the parallels between sans, papyrus, and flowey/asriel are INSANE by the way
by the way, this animation/animatic was made under the assumption that sans does NOT remember resets, and only has knowledge of/is studying them.
both asriel and papyrus are often perceived as a child and look on the positive side of things with a sibling that hides many secrets. both sans and flowey are secretive, have some association with the resets, and are nihilistic in their own ways. someone else could probably do a way better analysis, but i don’t have the brain power right now 😭
some of these scenes are definitely more on the headcanon side. for example, sans meeting flowey in one of the timelines, and then getting stabbed with a vine is just a little bit of my imagination working. it explains a bit of why sans doesn’t exactly like flowey nor trust him, possibly due to having some kinda negative deja vu or getting a bad feeling about him. as a character, i wouldn’t say sans is the trusting type either, so he’d probably follow his instincts. papyrus, on the other hand, would most likely brush it off in hopes of making a new friend. (his loneliness needs to be studied by the way PLEASE 🙏) many parts of the video are supposed to imply that papyrus is stronger/knows more than he lets on, which is more of a theory than headcanon, but it’s there!!
entire idea based on this one post i saw of someone wanting flowey and papyrus to be put under this song because they thought it fit well, and i had an epiphany!!
