Deltarune and Undertale Theories

First Topic

(Spoilers, beware)
So an entry topic by Queenly_JD

"Don't forget. . ."

So I hope you can share your theory and choose whether you'll become a talor or a runer. The screenshot of Queenly_JD's (Sunshine Jaycel) theory is the first theory we'll brunch out of.

Please play the music if you'd like. There's a lot of theories going around this and I hope you'll cooperate, dear theorizers.

New theorizers!

In the Undertale game we see a picture saying *You see Sans and three other people you don't recognize*
While in the Deltarune we see three or four picture of people we do recognize (a bit) so there's some people trying to connect this with the Undertale one.

We hope you'll share your theory with us since there are a lot of conspiracies going around, like how Sans gets this picture so that once he comes back to Undertale he wouldn't forget Deltarune.

In the game, when Sans says he's a stranger, and that we don't know him he winks at us. I'm not sure if Toby just wanted to play with us and laugh at us as we make theories even though it's pointless but many believe otherwise. So what do you guys think?

What was the use of Kris holding that picture with "don't forget"? Go ahead and read the pic while playing the vid.

Undertale, and Deltarune is not mine and neither are some theories.

Now let's start diggin' for theories ;)
