It's the end.
Frisk could feel it; their friend's souls were in there somewhere, weren't they? Asriel was doing a good job of keeping them out of the human's reach, close yet not close enough, but they were determined to reach out to the lost souls.
"Toriel, Asgore, Papyrus, Sans, Undyne, Alphys…c'mon…please…" Frisk's cries for the monsters were reduced to mere whispers, as if a strong current of wind was facing against them.
Finally, they appeared.
Faces blurred, bodies suspended in midair, motionless…Creatures that were once alive and full of expression now echoed the same words over and over again.
Frisk could now slightly move, they could approach the lost souls, and almost feel their pain. The words they spoke caused the human a headache, one that felt more sorrowful than anything else.
As Frisk began to pick some of the phrases out, the reality of the situation began to set in. "Please save…don't worry about…surely there must be someone you'd rather…"
This whole time, the human had been able to help everyone, hear them out, and become every monster's friend. Frisk never would've guessed that they'd be thrown into a scenario like this one.
Only one could be saved, and Frisk had to decide between all of their new friends.
Asriel's laughter could be heard as this realization came to the human child, but they calmed down and planned to patiently listen to every statement.
But no-Frisk already knew who they wanted to save—they'd made a promise to see her again from the very beginning.
The child turned to the soul and held out a hand, waiting for something—anything—any reaction at all, before calling her name. The name of the one who had cared from the moment they fell.
"Toriel!"
But instead of getting a response from the soul, Frisk fell into a memory that was not their own.
A blinding flash of white briefly took away the child's consciousness, drowning out any reaction Asriel might've had to Frisk quickly deciding whom they wanted to save.
An image of Toriel's house slowly came into view, but it wasn't as decorated. Bookcases were empty, the vases didn't have any plants in them, and the extra rooms were completely blank. Frisk was placed standing at the staircase that led towards the exit of the ruins, they looked around—confused for a moment—before following their urge to walk down the steps.
Faint sobs could be heard from the ending of the hallway, Frisk walked slowly, before realizing they couldn't hear their own footsteps. In fact, it didn't seem like the human could do anything besides watch and listen to what was happening in this scene.
And somehow sense the pain in the atmosphere, there was so, so much of it.
When the door to the ruins came into view, Toriel could be seen sitting in front of it, sobbing. She held some of her possessions, a few books and images, as well as some seed packets, but set them down while she was crying.
Then Frisk realized; this must've been what happened right after Toriel left Asgore.
