chapter 18

(Frisk pov)

Ever since my big sister Y/n got away from the experiment institution I have been very worried about her and went to check on her to see if she was ok in her room . when I got to her room I knocked first to see if she answer but no reply, i knocked again ...... still no reply so i opened her door to see that she is gone. I was panicking out of my mind of what happened to my sis till i noticed that the window was open. i went close to the window to see a trail of blood and I know it was my sisters blood thanks to my abusive parents and the experiment institution. I look to see where the blood lead to and what i saw it was going towards mount ebott. whelp looks like sis is in the underground but the question is how long has she been gone for cause my abusive family said that she been going out hunting so i just left sis alone for a long time. Now i know that my abusive parents where lying so now im going to go get ready and find my sister to see if she is ok. I went to go pack my things so i can also get away from the abusive family as well but got to wait till they go to sleep cuz they are still drinking like the idiots they are.

( alil time skip to were they are in there damn slumber)

Now that my parents are asleep i can climb out the window and get away from this hell hole of a home. It took me a few hours to climb the mountain. i made it to where the hole to the underground was and jumped right into the big hole. I landed in the golden flowers again and heard my sisters voice. i was surprised to see sans there with my sister holding her as if his life depended on it or not but by the looks of it he is being over protective of my sister. It took my sister to calm him down and for me to promise not to reset or hurt anybody in this timeline. when i remeber the timelines i did and regreted for what i did to them even to my sister she had to go through hell alot of times because of me. i know she forgives me but i want to make it up to her for the resets that I did and it was chara fault too. speaking of chara where did they go anyway oh well ill find out later. I was also wondering who is this W.D gaster person is at the moment cause i never heard of him in any timelines. i was also wondering why sans is with my sister and not his brother this time i guess im going to ask sans himself if he let me talk to him at least.

(sans pov)

when Y/n teleported to the entrance to the underground I was worried about her getting hurt by another human. I teleported after her to see that the one that fell down was none other than frisk that fell down to the underground again. I was still mad at frisk for what they have done but what makes things alil complicated was that frisk was Y/n sibling. welp it cant be helped that frisk is Y/n sibling but they have to make up for what they had done in the other resets. frisk probably has alot of questions on why im here in the ruins. I was very surprised that Y/n knew about the timelines but when she said that she could see the past, present, future and read minds I believed her but I don't think she is telling the truth cause of frisk is right there but why ? would she tell me if the kiddo wasn't here. well ill find out later when she fully trusts me.

( your pov)

I know that sans doesn't trust my lil brother frisk for what he did to his brother and friends in the past timelines. I also know that sans wont stop being curious about why my eyes change into different colors but ill tell him that when im ready to tell him.

Y/n- so frisk how was the upper world

Frisk - its still the same I guess

Y/n- .. hmmmm is that so lil bro. whelp do ya have any questions lil bro and sans what questions do ya have to ask as well.

Sans - I know there is another reason that u take on walks but I wont push it for now.

frisk - what sans you have a dad

Sans - yep I have a dad but he was stuck in the void but still tryin to figure out on how he got out of there in the first place.
