. We'll leave directions somehow. Winnie, please say you will!" (22.20)
