I know you said this isn't TMFF from San's perspective... But have you thought about writing The First Step from his perspective? I really want to know what he's thinking cause it's such a beautiful scene.

Too. Many. Feels...

Omg awesome chapter

Woah... did he just kill Gaster? Mercifully-ish? Boom. Mind-blown. Was not expecting that.
...

Thank you for writing and posting this!

Awwwwwww

The seventh human? Isn't Frisk the eighth?

I think you repeated a bit in the second and third to last paragraphs.

He could have at least told Alphys that Frisk promised not to reset.

I liked the 'three pilots' idea for Comic Papyrus you used. One new personality influenced heavily by two old ones. It's a really interesting concept.
I also liked that part about a bridge.

Sans, you're going to take this forgiveness even if I have to cram it down your nonexistent throat!

Aaaaaaa no more cursing Sans, no more sadness sansess, idk. I'm somehow sad and somehow happy that it now ends here with this part. I'm happy that Sans could toss out all of this science stuff and trade it so... Nyeh, other science stuff. But it's better. Stargazing is nice. No Gaster there. I hope.

It was a great fanfic, I loved your interpretation of Sans!

Im glad the long ass reviews don't bother you. I feel almost guilty for commenting almost every chapter of your fics, but it's just what I learned to do, idk. I like commenting, even if it has nothing much to say or it won't give you anything bc you are already over with this.
But I hope you continue writing Undertale (& MM) fics bc that was clearly awesome! There are a few things I still don't get (as I said, why did Chara leave, they wanted to destroy everything) (or that unrealistic realistic sciene speak I couldn't get), but I loved it anyway, it was an epic thing. I don't know if there are any other Undertale fanfics nearly as good as yours out there, but I can't imagine that. Can't wait for the next fan fictions. And thanks to you I somehow feel now like shipping Frisk and Sans somehow (the last chapters weren't much shippable tho).

I don't think this is the right time to think about him, but what's about the river man? I think he warns Frisk saying "Beware of the man who speaks with his hands" or something like that. Does the river guy know about Gaster? I as always wondering.
Concerning your fan fiction I would like to know where the river guy is now. Is he still in the Underground, traveling between the areas? Or did he moved on the surface?
What's about that hidden dungeon, only avaible when successfully doged all names of kickstarters etc in the credits? And outside that cave, on the left, on the background, is an house. Did you plan to add something to those things? I know, there are many fanfics of yours I still need to read, but I can't stop myself in forming those questions.

Back to the fic, are these Sans-es from other dimensions or universes? Even human Sans-es? But why so many?
So, why not sacrifice Frisk. I'm glad Sans refused, it sounded so tempting for Sans, especially when you think about what Sans had to live through thanks to Frisk. I'm so glad...

Ah, so they didn't leave Waterfall, but there was in fact a door. Not in the exact same spot as in game, but in Waterfall. That was a bit bard to understand in TMFF, I didnt realize that that was only a flashback and Frisk was in fact still in Waterfall.

Btw, I have to say, I love some of the things you invented for this story, for example the fusion thing or bow humans could learn magic.

God, this hurts so much, and nothing is okay. I don't know how that should be ever be okay again. Maybe if Sans would lose their memories, and maybe everyone else too.
