PATRON POLL: Which theory is next?

Hello, beloved freaks! As December draws its curtains and January looms ever closer, my holiday break is coming to an end! I'm nearly ready to slam my foot on the gas and get this next theory going - the only problem is, I can't decide which one is next. These two theories have one thing in common: one pesky piece of evidence that's important to both of them, and I'm not sure which video I want to reveal that piece of evidence in. So it's up to you guys! Whichever option wins this poll is the video I'm doing next.

Now, since I know you guys are chill, here are some more detailed explanations for what each theory is, so you're not just voting based off of a title -

FINDING RALSEI'S ABSENTEE FATHER
This is basically my all-encompassing Ralsei theory. It would include my explanation for why Ralsei is a "prince" with no King or Queen in sight, who created Ralsei, who created Castle Town, what exactly Ralsei is (spoilers: he's NOT a darkner!), what his purpose and arc in the story would be, and why I proposed he would be "The Pawn" in my recent video. Also an answer to another question from all the way back in Undertale, but telling you what that question is would be a spoiler.

CONNECTIONS THEORY
Previously I've teased this one as "The Actual Connection Between Gaster and Dess," at a point I was toying with "Findings from the True Lab," but this name is what I've settled on for now. It's not just about the connection between Gaster and Dess, but the true nature of the connection between Undertale and Deltarune. If you're familiar with Mollystars' DEVICE Theory (let's be real - if you're here, you probably are), this theory also includes my explanation for what exactly the DEVICE is.

By the way, this video isn't actually the next thing you'll see from me! I may or may not have recorded something with a certain raccoon. Keep an eye out this Valentines Day! ;)
