"I don't think it'll matter if I tell you," he replies, even though he sounds like he wants to. Instead, he holds out the sunglasses for the angel again, an earnest look on his face.

"Can you do me a favor? Hold onto these."

It might not be much, but maybe they'll help him remember at some point. Ferran doesn't like the idea of forgetting someone close to him, and he wouldn't wish it on anyone else either.
