“This may be the last time you fly. I can see a little ahead; I can see that you will both be able to climb this high as long as there are trees this size; but I think you will not be birds when your forms settle. Take in all that you can, and remember it well. I know that you and Lyra and Will are going to think hard and painfully, and I know you will make the best choice. But it is yours to make, and no one else’s.”
