Blinking, Frisk found themselves back at that familiar diner and turned to Sans, who was already sitting at the bar like he had been there his whole life. Frisk noted that currently, there was no one else in the diner even though usually it was full of monsters but paid it little mind. Meanwhile, Sans reaches for the ketchup bottle and downs the whole bottle in one gulp before you, he then slams it down on the table and slowly turns to look at you.
*Alright kid. Now I want to you to tell me exactly whats going on here and with any luck, there may be some clue about how to undo all this.
Frisk opens their mouth to speak but Sans quickly cuts them off, a mysterious smile was plastered on his face.
*And Frisk...I need the whole truth. If you are really serious about coming clean...
*About righting your wrongs...
*Then I need to know that I can trust you fully.
*No more secrets. No more games. Thats the only way this will work.
*So let em out kid. I'm all ears.
Sans joked at that last bit, pointing to the part of his skull where his ears would be, but the joke landed on deaf ears. Frisk's calm demeanor slowly dissolved away and was instead replaced with the wave of sins that belonged to them. This was real life. Frisk was responsible for the deaths of countless monsters.
Their past was not a thing Frisk ever liked to talk about, in fact, they had never really opened up to anyone the way Sans was asking Frisk to. But the fact remained that Sans was a good monster at heart. All this time, all he had ever done was for the good of the others underground, especially his brother. So they started slow. Frisk talked about their family on the surface world, the good parts of their life that Frisk had. After all Frisk had all the time in the world to recollect those old days as they had plowed through timeline after timeline. A simpler time that Frisk could only really appreciate now that everything here was so much worse.
But as the story went on, Frisk found themselves choking up more and more. What had once been a crutch to drive Frisk forward now filled the human with guilt and fear. Sans had been right from the very start! Frisk was nothing but a spoiled brat who destroyed everything they touched! People like Frisk didn't deserve to have friends like these. Everything would have been easier if Frisk was never born!
These thoughts plagued Frisk's mind and sent them spiraling out of control, clutching at their head Frisk did everything they could to remain under control. It was then...that Frisk heard a familiar voice.
*What a terrible creature interrogating such a poor, innocent youth...
Every word sent shivers down Frisk's spine as they looked behind them. There at the back of the diner, was Toriel. She wasn't wearing that same motherly expression Frisk had come to known but rather one that seemed distant from this world. Even her words seemed to drip out in a slow lost manner, like they didn't exactly mean what they sounded like. Frisk then looked to Sans, confused as to how Toriel was here, which Sans only replied with a mysterious shrug of the shoulders and a chuckle that echoed through the building and then returning to his third ketchup bottle.
Toriel slowly walked up to the counter, each step making Frisk feel more ashamed. They could tell that Toriel remembered, or at least knew what Frisk had done. Most likely by Sans doing. Frisk couldn't bear to see Toriel like this. No mother should ever look at their child the way Toriel was. But Frisk knew they deserved it.
Toriel sat down on the opposite side of the bar, pausing for a moment to collect herself before speaking, still not looking at Frisk in the eye.
*Sans told me everything. The...genocide of the underground...the resets.
*Even talking about it now is a bit confusing...At first I wouldn't even believe Sans. How could I?
*How could I believe that such a youth like yourself...could ever get wrapped up in something so horrible!
She looks to Sans with an expression of concern. He seemed to be doing everything he could to not be a part of this conversation and Toriel knew in her heart that it was because she had pushed him away after his continued accusations against Frisk. That scene where she pushed him away resurfaced in her mind...
