Summary
“Ha!” the laugh is so wrong, it grates on her. “My time is over, miss. And things that happened today… they have shown me how mistaken I was in my thinking, even in my heyday.”
Everyone is losing hope. Even hardy ol’ Gerson. Alphys deflates at that.
“Besides,” he goes on, “There is still someone left – you yourself Dr Alphys.”
“I’m not –”
“Ye’r the last remnant of the royal axis, young lady,” his eyes glint. Her heart aches for Undyne again. “Them good folks downstairs… They’re gonna look up to you. It’s all up to you now, kid.”
After the human leaves a grieving kingdom behind, Alphys is newly elected Queen. Even as she leads the remainder of monsterkind through these difficult times she has no space to mourn for what she lost.
She doesn’t know that an old friend she had thought dead will return to her.

Summary
“Do you hear that Kris?” Noelle’s mother spoke. Kris just stared at the phone, a chill running down their spine. The phone continued to play nothing but garbled sounds.
“...They are pleased.”
“...pleased?” Kris spoke in a broken voice. They were never much of a talker, the idea of it was almost foreign to them, but in this moment, in a moment where gestures and body language couldn’t truly communicate how they felt, their only real option was to speak.
“Yes.” Noelle’s mother spoke once more, her smile widening just a fraction.
“Because now that you’re here… the ritual can truly begin.”
Or:
Author writes a prologue to the events of Deltarune that is almost certainly going to be outdated by canon in the future.

Summary
“G-good point. I’m lucky that I can hide my mistakes.” She peered up at him “You’re a lot braver than me, for sure!” She could only imagine how disheartening it could be to receive more backlash than positivity, it was amazing that he still kept at it despite that.
Clearly, Papyrus didn’t feel the same way if his slumped posture was anything to go by. He avoided her attempt at a cheery smile, looking terribly closed off with his arms tight by his sides and sockets peering down at a rather large crack in the lab tile.
“YES, BRAVE. I’VE HEARD THAT ONE A LOT” He sounded bitter, which was such a foreign note to hear from him that it took Alphys off guard.

Or: Alphys learns that there's more to Papyrus than endless optimisim, and offers a new pillar of support when his usual confidence wavers.
