So...it took me all day to think of ideas, and here goes all my pride. Metta takes reader for a walk of fresh air. Reader's eyes start to turn black with fave colored pupils. Reader gets nervous and Metta is confused. Metta and reader is near the big door to the ruins. Reader pupils grows brighter. Out of their curiosity, they wandered further. They go through the door and wander around the halls. They walk up the stairs and into the ...living room? I don't remember where it leads. Anyway, reader gets a head ache and has a nose bleed and starts to feel dizzy. Reader continues anyway and walks into the kitchen with the aroma of butterscotch pie filling the room. They walk into the kitchen and sees Toriel and freezes. Tori doesn't notice and continues making pie. In skipps a happy young girl, frisk, except frisk isn't so young any more, and a happy young boy, Asriel. Frisk is like the readers little sister. Suddenly frisk looks at reader gasping and catching everyone's attention, and they make eye contact. Reader passes out from such a headache and blood loss, and flash back on their sister/brother relationship with frisk and Asriel. Frisk wanders off, and reader goes after her. Reader is taken in by Toriel, who claims to want to be their new adoptive mother, meets her new brother Asriel, and defeats all obstacle courses and bosses. Sans some how was intact with the vision and told Alphys. Alphys helped reader and the reader woke up. Sans explained what happened because reader was just waking up. Tori, frisk, Asriel, and reader have an emotional reunion and sleep over(all girls). Sans, Metta, and Papyrus stalk the girls for their 'saftey'. I have more ideas but I think that's enough for the next chapter. I don't really think you would like these ideas anyway.
