At the start of this new timeline.
Y/n looks down at his feet before he looks up at his father.
Y/n: Hey father? Can I ask you something?
XGaster looks away from alphys and turns towards Y/n.
XGaster: What is it, my child?
Y/n: So your button allows you to change all of reality. Right?
XGaster: That is correct yes.
Y/n: Can I ask you to use it to give me something?
XGaster:... What?
Y/n quickly raises his hands and waves it off.
Y/n: Nevermind. It's not that important. Sorry for bothering you.
XGaster: No tell me what you want. But I'll only do this for you once.
Y/n looks up at his father before he slowly opens his mouth.
Y/n: So you know how Sanses can teleport?
XGaster: I am aware. After all, I had to look through so much Code to learn how everything worked.
Y/n: Could you possibly give Me that ability?
XGaster: oh yeah, sure.
Y/n: Wait really!?
XGaster: I told you I would let you have one thing. And it isn't some stupid thing like being a harem king. So yeah. This will be easy enough to do for you.
XGaster pulls out the Overwrite button and presses it as y/n suddenly glows a beautiful purple color.
Y/n: Whoa...
XGaster: Enjoy my gift, son.
Y/n: Thank you, father...
Thank you.
Now we see Y/n sitting next to sans as they both sat inside muffets bakery.
Sans: So how's training treating you?
Y/n: While it is quite hard, it's all worth it in the end. How's your pie store going?
Sans: It's going quite well. Papyrus has been a huge help like always. He's probably gonna try and go train with you and Undyne again.
Y/n: He is? Well if he wants to. Undyne and I were thinking of doing some less painful yet still painful training.
Sans: Sweet. I'll go tell paps that he can go training with ya. Seya kiddo.
Y/n: I'm 25 years old. You know what? I don't even care anymore. Later gremlin.
Sans puts up a peace sign and teleports away.
Y/n sighs as he picks up the spider doughnut in front of him and finishes it before he puts some gold into a web and starts walking towards the door.
Y/n: GOODBYE MUFFET!
Buffet: BYE DEARIE! HAVE A NICE DAY! SEE YOU NEXT TIME!
Y/n waves at Muffet before opening the door and bumping into someone.
Y/n: sorry dude-...
Y/n looks down only to see none other than frisk looking up at him.
Frisk: Y/n... Where have you been?
Y/n: Somewhere... Anyway, I have something to do, so I'll see you later bro.
Y/n pushes past Frisk and walks a few feet away before he hears him say something.
