I’ve gone into why Gaster must be a human in the script:

A Gaster follower is holding his talking human head.

The Riverperson warns us to “Beware the man who speaks in hands” and “Beware the man from the other world.” The First is definitely a reference to Gaster.

Sans mentioned he had company when “we” went to investigate the timeline anomaly on another world. Sans and his friend are both from another world, one where anime technology is real, which is how Gaster was able to give the monsters a tech level that exceeded even the humans on the surface above. And Sans wasn’t the one who built The Silver Key Machine behind his house, because he can’t fix it himself.

Sans isn’t the one from another world we need to beware. His “friend” Gaster is.

Also, just to recap, Asgore’s calendar, which the narrator calls old, says Chara arrived at New Home at The End Of 201X. Which would be in winter. We see no flowers when Chara falls in Undertake’s intro, backing this up. And Chara’s plan required buttercups to poison herself, and Asriel tracked golden flower seeds back to the Underground with him.

So Chara and Asriel’s doomed buttercup adventure happened, at the very earliest, in Spring 2020.

After the memorial fountain was built in 201X.
