I'm pretty sure the last prophecy panel reads "Their castle town must be sealed away" or something to that effect. Any thoughts?

In the beginning of Ch.4 Susie says "they took undyne to the shelter, the real shelter"

what? huh? what is she on about? does she know about Mantle?

I feel like the overarching story that seems to be forming around Sans doesn’t seem to be getting its due diligence. Yes, sure everyone freaked out over the rain and the punch card, but nobody else had the same mental breakdown I did when I tried thinking about the font family’s timelines deeper.

Sans, its seemingly confirmed now, comes from Deltarune first. “Its raining somewhere else”, the punch card and (maybe) the bleeding seemingly cannot get enough of telling us “Sans was here before Undertale”. Which got me thinking.

what is Undertale?

If sans comes from deltarune, to undertale, then his timeline is seemingly the reverse of gasters. Gaster pretty famously, was shattered across space and time in undertales past. Sans starts in the deltarune device, and moves into undertale to have the punch card. Genuinely asking for help figuring this out because how does this work? I don’t doubt Toby will elaborate on this in chapter 6 or the finale but to me sans seemingly develops sentience in the experiment, figures out how to jump realities out of a simulation and into the world of undertale, which as far as I understand it, isn’t simulated. Gaster shatters, creates deltarune and thus sans, sans leaves deltarune to undertale, and then gaster makes deltarune again. I think tobys games are a Paradoxical time loop.
