Ambassador, there is definitely a puzzle at work in the Ruins.

The rules for traveling between there and the Underground are weirdly specific: Only burrowing creatures (like Flowey or the Vegetoids), ghosts (like Napstablook or Gaster), and Toriel can feely travel between the two realms.

Whatever, or whoever, the cause might be, both The Ruins and Underground are experiencing an uptick in monsters "Falling Down" to the point where the monsters now wish they had hospitals.

Certainly Toriel is super-protective. But she's protecting her monsters as much as any visiting humans. She doesn't want either side to hurt the other.

--

While we don't know the exact reasons yet, Sans was once transported to the ruins without his costume, and went through Toriel's care as one of the humans passing through. Which is how he knew who Frisk was and when he's going to arrive in the Underground.

So Toriel didn't recognize Sans immediately, even through Sans knew who she was the whole time.

It does make we wonder if Sans and Papyrus changed costumes when they went back in time to Snowdin though.

---

Do we know for certain that the start of 201X is when the monsters left Home/The Ruins? Remember that Toriel and Asgore recorded a home movie at New Home before Asriel was even born. Alphys found this tape in the Castle, so the Dreemurs had been established at New Home for a while.

So the move to New Home happened before Asriel was born.

Sans and Papyrus would have had to arrive in Snowdin at a time when Snodin was occupied, certainly. But Gaster spent plenty of time in New Home, it's connected directly to The Core.

I don't think we have a solid timeframe on when or why the monsters went back New Home.

-

If Gaster was erased from reality, removing everyone's memories of him.. why would his technology remain? If he had truly been -erased- from the timeline, you'd think everything he made would have been erased too.

Glad we can agree Frisk using his PSI or Determination to power the Empty Gun.

--

Actually the Snails are proven to have souls. Napstablook recalls when Asriel did his 'summoning' and a blazing white light called to him, yet he didn't answer. He remembers seeing all of the snails vanish, absorbed by Flower/Asriel with his monster soul vaccum blast.

---

Why would monsters need a spell to initiate a fight? Most monsters that encounter Frisk start a fight immediately and try to stab him with various things.

Actually essense seems to be something external to the soul. Monster souls vanish on death, but their essense remains behind. Fragments of Chara's soul might have resided in Asriel's essense, but Asriel's mind was able to come back regardless.

-

The idea of the HUD itself evolving is interesting. And I agree that the HUD plays an important role in the game since it changes between Undertale and Deltarune. Although we don't know of the HUD actually did evolve, or it just something woven into the game.

-

Although human SOULs are stated to not be able to use magic, something that still stands in Deltarune, that doesn't mean human SOULs don't have a different power of their own.

Telekinesis is certainly legal for human souls to possess, since we see The Six Souls rebel and rip their way out from inside Omega Flowey, something moving themselves with their own non-magical force.

PSI is a real thing in Undertale.
