actually not a rhetorical question. Literally why would anyone talk to Hiyori]

Don't get me wrong. If I thought there were even the slightest possibility of the pretty picnic you're imagining that all the past games actually ended in, I'd be acting very differently. But you're not buying anything we're selling! So it doesn't matter. I'm sure Link will be preparing the sandwiches right on schedule.
