Sparks gives a mildly affronted huff at being addressed as 'thing'. But since they don't immediately attack or seem prepared for a battle, he doesn't do much else.

Frisk doesn't answer for a moment. A human. That's--that's odd to see, even outside the Underground.

"...he's a Manectric." They must be from another region. Frisk isn't sure exactly where that mountain was. They were pretty sure they were going north when they left Hoenn, but they didn't exactly have a map.

Frisk steps forward, gives Sparks an absent pat along the back (and ignores as his namesake buzzes along heir hand). "D'you know where this--where are we?"
