Chapter 17: Safety has a cost

I woke up to the smell of eggs. I got up from the couch with half led eyes.

PAPYRUS : GOOD MORNING HUMAN!!!

Y/n: Good morning papyrus...

I looked around, not seeing Sans.

Y/n: Where is Sa-

I felt a tap on my shoulder. I quickly turned around to see Sans with his signature lazy smile.

Sans: Heyya kiddo.

Y/n: Heyya....

Timeskip Because breakfast is...:

After eating, I told PAPYRUS I need to talk to Sans in private. Paps left the room.

Sans: Is it about what might happen?

Y/n: Yeah....should...should papyrus come?

Sans: .... I'm not sure...because...that's one thing I didn't tell you. Sometime, timelines are spoiled by what I call genociders.

Y/n: Timeline...you mean like...the possible events?

Sans: Yeah, each world has a timeline from which multiple outcomes are happening.

Y/n: I see.... But that human that fell down... I'm sure there's nothing to worry about...

Sans: But still.... I don't wanna lose him again...

Y/n: Again?

Sans: I'll...I'll explain it later, for now, let's go.

Y/n: So, is Paps coming?

Sans: ..... Papyrus!

He opened the door and quickly sat with us.

PAPYRUS : YES SANS???

Sans: Do you....

He sighed.

Sans: Do you wanna meet an old friend of mine?

PAPYRUS: YEAH!!!

Sans: Hehehe.....

I saw a hint of sadness but it quickly vanished.

Sans: Let's go then.

Y/n: Yes.

We went outside and started to walk out of Snowdin.

Timeskip to the big door:

We arrived in front of the door, it was slightly opened.

PAPYRUS : OH, LOOK, IT'S OPENED, MAYBE SHE HEARD US COMING!!!

I quickly took a glance at sans as I could see dread on his face. He saw me watching him as his lazy smile was back.
I opened the door completely to see that the long corridor was empty.

Y/n: ....Weird....

Sans: Hey kiddo....

I looked at him as he again had dread on his face.

Sans: Be ready, something bad might happen....

Y/n: ...... Ok....

I looked back at the empty corridor. I went in and started to walk. Except the sound of our foot steps, there wasn't a sound.

Y/n: Toriel? Are you there?

I continued to walk but stopped, feeling something weird.
They both stoped to walk and looked at me.

Sans: What is it?

I looked down and saw a lot of dust.

Y/n: Why is there so much dust....
