Sans Au Scenarios

The first meeting

Undertale:
You stepped out of the huge door into a cold winter world, still crying.
When you fell down the mountain and met the first monsters, some completely oblivious Froggits, you have promised yourself to be kind. They deserved to be saved.

You didn't plan on hurting her. Actually, you never wanted to fight her anyway. But in the end, you couldn't prevail it.
You had hit her in defence and didn't think about how much damage you could cause. When she crumpled to dust, you knew it was your fault. If you just had listened to her and stayed with her.
Now it was too late.
You stomped through the snow, thinking of the nice lady full of regret without registering the sound of footsteps behind you. Coming to a halt in front of the bridge you let out a long sigh and mustered the barrier. “Human... Don't you know how to greet a new pal?” You flinched and turned around, nearly slipping up on the snow and stumbling backwards, stick raised high to hit who ever scared you. But the shadow covered person only has one hand extended to greet you. “Don't let me hanging there! Shake my hand!” He sounded demanding jet friendly so you took the hand only to earn a farting noise. You stared disbelieving on your still connected hands while the other laughed shortly. “The whoopee cushion in the hands trick. It's always funny. Anyway, you're human, right? That's hilarious. I'm Sans. Sans the skeleton.” Wait, what? The shadows surrounding him had disappeared and so you were able to see him clearly. You gulped, stumbled a few steps back and nearly screamed loudly. A freaking talking skeleton pranked you.
You have seen many monsters down here already but this was simply to creepy. You turn on your heels and storm off. Leaving a confused Sans behind you. “Well... That was cold.”
Sans wasn't only confused because your reaction. No. He wasn’t expecting you at all. You weren't the usual kid, that used to come back over and over again. Maybe this round would be something new....

Underfell:
When you exited the Ruins you already had killed a couple of really annoying monsters. You weren't exactly font of killing but those who didn't want to be befriended didn’t deserve something else than death.
Flowey followed your trail from the very beginning because he had a somewhat bad feeling about you, but when you spared Toriel he relaxed a bit and started talking to you. “In this place are two skeletons you probably don't want to meet...” You nearly overheard his meek warning. “They will see what they get from annoying me too much.”
You both had reached the barrier by then. “And what would ya do?” Flowey disappeared into the ground and you turn around. And, hell, was he intimidating, towering over you as he was grinning with sharp shark like teeth and one glaring with obe glowing red eye. “You think ya could do anything with that thing? Hilarious.” He points to the stick, clenched in your fists. “Well, it should do its duty.”, you sassed, collecting all your left over bravery. “What ya don't say? A brave one... Anyway, I'm Sans. And actually I'm supposed to capture you, but that's simply not my thing. My brother, however, is a human hunting maniac. Hey! What d'ya think you're doin'?” You had turned your back to him and started to walk away. Not even listening to what he had to say.
