Frisk meets Gaster Blasters | Cute/Funny Undertale Comics | Week 2 Day 1

Sans' blue eye tells you he knows what Frisk did.

Pretty sure it’s a spellcasting thing...? Could be wrong though I’ve never played genocide lol

I meant he's about to give Frisk a bad time.

Well, yeah, I’m just saying that the blue eye and bad time aren’t necessarily correlated, since the blue eye is an indication of the spellcasting. The bad time, I think, is blue eye and blank right eye, and the comic is blue eye and white right eye.
Idk why I decided to debate this it doesn’t even really matter smh

blue eye and white eye is like medium time
fine time
ok time
decent time

The blue eye is actually tied to the gravity manipulation power sans has. He never actually flashes his eye unless he is using his gravity manipulation ability.
