A/N: Due to the implication that The Legend of the Gnome Gemulets takes place between Northwest Mystery Mansion and Not What He Seems, here's a bonus chapter to fill in the gap.

It had been hours since the Southeast ball came to an end. And as promised, Dana and Patterson were in his room, watching all three movies and all twenty-six episodes of the Towards the Past series. The two kids were still wearing their formal wear, although Dana had to take off her painful crystal high heels. And at the moment, the first Towards the Past movie was almost coming to an end.

"Alright everyone. Here's a song you'll probably enjoy."

Dana squealed. She always loved the scene where Michael McFennek performed Jacob T. Coole at the Underwater Enchantment dance. It was such an awesome song and in her opinion, the vocals were better than the original version.

Patterson must have noticed Dana's excitement because as soon as the guitar began to play, he got up and dragged Dana up on her feet. The next thing she knew, they were dancing to the song.

As the two danced (with Dana giggling in delight), Preston and Priscilla watched them from the hallway. "I've never seen Patterson get this close with a girl," Priscilla said.

"Neither have I," Preston said. "He's actually smiling for once. Maybe it's time we initiate the big plan."

"But while Miss Pines did help us with our ghost problem, she's merely a commoner," Priscilla pointed out. "It'll never work."

"A lot of the guests thought she was a princess," Preston recalled. "She'll do."

The next day, at the Surprise Hut gift shop, Silvia was doing a quick attendance when she noticed someone was missing. "Where's Dana?" the sales artist asked.

"Weird," Marcus said. "I haven't seen her since last night. She should have come home by now."

As if on cue, Dana stumbled into the gift shop, exhausted. She had gone back to her old self, with her short-sleeved plain blue dress, sneakers, hat, messy hair, and makeup-free face. She let out a yawn. "Morning Graunt Silvia," she said.

"Oh my," Silvia said. "What happened to you, sweetie?"

"Just an awesome all-night Towards the Past marathon at Southeast Manor," Dana answered.

"Southeast Manor?!" Silvia asked, alarmed. "Why were you even there?!"

"I think I found out why," William said, looking at his phone. "Taylor just sent me this video."

Dana, Marcus, Silvia, and Salls walked over to William. The video was of Dana and Patterson's dance at last night's party. Dana's eyes widened. She recalled seeing Taylor and Becca at the party after Patterson opened the main gate. No wonder Taylor was able to record the dance!

William looked over at Dana. "Didn't want me to find out that you like dressing up?" he asked.

"The Southeasts forced me to wear that awful outfit!" Dana explained. "I was dolled up against my own free will!"

William chuckled. "Relax, Dana," he said. "You look much cuter the way you are now." He took off her hat, pushed aside her bangs, and kissed her birthmark.

Blushing, Dana snatched the hat from William. "You're just saying that to make me feel better," she said as she headed to her room.

Suddenly, the gift shop's phone rang. Silvia answered it. "Hello, this is the Surprise Hut," she said. "We put the fun in exploring. How may I help you?"

There was a long pause. Apparently whoever was on the other end had a lot to say. Time passed before Silvia spoke up again. "I see," she said. "I'll talk to her about it." She hung up the phone. "Dana, can you come down here?" she called out.

Dana got back in the gift shop, back to wearing her usual tomboyish outfit. "Yeah, Graunt Silvia?" she asked.

"Preston Southeast just called," Silvia explained. "Are you okay with taking part in a...fake wedding with Patterson this evening?"

"WHAT?!" Dana asked.

"Please don't shoot the messenger, sweetie," Silvia said. "The Southeasts have been planning an arranged marriage for their son for years. But last night, when they saw you hanging out with him, they figured you were a perfect fit."

"I can't marry Patterson!" Dana said. "He's a cool guy and he's as big of a Towards the Past fan as I am, but I don't like him in a romantic way! And what about William?! He's my boyfriend!"

"Aw, cheer up, Stargirl," Marcus said. "Maybe this is a good thing."

"Plus it's a fake wedding," William pointed out.

"And the Southeasts aren't that bad," Salls said. "At least that's what I've heard."

"Patterson seems to be the only good Southeast," Dana said, recalling last night's confrontation in the hidden room at Southeast Manor. "And besides, I'm not exactly rich girl material. They probably wouldn't approve of their son marrying a tough girl who has a strong punch."

"Preston said he'll plan everything out," Silvia said. "You won't have to lift a finger."

Over at Southeast Manor, Preston and Priscilla entered a secret room that had creepy tapestries on the walls. Preston took out a triangle-shaped bell and rang it. A deep voice echoed.

"LADIES AND GENTLEMEN, COMING TO YOU LIVE FROM SOME VERSION OF GRAVITY FALLS, IT'S THE ONE, THE ONLY, BIIIIIIIIIIIILL CIPHERRRRRRRRRRRRR!"

Bill appeared in a poof of smoke. "Thank you, thank you," he said. "I'll be here all week."

Preston cleared his throat. "Oh, right," Bill said. "So who am I speaking to this time? The Northwests or the Southeasts?"

"The Southeasts," Preston answered.

"Southeasts, huh?" Bill asked. "You two and your Dimension 46 counterparts are completely identical. Funny how not everyone has a genderswapped counterpart. Heck, turns out that despite some major differences in the past, the two dimensions seem to be in sync with one another."

"Bill, we don't have time for you bad-mouthing other dimensions," Preston said. "We have an important matter to discuss."

"Geez, talk about a mood-killer," Bill said. "So what is it this time? Ya want me to kill another bothersome pest?"

"Not this time," Preston answered. "We have decided to set up our son with an arranged marriage."

"Who's the lucky girl?" Bill asked. "Some rich bimbo who was raised from birth to be an obedient young lady?"

"You might know her," Priscilla said. "Her name is Dana Pines."

"WHAT?!" Bill asked. He started laughing. "You're joking! It'll never work! She'd probably punch him in the face again!"

"Not recently," Preston explained. "You see, they bonded over an 80s film franchise last night. And with many of the part guests mistaking her for a princess, my wife and I decided that she would be a perfect fit. So tonight we would like to set up a fake wedding for practice."

"Still won't work," Bill said. "I know the Southeasts have been devoted to me ever since I transformed Nicole from a waste-shoveling village idiot to a wealthy beauty, but there are some things I can't do. And forcing marriages to make sure they work isn't one of them."

"We had a different idea in mind," Preston continued. "Can you trick Dana into allowing you possession over her body?"

"Yeah right," Bill said. "I recently tried that trick with her Dimension 46 counterpart. I ended up getting tickled and exhausted. There's no way I'm making that same mistake again."

"Then can you at least strip her of her free will so she'll be okay with the marriage?" Priscilla suggested.

"Oh?" Bill asked, intrigued. "I never tried that before."

"So you'll do it?" Priscilla asked hopefully.

"'Course I'll do it!" Bill said, his hand being encased in bright blue flames. "Anything for two of my most loyal followers!" He proceeded to shake hands with Preston.

Back at the Surprise Hut, Dana and William were in the hut living room watching some TV. "Is it just me or does Gravity Falls TV only have the worst movies?" Dana asked.

"You're watching the Gravity Falls Bargain Movie Showcase. Coming up next: The Widdlest Wampire, The Planet People of Planet Planet!, Help! My Mummy's a Werewolf!, Attack of the Exclamation Points!, The Man with no Taste, Ghost Turtle, Help! My Mummy's a Werewolf! 2: This Again!"

"I really don't mind," William said. "Bad movies are fun to laugh at."

"That's only when there's commentary," Dana said. She changed the channel. "Maybe we can watch a repeat of Mysterious Sciencey Screening 1000 instead."

"That reminds me," William said. "How was last night's ball?"

"Seriously?" Dana asked. "You're still thinking about that?"

"The yearly Southeast ball is closed off from the rest of the town," William pointed out. "So how did a girl like you get in?"

Dana let out an exasperated sigh. "Long story short, the Southeasts were cursed to have a ghost haunting them, so they hired me to take care of it. I ended up helping Patterson lift the curse, then when everything was done, he offered a dance, and when the party was over, we spent the rest of the night having a Towards the Past marathon."

"According to Taylor's video, you seemed happy when you danced with Patterson," William pointed out.

Dana wasn't sure how to respond. She did, in fact, smile when she and Patterson danced during the ball. But what was William thinking? Was he jealous?

William must have noticed Dana's reaction. "It's okay," he said. "I respect that you have guy friends. And you've met Liz, Natalie, and Trisha. They're just my friends who happen to be girls."

Dana was surprised to hear that. "You're not jealous?" she asked.

William chuckled. "I would never be jealous of a 12-year-old," he said. "Besides, while you two can bond over your Towards the Past stuff, we still have Mysterious Sciencey Screening 1000."

"Yeah, I guess you're right," Dana said. But she still looked a bit unease.

"If it helps, this supposed wedding could help you practice for our possible wedding," William suggested.

"Our wedding?" Dana asked. "But William, I'm not even sure we'll actually have a wedding! I could end up with a different guy for all I know!"

"Dana, it's like what I said after the whole shape-shifter event," William said. "You're my dream girl. Someone who's smart, cute..." He took off her hat and let it drop to the floor before untying her long, messy brown hair and caressing his fingers through it. "...and has gorgeous brown hair."

"I wouldn't say it's 'gorgeous'," Dana said. "It's hard for me to manage it properly. There are too many knots and tangles in it."

"That's what makes you perfect," William said, still caressing Dana's hair. "You're nothing like the other girls I know. You don't wear makeup, you dress like a typical boy, you often act like one too, and you leave your hair in a natural style. I always wanted a girl like that."

Dana smiled softly. That was the first time a guy complimented on her looks, and she liked it very much. "Thanks," she said.

But while Dana and William watched the Mysterious Sciencey Screening 1000 version of Space Chasers, Bill had appeared in Dana's mind. He was becoming stronger, so he didn't need to wait for her to fall asleep.

"Look kid, you've been getting way too close to figuring out some major answers," Bill said, hoping Dana could hear him. "I've got big plans comin' and I don't need you gettin' in my way. Destroying that laptop was a cinch. Now I just need to destroy your free will."

But before Bill could do that, he noticed a door labeled SOUL. Curious, he decided to sneak a peak, so he floated over to the door and opened it. What he saw inside made him 'smile'.

"Oh..." Bill said. He laughed to himself. "So that's where my little seed was planted." Satisfied with what he saw, he closed the door and floated over to the MEMORIES door.

A Few Hours Later...

Silvia entered the living room. "Dana, there's a limo outside for you," she said. "I think the Southeasts are picking you up."

"Guess it's time," Dana said, tying her hair back up in a ponytail and putting her hat back on.

William held Dana's hand and gave it a gentle squeeze, making her look at him. "It's okay," he said. "If it helps, I'll attend the ceremony for moral support. Is that alright?"

Dana forced a smile. "Sure," she said. She looked back at Silvia. "But what about you, Marcus, and Salls?"

"I have to take care of important work, Marcus said something about meeting his girlfriend's parents, and Salls has to keep an eye on the Surprise Hut," Silvia explained. "I'm so sorry about not attending, sweetie."

"It's okay," Dana said. "I'm going to be alright."

And so, Dana and William arrived at Southeast Manor. The two entered the home, and they were greeted by the Southeasts.

"Hello Ms. Pines," Preston said. "And I see you brought an escort along."

"Hi Mr. and Mrs. Southeast," William said. "I'm William Corduroy. You might know my dad."

"Ah yes," Preston said. "Manly Dan the widower lumberjack. I know him all too well."

Priscilla walked over to Dana. "Come on, dear," she said. "I'll help you get ready for the wedding. We certainly can't have you looking like a filthy hobo."

After Priscilla and Dana left, William approached Patterson, who was wearing a while tuxedo. "So...what exactly do you see in Dana?" the red-haired teen asked Patterson.

"She's perfect," Patterson answered as Preston led led the two boys to a gazebo in the Southeast garden. "I initially didn't think much of her, but when I saw her in that blue butterfly gown last night, I realized she's capable of looking beautiful. Plus she's a huge Towards the Past fan and her geeky side makes her super cute. Too bad she's kinda out of my league."

"What?" William asked. "But you're Patterson Southeast, the richest boy in Gravity Falls."

"Yeah, and you're dating the prettiest girl in town," Patterson pointed out. "I mean, she would look like the prettiest girl in town if she brushes her hair more often."

"I think Dana looks fine the way she is," William said. "But you are right about her geeky side making her look cute."

"You should have seen her last night," Patterson said. "We danced to the Jacob T. Coole scene from the first Towards the Past movie, and she was giggling a lot."

"I don't know what that stuff means, but it sounds like fun," William said.

As the two boys continued to bond over Dana, she was in the Southeast dressing room with Priscilla. The 12-year-old girl was wearing a white poofy princess dress and shiny white high heels, with a diamond necklace worn around her neck and diamond eyeshadow on her eyelids. Right now Priscilla was brushing Dana's hair while the brunette girl sat by the room's vanity.

"I swear, it's like you haven't used conditioner every day," Priscilla said. She tied Dana's hair up in a bun, making sure every strand was in place.

"I don't," Dana said. "My hair is usually hard to manage. Marcus keeps saying that I should cut it, but I don't want people mistaking me for a boy."

"What a wise decision," Priscilla said. "I never understood girls these days. They're always cutting their hair short until they're bald. It's nice to hear that you plan on keeping your long hair."

"Really?" Dana asked, actually expecting the worst. "You're not going to scold me for disagreeing with society?"

"Why on Earth would I do that?" Priscilla asked in response. "I think your long hair is what makes you gorgeous. It would be a shame if it was chopped off."

Dana smiled. She never heard such a compliment towards her before. "Thanks," she said. She then noticed some foundation on the vanity. Having a sudden idea, she took the foundation, put some on a makeup brush, then lifted her bangs with the intention of covering her birthmark.

"What do you think you're doing?" Priscilla asked.

"Hiding my hideous birthmark," Dana answered. She was about to apply the makeup brush to her forehead when Priscilla grabbed her wrist.

"Don't you dare cover that birthmark," she said. "It's the most beautiful natural marking I ever saw."

"It's not beautiful," Dana said. "It's the reason why I gave myself bangs. Kids used to make fun of it before I started hiding it all the time. Even my parents told me the birthmark was what made me a freak."

Priscilla looked alarmed. "How dare they say such words!" she said. "You should be proud to have such a birthmark!" She picked up a sapphire barrette and used it to clip back Dana's bangs. "See? Isn't that better than foundation?"

Dana looked at her reflection. She never thought of her birthmark as beautiful. And she had to admit that Priscilla was right. Plus the sapphire barrette made her eyes sparkle.

"I take it that you don't get a lot of compliments," Priscilla said.

Dana slowly shook her head 'no'.

"That would explain the lack of care in looks," Priscilla said. "Tell you what, dear. Keep the barrette. Think of it as a reminder that you are a very pretty young lady. Now come on. You don't want to be late for your wedding."

And so, Priscilla brought Dana to the Southeast garden, which was nicely lit. The older woman led Dana down the aisle as soft music played from a boom box. And as Dana walked, she noticed there were random citizens in the chairs. She also noticed both Patterson and William were staring at her. She knew why. It was probably because of how pretty she looked.

When Dana finally reached Patterson and Priscilla stood on the side next to Preston, the Gravity Falls priest began the unofficial ceremony.

But during the ceremony, William noticed there was something off about Dana. She frequently blinking for some unknown reason. He knew people blink, but she was blinking rather oddly, only blinking one eye at a time. But he remained silent the entire time, not wanting to interrupt the wedding.

Eventually, it was time for the famous words. "Do you, Patterson Elliot Southeast, take Dana to be your wife?" the priest asked.

"I do," Patterson said, although it looked like he regret saying that.

"And do you, Dana Pines, take Patterson to be your husband?" the priest asked.

But Dana didn't respond. It was as if she froze up. "Don't tell me your getting wedding jitters," Patterson whispered.

"Ms. Pines, we need a response," the priest said.

Dana still didn't respond. "Come on, Dana," Patterson said. "Say something." He gently patted her cheek. She responded with that, backing up abruptly.

"Watch it, kid! Don't break my new doll!"

That voice sounded nothing like Dana. Sure enough, her eyes had become yellow with slitted pupils. It was none other than Bill Cipher!

William stood forward, immediately noticing the change in Dana's eyes. "Who are you, you imposter?!" he asked.

"Oh, right," Bill said. "Name's Bill Cipher, and I was summoned to make sure little miss tomboy here wouldn't hesitate to marry the blonde rich boy. But don't worry. She's still in here."

Bill let Dana get control for a brief time. "Get out of my head!" she exclaimed before Bill took over once more.

"Oh be quiet, Sketchpad," Bill said. "Now then, as long as I'm in this girl's body, I can do whatever I want. Watch!" He proceeded to sing.

If your birth was an accident and you know it, clap your hands!

CLAP CLAP

If nobody really loves you and you know it, clap your hands!

CLAP CLAP

If you're such a big disgrace,
And your whole life's been a waste,
If nobody's gonna miss you, clap your hands!

CLAP CLAP

Everyone was shocked. "Oh, and it might be because of this special little birthmark over here," Bill said, gesturing to Dana's birthmark.

"That's a birthmark?" Patterson asked. "I thought it was some kind of temporary tattoo."

"Nope," William said. "That's Dana's birthmark. It's why Marcus calls her 'Stargirl'."

Upon hearing William's voice, Dana regained control. "William, do something!" she begged.

Not sure on what he should do, William did the only thing he could do. He walked over to Dana as Patterson stepped aside. "It's okay," he said soothingly. He kneeled down to her level and hugged her. "I'm here."

"Nice try," Bill said. "You really think the 'power of love' can stop me? I'm an all-powerful dream demon! I lost that feeling years ago!"

"Don't listen to him, Dana," William said. "You can fight this. I don't know who this Bill Cipher guy is, but you are strong enough to fight back!"

To Bill's surprise, Dana's arms moved to hug William back. "What?!" he asked, alarmed. "Why can't I control this pile of flesh anymore?!"

Seeing that Dana's love for him was strong, William loosened her hair, changing it from a bun to a ponytail. "There's the tomboy I love," he said.

"I revealed this girl's secrets!" Bill cried out. "How could you still love her after that?!"

William didn't respond. Instead, he kissed her birthmark, which gave Dana enough strength to kick Bill out of her head. She inhaled deeply as she regained full control of her body.

"Dana!" William happily explained. He stood to his full height and picked up Dana, carrying her bridal style. He started kissing her cheeks multiple times. But then he noticed she wasn't smiling.

"What's wrong?" William asked as he placed Dana back on the ground.

"It's us," Dana explained. "You still love me."

"Come on Dana," William said. "You begged for my help while Bill was inside your mind."

"I was scared!" Dana exclaimed. "Look, I still think that us as a couple won't work out in the future! Worse, you now know I'm not this perfect little princess you thought I was! I'm a living Cinderella and my parents hate me so much that they never gave me an official name! 'Dana' is just something Marcus started calling me before we started school!" She turned away, tears coming from her eyes.

William cupped Dana's chin and made her look back at him. He didn't care about the forming white streaks on her face. "So what if you don't have a name?" he asked. "You're still Dana Pines, and you're still my girl."

Dana pulled away. "But for how long?" she asked. "You're probably just a summer romance."

"Oh for Pete's sake!" Patterson complained. He walked over to the priest. "Can you marry Dana to William instead of me?" the blonde boy asked.

Everyone was shocked to hear that. "Seriously Patterson?" Dana asked. "Now?"

"You're too concerned about losing William in the future," Patterson said. "Why not marry the guy now?"

"I don't know..." Dana said. "Marcus would get upset if he found out I participated in an illegal wedding ceremony..."

"The union can't be declared a legal binding in any state or county," the priest explained. "However, the commitments and vows you would be making if you go through with this will be seen as all-too real. And, at least in Gravity Falls, you will be expected to honor those commitments."

"So what do you say?" William asked. "Will you unofficially marry me?"

Dana looked up at William. If she was to participate in this, she would be expected to commit to this relationship. But after much thought, she made her decision.

"Alright William," Dana said. "I will marry you, but not like this. Not as this false image."

"Very well," Preston said. "Patterson, make sure William is properly dressed. We have a fake wedding to prepare."

And so, like before, Priscilla helped Dana get ready for the unofficial ceremony in the Southeast dressing room, but on the brunette girl's terms. As a result of this, she wore a sleeveless white dress with a light blue bow tied around the waist and diamond flats. Her hair was down and done in soft curls, and her face was free of makeup. She also didn't wear any jewelry.

But just as she was about to head back to the garden, Dana realized her bangs were getting a big long. She picked up a pair of scissors on the vanity.

"I see you want to still have bangs," Priscilla commented.

Dana nodded in response. "Having bangs is the only way to get people to stop laughing at me," she explained. "My hair ended up looking so ugly afterwards when I got them, but Marcus fixed it by putting it up in a cute ponytail."

Priscilla took the scissors out of Dana's hand and replaced it with the sapphire barrette. "Your birthmark is what makes you prettier," the wealthy woman encouraged. "And if you think your bangs make you look ugly, maybe it's time to grow them out."

Dana looked at her reflection in the vanity mirror. Maybe Priscilla was right. Maybe it was time for a change. So the brunette girl used the barrette to clip her bangs away from her forehead, exposing her birthmark once more. "Thanks Mrs. Southeast," she said, smiling at how pretty she looked.

Back in the garden, everyone was in position. When the music played from the boom box, Dana walked down the aisle by herself. All eyes were on her, and she felt absolutely beautiful. She no longer worried about her birthmark. Instead, she decided to embrace what make her special.

When Dana saw William, she was amazed with how much he changed for the wedding. He looked downright handsome in a black and white suit, and his chin-length hair was gelled back. Dana had to assume that the gel was William's idea, since he once admitted that he doesn't look good with shorter hair.

When Dana finally reached William, she looked up at him and he looked down at her as the ceremony began. "Dearly beloved," the priest said. "We're all here this evening to celebrate the relationship of Ms. Dana Pines and Mr. William Corduroy and to be witnesses and supporters of the commitment they share with one another."

The ceremony went off without a hitch. When it was time for the vows, Dana and William improvised their own vows.

"With this hand, I will lift your sorrows," Dana said, quoting the vows from the Tom Burten animated classic Zombie Bride. "Your cup will never be empty, for I will be your wine. With this candle, I will light your way into darkness." She held up a silver ring and placed it on William's finger. "With this ring, I ask you to be mine."

"Really?" William whisper. "Zombie Bride?"

"They were the first vows that popped into my head," Dana whispered back.

William chuckled before he said his vows. "Dana, with all my love, I take you to be my wife," he said. "I will love you through good and the bad, through joy and the sorrow. I will try to be understanding, and to trust in you completely. Together we will face all of life's experiences and share one another's dreams and goals. I promise I will be your equal partner in a loving, honest relationship, for as long as we both shall live." He held up a diamond ring and placed it on Dana's finger.

"Dana and William you have professed your love by exchanging your vows," the priest said. "You have symbolized your commitment by exchanging rings. And you have expressed the end of your individual lives by the pouring of the unity sand. With all of this there is just one more question I need each of you to answer.

"William – do you take this young girl to be your wife; to live together in the covenant of marriage? Do you promise to love her, comfort her, honor and keep her, in sickness and in health; and, forsaking all others, be faithful to her as long as you both shall live?"

"I do," William said confidently.

"Dana – do you take this teenage boy to be your husband; to live together in the covenant of marriage?" the priest asked. "Do you promise to love him, comfort him, honor and keep him, in sickness and in health; and, forsaking all others, be faithful to him as long as you both shall live?"

Dana smiled wide. "I do," she said, her naturally high-pitched voice squeaking.

"Then the power vested in me, in the state of Oregon, I now pronounce you unofficial husband and wife," the priest said.

William leaned down to Dana's level and kissed her. And as Dana kissed back, she had a pretty good feeling that things were going to turn out alright in the future.
