Me:Okay By the Way,I will be using a Narrative Point of View(Telling it by no ones p.o.v in the story) for this last chapter!
--------------------------------------------------------------

      *1 Week Later (Narrative's P.o.v)

       Mabel lay in his pink bed, yawning tiredly. She gets up and walks over to the bathroom. She puts on a pink sweater with a smile face on it, complete with a yellow skirt. She sighs and combs her hair slowly.

She looked into the mirror and just stared at it sadly. She walked out of the bathroom and put on a smile. She walked,opened the Pines door. The sad thing was,on the back on her smile sweater,a frowning face was on the back,covered by her hair.

"Hey,Dip! Can Can! Your here!" Mabel exclaimed happily, all fake.
 
"Yes I am. Decided to come so me and Dipper can go to the pool later on. Me and Dipper have finally made up because of the fair. You know then after..*ahem* um.." Candy goes quiet.

Dipper tenses. Mabel stood there,then frowned.

"YES. I. Know. Hehe.." Mabel called, laughing softly. She turns around and stormed back into the Shack, her eyes tearing up. Once, she got in, she collapsed on the floor and sobbed her heart out. Tears streamed onto the floor. Grunkle Stan and Ford were out to get things at the town, so it was just Mabel alone.

Will decided to stick around Gravity Falls because it needs a new demon to run around here in the way it needs to be. He wasn't in a hurry to go back to Reverse Falls.

      
"B...B..Bill..." Mabel whispered.

He went in a ball and put her head down. She looked up and marched up the stairs. Dipper and Candy walk in, look at each other, concerned. Mabel decided to do something better than cry and wait. She grabs some thread and yarn.

Stitching, and sowing, she finally takes a look at her finishes masterpiece, 1 hour later. A stuffed toy with looked like a yellow triangle. With a little black bow and a dope top hat. She smiles and hugs it tightly. She smiles sadly and puts the toy in her bed. She lays next to it and stares at the eye. She giggled.

"You'll be back, right? Of course, you will. You always do." She called happily and ran around with the toy.

She ran down the stairs.

"You guys can go without me! I'm staying, as I'm expecting someone~" Mabel sung.

Candy grabs Dipper and they both run outside. She wanted him to be with her again, but some things weren't ever coming back.

     *2 Weeks Later (Dipper's P.o.v)

I move the camera up so that it was facing me. I frown deeply as I grab it and sigh heavily.

"Okay. Now, I've got a problem. Big problem. This is beyond my control and I want to help. My sister..Mabel went through stages of grief lately. Your probably wondering,"What?! The Mabel Pines,the most upbeat, happy-go-lucky girl in Gravity Falls is Sad?!" Well, she has been through something no one would understand. So,I will begin the day to cheer her up,and help her if she needs it." I explained nervously.

The front door closed and outside was Mabel. She had knotted hair and just sat there, crying. I grab the camera, as it wobbled down.

I finally opened the door and ran to Mabel, panting.

"Dipper please leave me alone. I'm waiting." she whimpered. 

"No Mabel. I want to help you and I will." I stated seriously.

I sat right by her. She looked at me,sadly. I begin to start my plan of action.

        *5 hours later (Dippers P.o.v)

       "TAH DA!" I yell, throwing her favorite sparkles in the air.

She still wasn't amused. She looked so sad and depressed. I start to walk away sadly,then trip over my own shoelace, causing me to fall backward into the mud. The glitter I had popped and sprayed me in pink glitter. I cough, my foot in the air and the other was stuck on the floor. Mabel turned to be and sputtered, covering her mouth.

She giggles, then start laughing hard, holding her stomach. I laugh slowly.

"PFFFF Dip! Hahahaha! What happened?! Hahaha!" She yelled happily, pulling me up. I was a complete mess.

"Well..I tripped..Mabel, Hey, I know you've been through so much so.." I start, slowly pulling out the narwhal.

                     (Mabel's P.o.v)

       Dipper pulls out a stuffed narwhal that I recognized from the fair. I gasp and tear up.

"You found it." I stated sadly.

I smile at the toy, and chuckle. Dipper nods.

"Mabel,You know he's never coming back, right?" Dipper asked me.

I go wide eyed in fear, and sigh.

"If I believe..*stuttered* h h he w w will.." I say hopefully.

Dipper looks away, and back at me.

"Your scared of moving on. And who could blame you? I'm scared too. But,you have to move on, Mabel. I don't know what's going to happen, but whatever it is, but you don't have to fear because we will do it together!" Dipper called sincerely.

I nod, tearing up. Dipper opens his arms,and smiles.

"I think you need a awkward sibling hug. Maybe it's twin sp or something, but I just know you do right now." Dipper states, motioning.

I run to him and sob as I hug him too.

"Dipper!...I s should've listened to y you! Boys..they-" I start.

Dipper interrupts quickly.
      
"Hey, Boys are jerks. I get that, but that guy, he cared about you. I saw something in you both. You were so happy, since your boy fails. He gave you a way to live. A way of life, Mabes. This will sound very sappy, but He will always be-" Dipper starts and points to my heart softly. "In here." Dipper concluded.

I giggle softly. "Whatever Dipstick. You are not a jerk like others too. Don't forget that." I say happily, playfully punching him.

He rubs his arm and chuckles. "Alright. What do you want to do?" Dipper asked happily, standing up,and extending his hand. I grab it and stand with him. "I'm in the mood for a-" I start.

"WATER BALLOON FIGHT!" Stan stated with a grin.

Stan runs out, holding a water balloon. He throws it at me, getting me wet. Ford holds a bucket of water balloons, holding one up.

"Stan! Our neice and nephew don't have water balloons!" Ford exclaimed.

Dipper smirks and stands up. I grin big as we play the biggest game of water balloon fight.

Eventually, We all got soaked, and I'm not exaggerating, we were SOAKED. We then decided to make some delicious chocolate chip cookies, or try to at least.

      *1 month later (Narrative P.o.v)

"Dipping Sauce! Hurry up,ya nerd!" Mabel yelled outside,her hair in a pony tail.

She brushed her sweater happily. Mabel jumped happily. She was so excited for her time at the pond, the Pines next Mystery hunt, as her face expressed it.

Dipper went out with Mabel. He had his book in hand and smiled lightly. Dipper held it up.

"This will tell us exactly where the pond should be. If I calculated precisely...hm" Dipper murmured, biting his pen in irritatation.

Mabel giggles and looks over at the opened map Dipper had gound in the book.

"AH HA!" He yelled, startling Mabel.

"You found it?!" She questioned.

"Well, we didn't find it. We are still here..but I think I know where it is!" Dipper exclaimed with promise.

I woop in the air and punch my hand into the sky. "MYSTERY TWINS STILL GOT IT." She yelled loudly.

"That's my Dip! Right there! Dippy Dip Dot in da houseee! Woop WOOP!" She screamed happily.

Dipper laughs awkwardly. "Yeah..You know, we should do it tomorrow. Save it for our last day tomorrow,you know?" Dipper sadly countered.

She sighs. "But, I want to stay longer here! I'm not waiting another summer! Why can't we stay longer?" Mabel pouted.

He nods in agreement.

"But, why? If your stilling looking for him-" Dipper starts sadly.

Mabel stuttered. "What!? Dip, he's gone. I get it now." She replied.

He smiles. "That's good.. Hey, you want to play one more round of Mini Golf?" Dipper asked.

"Yes sure. But, let me get a breather." She stated.

He walks up the tiny stairs and opens the front Mystery Shack doors.
      
She screamed happily and spins.

"Bill, I am SO close to finding you. I mean..I just feel it! Deep Deep down!" She whispered loudly.

Then, she sighs regretfully. "But, What if you..are really dead?..Is Dipper right?.." Mabel mumbled, looking out into the woods.

"We'll..meet again..don't know where..don't know when! But-" She starts happily, perking up.

Her brown hair blows in the wind with pleasure.

"I KNOW we'll meet again,some Sunny Day!!!!" Mabel called with joy.

"And I believe you'll be back...some sunny..day.." Mabel called.

She tears with joy, and starts to walk inside.

 "My persistent Shooting Star." The figure said happily.

The figure was floating with his little back hands and yellow color. He started to come out of the bush, but stopped halfway. He sees Mabel humming happily, and Dipper opens the door for her. Those two laughed happily. The figure tenses and backs up. He sadly turns away.

"It's for your own good. You're dead to her. And you will be forever." Another figure called.

The figure puts his hand on his shoulder. The first figure pulls away.

"She didn't know. I know she didnt-" The first figure started. The second figure frowned.

"The dagger didn't kill you,did it?" The second figure questioned.

The first figure tears up, with his back turned away.

"Bill,demons can't love. Doing so would kill them. And,you fell in love, and died. That's why much demons don't get attached. You're lucky I can bring you back with dark magic." The second figure stated darkly.

The first figure, Bill, stood in front of the second figure.

"How do you know demons can't love?! Dont you know anything?! She liked me for who I was..*crosses his arms,murmurs* and even some of my own kind treat me like a king..and not a normal being.." The second figure growls and grabs Bill by the hand.

"You are not going back. Your not normal. The demons treat you differently because you are different in power and strength. No one messes with you,so why would you want this girl to mess with your heart?!" The second figure yelled.

Bill wipes his tears away, making eye contact with the second figure.

"I dont know." Bill stated softly.

The second figure sighs and opens a swirling portal.

"Good. You have to come with me. Once you step through,you will take your place as king. Your subjects need you. I need you." The second figure says softly.

Bill narrows his eyes and looks one last time at the Mystery Shack in front of him.

"Fine." Bill murmured.

The second figure steps into the portal, and extended his hand.

"Star,It's better I don't exist in your world. Because,I can't love you. A..demon and a human..can't. It's..not possible." Bill murmured under his breath.

He grabbed the second figures hand,as they step through. The portal slowly closing behind them.

Mabel sits,watching Dipper go next. She feels something under her pillow.

Taking it out,she scans it,and something new appeared. On the back,had the words,"Axolotl."
