"...Arn," Link says softly. Is it...familiar? Does it spark any kind of memory, any deep-rooted association?

He's not sure. Maybe he needs more than a name, to really remember. But he'll make sure never to forget it again, now he knows it.

Then he looks back at Zelda.

"Don't say that," he says. "You saved me."

He lost all his memories, yes. But the only other option was death. She shouldn't apologise for making that choice, not ever.
