Link isn't at all bothered by seeing people naked; he was raised around soldiers, for a start, and it just doesn't occur to him to care. Though he's not immune to being attracted to people, and Zechs dripping wet makes the lines of his body more obvious. At least Link is polite enough not to stare. For now.

He shakes his head.

"Peaceful acts, it said," he answers. It's a hard thing to imagine, really. He's never lived in peace. The shadow of the Calamity was over him his whole life, and then things fell apart entirely. Since he awoke from being basically dead and having to heal, he's been fighting. Hyrule wouldn't have peace until Calamity Ganon was defeated.

But he missed what peaceful acts actually means. Isn't this a peaceful act, just being on the shore fishing, helping a stranger? Hm.
