THEY THREW IT BACK! Great! Even if Frisk has to flail over to try to catch it, and doesn't quite manage to do it. They drag it over the dusting of snow and wind up.

"Yeah, would." 'Cause it makes them kind of feel like something's behind them, or that they're too boring to look at. (A thing that wouldn't bother their older self at all.)

And then they say "Catch!" and let it fly.
