This chapter is dedicated to Crunchybanana49 for being an amazing person. Also if you like Bakugou x Kirishima from my hero academia I recommend their book colored strings. It's sooo good.
Bill's Pov
"Your welcome, also Sixer your a freaking jerk!" My little sis, Skylar shouts.
We laugh as she yelled that, which made her smile, man have I missed my siblings.
Sixer growls and walks out, slamming the door behind him.
"So...want to introduce us Bill?" Llama asked sarcastically.
"Oh, right! Pinetree, Llama, Fez this is my little sis, Skylar. Skylar this is Pinetree-"
"Dipper." He said.
I pouted and left the room, while Sky mumbled something to the others making them laugh. I sat on the floor watching ducktective. I started dozing off until someone sat on my lap.
"Bill, are you awake?"
I open my eyes to see Pinetree's worried face. Guess I must have actually fallen asleep. I hum and hold him closer, burying my neck in his as he plays with hair.
"Finally the idiot sleeps." Skylar said, I'd recognize my own little sisters voice anywhere.
I was to tired to open my eyes and glare at her, heck I couldn't even lift my head, so I decided to growl at her.
"Well F you too, Bill." Sky said.
"Bill, calm down and go to sleep." Pinetree whispered, as I felt his hot breath on my ear.
I stop growling and start to enter the dreamworld.
Skylar's POV
I sigh and sit next to my brother and his mate. It's ridiculous how they don't know they're mates and yet they act like one.
Let me explain, demons like me and my brothers have mates, a person who is bound to you for life and if they die they are reborn into a life, if they are mortal. One way you can tell who someone's mate is if the person is usually angry, like Bill and Kill, they can instantly become calm around their mate or when their mate gives them a simple touch. Another way is if they are really possessives over them, they will hurt anyone who makes you cry, injures you, insults you, or anything of the sort. When you are hurt they take care of you, and bring you your favorite things and will watch anything you want to just to make you feel better, they snuggle with you and make you feel at ease. They try to never leave your side, as well.
My thoughts drifted from my older brother and his mate to my mate. All of our happy times together, when he took me to the beach after my bully kicked me. When he proposed, when we found out we would have a kid, our first date, our wedding, our honeymoon, almost every day was amazing, except when I had a miscarriage.
I am brought out of memory lane when something wet land on my hand. I lift my hands to my cheeks and realize.....I'm crying. I normally never cry except when I had the miscarriage and the day it happened.
"Are you Alright, Skylar?"
I look over at Dipper, who looks at me worriedly.
I nod and give a small smile. I look over at Bill and see him sleeping peacefully. He hasn't slept since Dipper's last life, which was a 2 decades ago.
"Hey Dip, Ima go for a walk." I said to him.
He nods his head and goes back to playing with Bill's hair.
I smile and get up, I pop my back and head out the door, and head into the woods.
All these murders, the last time something like this happened was in Dipper's last life. Poor thing would stay up well into the night with Bill trying to solve the mystery, I would try and help from occasions, but I had my own life with my mate. You could never see Bill or Dipper apart and when you did it would be for the holidays or an anniversary gift. They were together for 10 years before Dipper was assassinated.

It's a bit of a filler but it's also going into Skylar, Dipper's, and Bill's past. This has been the 3rd longest chapter. Anyways Gravity Falls does not belong to me. Here is what Skylar looks like;

Anyways hope you enjoyed and Buenos Noches or Buenos Dias.
