(Frisk pov)
I could hear mom from the top of the stairs. She was talking through the door again. I was used to this. I had learned a few years ago she did this. The voice from the other side was harder to hear but sounded male. I used to joke to myself it was mom's boyfriend but all they ever did was tell dumb pun jokes back and forth. Tonight that wasn't the case. The male voice had tried to make a few jokes but mom didnt laugh o make jokes bak as she usually did. Then I heard her speak. Her tone serious.
"I'm sorry friend. I cannot joke tonight. I... have something to ask of you though. Please... make me a promise. Promise me that should a human ever come through this door you will protect them. Please..." I could hear the tears in her voice. I was upset knowing she was speaking of me. I had lived with Toriel for 10 years now. I was told by her that it was dangerous to leave the ruins but she could teach me and so I stayed. I did not have much in the human world after all so I had no desire to go back. I soon took to calling her mom and learned magic. Then a few days ago she said I could leave the ruins and meet others who could teach me more. I was excited and knew I could always come back to her but... did she trust me so little as to ask this person she had never met to look after me?
"Uh... sorry lady. I like your jokes and all but I don't really care to make promises. Then again I don't usually talk to locked doors either... Okay, I promise," the male voice told her. It was strange though. The voice always had sounded so jolly and full of life but when he spoke those words he sounded cold. I felt myself shiver. Somewhere in the back of my mind I felt I had heard that voice before but could not remember where.
"Thank you..." my mom told him the sound of tears still there but now with a smile. I sighed and went back to my room.
My room was nothing special. It had pictured me and mom had made along with a few awards mom had gven me over the years. I felt the tears in my eyes but quickly wiped them away. I had wanted to see the other side of the door and meet other monsters. I had hoped to do so with mom but after a few years I knew that would not happen either. I was my own person now and ould have to fend for myself. All the thoughts of what the world beyond the ruins door and other monsters and their magic flooded my mind as I layed down. The last thing I thought of was who this guy would be that mom had asked to protect me.
The next day I entered the puzzle code to open the door. Mom watched was I walked through. I didnt look back at her though. I couldn't without starting to cry again. She had held me yesterday and baked me a butterscotch cinnamon pie ask a gift. Today though was a new beginning. I stepped through the doorway and into a snow cover forest. It was dark and hardly any sounds could be heard. I heard the door close behind me and closed my eyes tight to not cry as I ran forward. It hurt too much to just walk but suddenly I was stopped. I feel having hit a rather solid object.
"Well that isn't how people usually greet new friends but maybe we just do things different here," I heard the voice that had come through the door chuckle. I looked up to see a skeleton in a blue jacket and white shirt with black shorts and house slippers. He had a wide grin on his face. I blushed and looked away before getting up. He was only slightly taller than me and I was short. I knew mom was about normal height for monsters so this guy was rather short too though with monsters you could never tell an age so who knew if he was still a kid.
'No, kids wear stripes. That is why everything you had till you were 18 had stripes... so he must be grown.' I told myself.
"Can't talk either? No wonder she came to make jokes with me all the time." The skeleton continued. I glared at him.
"I can too talk I just want a decent conversation if I do. Not dumb jokes like you and mom tell!" I was not sure why he made me so angry but my head started hurting and my vision went red for a second. In the second after I thought I saw one of the lights that seemed to be his eyes turn a vibrant blue. When I linked it was gone however. He just grinned at me. It seemed like all he could do was grin though.
"Good to know. I thought this was going to be a bonely conversation," He looked at me as he said this and I could hide my smile. Mom had used that type of joke before as well. He couldn't be so bad. I hold out my hand to him.
"Well bonely guy my name is Frisk Dreemurr. Nice to finally meet the voice behind the door. Hope I didn't ruin your day." I make a joke back. I wasn't very good at them. He smiled bigger and took my hand and suddenly there was a loud fart sond. my eyes widened as I looked at his hand that had a miniature whoopee cushion. I busted out laughing. For a second he looked surprised at this but then just smiled back.
"Nice to meet you Frisk. I'm Sans. Sans Skeleton. Yea I suppose I talked to your mom a lot through that door. Didn't know she had a kid really. Didn't know you would
be so..." He seemed to stop himself as if thinking of how he wanted to word his sentence. 'Maybe there is more to him than those dumb jokes after all.' I think to myself as the lights in his eyes seem to vanish as though he closed his eyes in though.
"I'm not a kid. I just turned 20 in fact," I told him defiantly. He just grinned more and I sighed. Monsters stopped counting years after a time since they had very long lives. I still couldn't tell how old he was from talking to him. He acted so childish but at the same time he was obviously hiding something.
Not knowing what to say we walked on in silence. From time to time I would see a sign pointing the way to Snowdin. I assumed that is where we were headed until Sans suddenly made a turn to an unmarked path. I followed still now sure what to do on my own in this new opened land. We walked past openings in the wall showing glowing eyes peering down at us. Soon we entered a cavern filled with small glowing lights. It was dark and hard for me to see. Sans had his back to me.
"Um... where are we? It is kind of hard to see here," I chuckled feeling nervous. When I was younger and just started living with mom I had memories of a place like this. It was a dark place but I was sure the dream had been a dark hallway. I remember a figure of some kind at the end of the hallway They had a glowing blue eye.
That blue eye like I though Sans had earlier. With that thought I felt my head start to throb and I winced.
Sans turned to me at the sound looking happy at my pain for a moment before I saw the lights in his eye sockets vanish again and he shook his head and came over to me.
"What's wrong kiddo?' He asked softly. He put his hand on my back and the feel brought back more memories. Sitting in a warm house with him and another skeleton I didn't recognize. There was a huge plate of spaghetti sitting at the table. For some reason I felt numb though. I was not sure why. I should have been happy. The two skeletons had large grins but I couldn't return the smile.
As the images raced through my mind I screamed and fell to my knees before the world went dark around me. The last image I saw was Sans reaching out to catch me.
