Concept: Gaster creates Papyrus as a killing machine. Also created Sans. Falls into the core, things happen, Frisk feels sorry for him and pulls him back out (somehow).

Papyrus pulls Gaster aside before he can meet anyone else and (re-)introduces himself (“PAPYRUS, HE/HIM PRONOUNS, PLEASE”). Informs Gaster of the current state of affairs- Barrier Broken, Peace with humanity, there is no need for a killing machine, Please leave Sans alone. Informs Gaster that he, Papyrus, won’t be Gaster’s Test Subject any longer. Will no longer be Gaster’s Weapon.

Infuriated, Gaster snarls back, There will be a war with humanity, He will experiment with Sans, Subject Two is a killer, and nothing will ever change that.

Papyrus tells Gaster he can still change. Can still be a good person. Things are different, now. Gaster can be different, now.

Gaster refuses, and re-iterates. There will be a war with humanity, He will experiment with Sans, Subject Two is a killer, and nothing will ever change that.

Papyrus sighs, despondent. Doesn’t look at Gaster. Summons a large amount of magic. Says he will make sure there is no war, best as he is able. Says that he will prevent Gaster from experimenting with Sans.

Admits that Gaster was right about one thing.

The blaster fires.

Papyrus’s LOVE increases.
