After years of mystery...
Have we finally learned who the three figures drawn on the card in Sans's lab are?
Noelle, Susie and Kris
OR
Kris, Susie and Ralsei
"Don't forget" as in, don't forget [to give these three a discount]
Even if the reason why Sans has this card turns out to be incredibly simple, doesn't this also confirm that Sans Undertale = Sans Deltarune?
At first, this discovery felt incredibly ironic, since for years we tried to find a much deeper meaning behind who these three figures were and why Sans kept this card in the first place. We thought about Gaster, timelines, parallel worlds, and with the release of Deltarune, we even considered both of the possibilities above
And in the end, the reason why THIS SPECIFIC MESSAGE exists on a card with THIS SPECIFIC TRIO was something as simple as a reminder to offer a discount
On the other hand, the fact that Sans still keeps it with him could be his way of refusing to forget the people, the place... and of not letting the world he once saw as his home disappear
After all, Deltarune keeps returning to the same theme in almost every chapter. Someone trying to make things go back to the way they used to be, unable to let go of the past. Only to eventually learn that some things can't be restored, and that the best thing you can do is simply let go
