I Was Reborn In MafiaFell as an Oc?

Chapter 1

((It's MafiaFell, do I even need to say it? ... Trigger warnings galore, and reader discretion advised...))

Death, one of life's greatest mysterious, what happens after your die? Are you gone, go to heaven or hell? Or are you reincarnated, well for certain people Reincarnation seemed to be the answer. Much like Alex, they were bored with life, or more so, they were done with it. Their life was one bad thing after another, so it didn't matter to them when they were hit by a out of control truck. But what DID matter, was waking up as a baby in the freezing snow in a basket. Though they didn't have to wait in the snow for long, as a .... skeleton with sharp fangs brought them inside their large and fancy house. The skeleton was weird, they kind of looked like a Fell Papyrus. But in a nice 3 piece suit, and young, barely a child even. 

???: "Dada, Sans, I founa baby bones on the stairs! Can we keep em!?"

That proved it, this was a Fell AU of some kind, which one, Alex was unsure. 

Gaster: "A baby Bones? Impossible, if there were other skeletons I'd know about them."

Looking into the basket Gaster was shocked to see that there was indeed a baby bones in the basket. They were... the first skeleton Gaster had seen other then his boys in a long time. But who left them here, and why? Looking them over they had vertical scars across their eye sockets and more on their arms, legs and ribs. Sights of abuse maybe? The scaring on their limbs seemed healable with magic. But the ones on their ribs and eye sockets weren't, who ever did this was dead if Gaster found them. If they weren't already, something as precious as a baby skeleton is ... Hmm Sans is to old, but Papyrus... They were young enough to be this one's mate in the future. Perhaps the skeleton species wasn't as extinct as Gaster had thought before. And the way the baby was looking around, like they were planning or surveying the place. They were going to be very useful, very useful indeed. But they'd need protecting, can't have Papyrus' future mate killed off before they could procreate. 

Gaster: "Well then, I think we will keep them. They can be very useful in the future."

Papyrus: "So I get a new sibling?" 

Gaster: "No nothing like that, more like a friend that lives with you."

Sans: "What you're serious? You're gonna raise a baby?"

Gaster: "I've done it before."

Sans: "Yea and we are exactly a normal family."

Gaster: "Oh Hush~! Now all we need is a name."

Alex's POV:

It's been a good while sense I was reborn, Gaster has been trying to get me and Papyrus together for years now. And shocking it, was a slow burn plan, Gaster was smart and manipulative. But I saw though it, didn't stop it from working. But I saw through it, Papyrus is 16 and I'm currently 14. I kinda stopped growing, so I'm only about 4 feet to Papyrus' nearly 8 to 10 feet tall. And his shoulder are so broad I can ride on one of them. Which I do constantly, cause it's "safer" according to Gaster. Not that I can't hold my own or anything, "Safer for everyone else." He says, I mean... am I that chaotic?
