There's a moment of heavy silence. Link's face tends towards showing little of his thoughts and feelings even in the best of times - add in the veil, and it's possible to tell exactly how he's feeling in response to this question.

But lack of a response perhaps says everything.

"...How do we solve things here?" he says, eventually. Because if there is a way back home, then Link needs to find it.

He can't leave Zelda alone. Won't. Not after everything that happened.
