Hey guys! I came up with the idea for this one a while ago. I'm currently on a hiatus (stupid school), so I don't know when chapter two will be up, but it will eventually be up. This contains Mabel/Bill, Wendy/Dipper, and hints of Gideon/Pacifica though it's not an official ship for the story. Oh, and the OC's are the children of the canon characters, and they play a pretty big part, but I like to think they're sort of well-written. I don't own Gravity Falls, the amazing Alex Hirsch does.

The instant Bill Cipher opened the door, he knew something was wrong. How couldn't he? After all, his five-year-old daughter alone came out to meet him. No Mabel or week-old son to be seen.

Probably just sleeping, he thought to himself as he lifted the kindergartner in the air.

"I dressed myself today." Charity Cipher announced, puffing out her chest to show off her yellow princess dress . . . which was on backwards, a mistake her mother would surely have fixed.

"Excellent job, my little Ghost." The demon replied affectionately, trying not to let his worry show. "Where are your mom and William?"

"I haven't seen Mommy all day. William's sleeping." Charity responded, starting to suck on her thumb as her dad set her down.

"When did you wake up?" He glanced worriedly at the clock. Four o'clock in the afternoon.

"Six-one-eight." She replied.

"You were up early today." Bill said, trying to swallow his panic as he speedwalked over to little William's room.

"Yup!" She crowed, grabbing the back of Bill's shirt and walking along behind.

Bill leaned over and lifted his son. Phew. Still breathing. He cradled the newborn in one arm, heading to the kitchen to get some emergency breast milk Mabel always put in the kitchen just in case. She would never allow her baby to drink formula if she could help it.

"Charity, can you get my phone and bring it back? It's in the pocket of my suit jacket." Charity sped off, and as Bill was heating the milk with some of his blue flames she handed him the yellow-cased smart phone. He found the right contact and selected it, holding the phone to his ear with his shoulder.

"Hello?" Greeted the voice of a twelve-year-old girl on the other end.

"Katie? Can I talk to Dipper for a moment?"

"Oh, hey Uncle Bill. Yeah, just a second."

His ear was assaulted by Katie hollering loudly for her stepfather, loud footsteps, and muffled scolding before the man he needed was on the other end.

"Hello?"

"Pine Tree, have you heard from Shooting Star today?"

Dipper had obviously heard the worried tone of Bill's voice. "Her phone tried to call me at about three in the morning, but I figured it was just sleep dialing cause she fell asleep texting Candy last night. Why? Is she okay?"

Now Bill was panicked. Not even his wife's twin brother had heard from her. "I don't know. I came home about twenty minutes ago to find Charity and William alone. Char says she woke up at six eighteen this morning and nobody was home."

Fear was now audible in the younger man's voice. "She would never leave the kids alone. When did you last see her?"

"One-thirty this morning when I left the house to make a deal with Bud Gleeful to help his wife get over her trauma."

Shuffling sounds from the phone. By now Charity was staring at her father with wide eyes, having finally figured out that something was wrong. Even William had stopped sucking on the bottle.

"Call the police. I'm on my way with Stan and Wendy."

"So let me get this straight. Mrs. Cipher was last seen at one-thirty and most likely disappeared between three and six-eighteen. Her jacket was left behind, but her seashell necklace, wedding ring, and shooting star sweater are missing. Tell me, how old is she?" Blubbs had been replaced, and the new sheriff sat in a large chair. Mabel's chair. Honestly, the young man was grating on Bill's nerves.

"Twenty-five years and three months exactly." Bill replied.

"How old was she when you married?"

"Nineteen years and sixteen days."

"How old are your children?"

"Charity is five years, four months, and seventeen days. William is seven days."

"Sounds to me like she just got tired of her young life being held down and up and left." He pushed his glasses farther up his nose.

"That doesn't sound anything like her!" The four adults of the room bellowed in chorus.

"Mabel is my twin sister, and she's known all her friends here for thirteen years. She adores Bill and the kids and would never do anything drastic without talking to me, Stan, Soos, Candy, Wendy, or Grenda about it first."

"Not to mention the kid's a lousy liar." Added Stan in a gruff voice.

"Mommy loves me!" Charity, sandwiched between her father and uncle, announced defiantly with crossed arms.

The new sheriff seemed surprised he'd been contradicted. He rose and crossed the room, turning at the oak door to say one last thing.
"Well, you're all free to look for Mrs. Cipher, but I'm not wasting time and money on an estranged runaway adult." And with that he exited the small cabin, slamming the door behind him.

"I can't believe he just . . ." Dipper's voice trailed off when he noticed Bill's stony expression. He stared at the demon worriedly. "Bill...?"

With a scowl, he stood quickly. "Call everyone fortunate enough to call Mabel Pines-Cipher a friend. We will find her if it sends us to our graves."
