I’ll share mine in the comments.

Somehow Spamton or Jevil would return. Somehow.

This sounds like it’d be a chapter 7 thing

It could, potentially. (You are finally awake from thine deep slumber!)

petaly is real

We might see how Undyne lost her left eye in chapter 3-4 or 5

…Undyne has her eye in Deltarune

Yh. Thats the point. She has her eye there, but in Undertale there is a police badge in sans lab. This implies that Undyne lost her eye one time as a cop

Deltarune isn’t a prequel, it’s an AU

I beg to differ due to this being my personal opinion good sir!

I read a theory about it being a cross between a au that crosses over into being purged and reset into the Main Timeline.

Deltarune proves that Alternate timelines can exist

Noice!

My headcanon: multiple knights

Could happen. Especially since Kris, Gaster, Asriel and Dess are the most likely candidates for the Knight

You forgot about the turtle

Gerson? Didn’t he die?

The other turtle

The one at the church that Asriel confessed Kris’ sins to? (He told on Kris for abandoning Yoshi)

The mayor is also a candidate

Really? In that case, Mettaton might as well be the Knight lmao

Noted.

Yes

Vessel is the knight.

It could be that yes. Personally I think the most likely candidate for the knight is Gaster

Potassium

Kris get the banana

Spamton knowing Jevil makes me wonder if all dark worlds are connected, even if they take place in different locations in the light world.

That would explain how Ralsei can travel between dark worlds

Susie or Ralsei will likely die in the continuation of the weird route

Spamton calls money Kromer because google crome.

The [[kromer]] is a lie.

The dark fountains are like the barrier in undertale and there could be several barriers that are dark fountains and the monsters just don't know it's a seperate world, nor that there are multiple other dark worlds and fountains/dark fountains

Maybe.
