My Teacher's an Alien

by Boolia

It's Mabel's and Dipper's (Mason) first day of eighth grade. Mabel makes new friends, and Dipper meets his new crush. When missing the bus ride home from school one day, Mabel discovers something shocking, that her new science teacher, Miss. Smith, is an alien from another planet! Set after the series finale. Dipper is still referred to as 'Dipper'.

2. Part 2

Part 2

Mabel and one of her teachers waited on the front stoop when her mother's car pulled up in the school's parking lot. She went into the car. Dipper was there.

"Hey, Mabel." Dipper greeted her as she buckled her seatbelt. She looked at him, mad.

"Didn't you tell the bus driver that she left me?!" She asked.

"I'm sorry, Mabel, but I didn't realize you weren't with me until it was the first stop. You okay?"

"No; I missed the school bus home, do you think I'm okay?!" Dipper sighed.

"Sorry I asked." Mabel then changed the subject, changing into her cheery mood.

"Guess what I discovered about my science teacher, Miss. Smith?"

"What?"

"That she's an alien." Dipper was confused.

"What?"

"An alien. You know, from outer space." Dipper was about to ask more when their mother spoke up after she finished talking to Mabel's teacher. She was driving.

"So," She said. "Missed the school bus, did we?" Mabel sighed.

"Yeah." Mabel admitted to her. "I had to go to the bathroom."

"You couldn't hold it in for ten more minutes?" Dipper questioned. Mabel shook her head.

"I really had to go. Otherwise I might have had an accident on the bus." Dipper looked disgusted.

"Yeah; good thing you went when you did."

"So, did you finish your homework while you waited?" Mrs. Pines wanted to know.

"Almost." Mabel told her. "I just have to finish a chapter from The Boarman."

"That's good."

"Yeah." Mabel thought of something else. "Oh! And guess what I just found out?"

"What?" Her mother wanted to know.

"I found out that Miss. Smith, my science teacher is an ali…" But Dipper put his hand over her sister's mouth, forcing her to mumble.

"Your teacher is a what?"

"Nothing, Mom!" Dipper told her. He released his hand over Mabel's mouth. Mabel looked at him.

"Why did you do that?" She asked.

"Because you were about to tell Mom who your teacher really is."

"So?"

"So? Mabel, you don't do that. She'll think you're nuts. She'll tell Dad, and if you continue referring to your teacher as an alien, you'll get sent to a psychiatrist."

"But I wrote to Mom and Dad about the crazy stuff in Gravity Falls."

"That's because they might have thought you were just making them up just to spice up things up." Mabel then chuckled. Dipper was confused. "What?"

"Oh, nothing. I was just thinking it would be funny if there was a city or a town in Oregon called Boring."

"Yeah, I guess that would be a weird name to call a town, or city. But, that's beside the point. You just can't go blabbing to everyone that you see that your teacher is an alien. This isn't Gravity Falls. This is Piedmont, California."

"Can I tell Grunkle Stan and Grunkle Ford?"

"Sure. Just tell them, and nobody else. Understand? Promise me that you won't tell anybody else, except maybe Soos and Wendy."

"But…"

"Promise me!" Mabel sighed. Her brother's eyes telling her that he was serious.

"I promise."

That night after dinner, Mabel chatted with her grunkles, and Candy and Grenda online, and told them about her teacher being an alien. She talked and talked until her bedtime. She also told Waddles about it.

The next day at lunch, Mabel told her friends the news about Miss. Smith. They just looked at her as she clasped her hands in front of her mouth. She didn't mean to tell them. It just blurted out of her. She couldn't help it. Then again, these are her friends. Surly she could trust them not to tell, right? Mabel looked at her friends. Of course she could trust them. That's what friends do. They trust each other.

"What?" Reese wanted to know.

"Miss. Smith's an alien." Mabel repeated.

"An alien?" Kit questioned. "You mean from outer space?" Mabel nodded. "You're serious?" Mabel nodded again. "How do you know?" Mabel told them everything.

"Yeah, right!" They heard someone say. They looked up. It was Atlantica. She just threw her food away.

"Atlantica! How much did you hear?"

"Everything."

"You won't tell anyone, right? I promised Dipper that I wouldn't let anyone know."

"Then why did you tell these two?"

"Because they are my friends."

"Oh." She then was confused. "Who's Dipper?"

"Mason. Dipper is his nickname."

"Dipper?" Mabel nodded.

"Yeah, so don't tell anyone about Miss. Smith okay?" Atlanica nodded.

"Oh, I won't, weirdo," Mabel smiled.

"Thanks."

But, as soon as Atlantica got back to her table, that's exactly is what she told her friends. They then told other students after lunch…who told more students…who told even more students. Pretty soon the most of the eighth grade knew, even some of the kids in the other grades. Dipper was the last to know.

Dipper was walking down the hallway when he overheard some kids talking about Miss. Smith.

"What about Miss. Smith?" He wanted to know when he went up to a group of kids.

"Did you hear?" A kid questioned. Dipper shook his head.

"Everyone's taking about it. Miss. Smith's an alien." Dipper chuckled nervously.

"Miss. Smith? An alien? Yeah, right; it's a rumor. You don't actually believe it, do you? Where did you hear about this?" He didn't get an answer, for that is when the one- minute warning bell rang. They, along with other kids ran to their homerooms. Dipper sighed, and he too, headed towards his homeroom.

Dipper sat at his desk. He heard more kids talking about Miss. Smith being an alien. A kid ran up to him.

"Dipper, did you hear?" She wanted to know.

"That Miss. Smith, the eighth grade science teacher, is an alien?" He guessed. "Yeah, I heard."

"It makes you wonder, doesn't it? That there is other life on other planets, you know?"

"Yeah." He agreed. The kid then left. Dipper sighed, and put his head on his desk. Mabel saw this, and felt bad. She went over to him.

"Dipper?" She asked. Dipper looked at her.

"You told them, didn't you?" He asked.

"Well, I only told our friends from Gravity Falls, and Kit and Reese."

"You told your friends?"

"Well, there're my friends; I had to tell them! I trust them."

"But, Mabel, school just started, and you just met them a couple days ago, and already you're trusting them?"

"Yeah." Dipper sighed. "I'm sorry, Dipper."

"Did you tell anyone else?" Mabel shook her head.

"No. This is bad, isn't it?"

"Yes, the whole school will probably know now."

"I'll go ask Kit and Reese if they told, but I'm sure they didn't tell anyone else." She went off.

The TV with their school news came on then. One segment was about Miss. Smith.

"Oh, no!" Dipper said to himself. "Not the whole school!"

The scene then shifted to an interview with Atlantica and another student, Abigail Banks.

The school bell rang after the news was over, and Dipper got out of his desk. He headed out of the room.

"Dipper, I didn't tell Atlantica." She told her brother. "What are we going to do?" But, Dipper was too mad to answer. "Dipper!"

"Mabel?" Miss. Smith asked her at science class. She and the other kids were doing an assignment. She went out of her desk, and went to her teacher.

"Yes, Miss. Smith?" She wanted to know. Miss. Smith ushered her to follow her, and Mabel did. "What is this about, Miss. Smith?" Miss Smith grabbed her arm, and pulled her close. "Ow! Miss. Smith, you're hurting me?"

"How do you know?!"

"How do I know what? Can you let me go, now? You're very strong!"

"Not until your answer the question, little earthling. How do you know about me being an alien?!" So, Mabel told her what she saw yesterday. Miss. Smith released her. Mabel nursed her arm.

"This is not good." Miss. Smith told her. "I have to leave, but I don't want to."

"Then don't!" Miss. Smith looked at her.

"You don't understand. It's been my lifelong dream to be a teacher, and we don't have school where I'm from."

"You don't?" Miss Smith nodded. "So, don't leave, stay on Earth. I don't understand." Miss Smith sighed, and looked at her.

"They know that I'm an alien now. If my dad find out, he'll force me to come back home, only I hate it there. I like this planet better."

"Then they don't have to know. Plus, not everybody knows. Only the ones who saw the TV."

"Tee-Vee? Is that what you earthlings call the moving picture box?" Mabel nodded.

"So, please don't leave, please? I never had an alien as my teacher before, and I think that it is the coolest thing ever!"

"Well, if my dad finds out, and/or others want to do some experiments on me, I'll have to leave. Do you think that'll happen?" Mabel shook her head.

"I have a pretty good idea who told on you. With a good talking to, I'm sure she'll stop, and this ugly mess will be all over with."

"You trust her?" Mabel nodded.

"We're friends, and friends trust each other."

"I hope you know what you're doing."

"Trust me, I do." Miss. Smith smiled at her.

"Thanks, Mabel." Mabel smiled back. They then went back to their desks in the classroom.

"Atlantica!" Mabel said to her as soon as class was done. Kids were leaving, and getting ready to go home. Atlantica sighed. She looked at her friends.

"Sorry, girls." She told them. "Granny Mabel's going to talk to me. I'll see you on the bus." Her friends left. Atlantica looked at Mabel. "So? Out with it! What do you want?" Mabel was mad.

"Why did you tell our peers about Miss Smith? I told you not to."

"Oh, I know you did. But, I still told."

"Why? I thought we were friends." Atlantica laughed.

"What made you think we were friends? We were never friends, okay? And we never will be!" Mabel narrowed her eyes.

"I should've known, considering you're related to Pacifica. Pacifica and I weren't friends either, but we warmed up to each other. I thought you and I could do the same."

"Well, you thought wrong! Why Pacifica made you into a friend at the end, I have no idea."

"Well, Miss. Smith doesn't want everybody knowing her secret, otherwise she'll have to go home."

"So? She's an alien; people have to know."

"No, they don't. It's her lifelong dream to teach students, and they don't have a school on her planet."

"So? I don't care."

"I promised her that I'll talk you out of this."

"Well, you shouldn't have promised her that!" She began to leave.

"So, you won't tell, right?" But, she didn't get an answer. "Atlantica?" Atlantica left the room. Mabel huffed, and went off herself.

"Did you talk to the one who blabbed?" Miss. Smith asked her in the hallway.

"Yeah, I did."

"So? Is she going to stop spreading this around?" Mabel just looked at her. "Please, I need to know, so I can know if I should leave or not."

"She promised she wouldn't tell any more people." Miss Smith smiled.

"Oh, thank you, Mabel! See you tomorrow." She then left. Mabel sighed.

"Yeah. See you tomorrow." She resumed on towards her locker. She shouldn't have lied to her; she knew that, and felt guilty. But, she couldn't help it. She didn't want her teacher to leave, and give up on her dream either. After all it's not every day that you get an alien for a teacher.

"Hey, kids!" Mr. Pines called for his two kids. He and Mrs. Pines were watching the news. Dipper and Mabel rushed into the room.

"Yeah, Dad?" Dipper asked. "What is it?" Their dad pointed to the TV.

"There's a girl on the news that goes to your school. Do you know her?" Mabel and Dipper looked at the TV. They instantly recognized Atlantica about to be interviewed. Mabel scowled.

"Atlantica!" She murmured under her breath.

"What's Atlantica doing on the news?" Dipper wanted to know. When he read the caption underneath 'are there other life forms living among us? ', it answered his question.

"Oh no!" He said, looking back at the TV. "I should've known that this was coming."

"So, Atlantica," The interviewer asked her in a microphone. "How did you discover that your science teacher, is an alien?" She offered Atlantica the mike.

"A classmate of mine Mabel Pines told me." She lied.

"I did not!" Mabel blurted out. "That's not true; she's lying on national television!"

"Mabel, shhhh!" Her mom said to her. "Let's just listen to what your friend has to say." Mabel crossed her hands across her chest.

"She's not my friend! She even said so herself."

"Mabel, please!" They paid attention to the TV again.

"And do you have evidence of this?" The interviewer continued. Atantica nodded.

"As a matter of fact, Sharon, I do." She got out her cellphone, and handed it to her when she found the picture. Sharon examined it, her eyes wide. "Wow! If this isn't suspicious evidence, I don't know what is." She looked at the audience. "Take a look folks; evidence of a UFO!" The TV then showed a picture of Miss. Smith's UFO zooming above Piedmont Middle School. Sharon gave Atlantica her cellphone back, and asked if she had more evidence. Atlantica shook her head.

"No. Sorry, that's all I have."

"Well, thank you for this out of this world news." They then shook hands.

"No problem! It was an honor to be on television. I never was on the news before."

"Well, I'm glad you liked it. Maybe you'll be on it when you're older too. Never say never." Sharon looked at the audience again. "Now, a special guest is in the studio ready to give his insights on possible alien life. Here's conspiracy theorist, Ed Gryson!" The TV then flipped to the studio with the news people, and Ed Gryson, a balding man with black thick glasses.

Ed talked about lots of stuff related to aliens. He talked about the possible things they made like Stonehenge, and the Egyptian Pyramids. He talked about Area 51, and other alien sightings throughout history.

"Now, we're not saying that aliens exist." Ed said. "But we're not saying they don't either. Our universe is very big, so it is a huge possibility that we are not alone."

"Thank you, Ed for that interesting speech." A news anchor told him. "It was a pleasure that you could do this."

"Well, it's a pleasure to be here as well." Ed responded. They all shook hands. "I really like what I do. I always wanted to do this as a kid. I find it interesting that there may be other life out there."

"Well, I'm glad you're living your dream."

"Me too." Said a newswoman.

"Me three." Added the third. She looked at the camera. "And now for sports!"

"Mabel," Mr. Pines started after his wife turned down the volume of the TV. He and Mrs. Pines looked at their daughter. "Did you tell Atlantica that your teacher is an alien?"

"I already told you that I didn't!" Mabel snapped.

"Mabel," Mrs. Pines started.

"Just back off!" She ran to her bedroom. Waddles waddled after the young teen. Mr. Pines just shrugged.

"Well, she's officially a teenager now."

The next day in science, Mabel and her friends saw their principal instead of Miss. Smith.

"What's Mr. Jay doing here?" Mabel wanted to know. Both Kit and Reese shrugged. Mabel was about to ask, when Mr. Jay told everyone to sit down after the bell rang. Kids took their seat. Mr. Jay called on Mabel with a question.

"Why are you here?" She asked.

"I'm your substitute for the day."

"Where's Miss. Smith?" Mr. Jay shrugged.

"I don't know. She never came in today. And we couldn't get a sub today, so, I stepped in instead."

"But, aren't you busy with other stuff? Like, doing things whatever school principals do?"

"I do usually, but I couldn't leave you kids with no teacher here. If I do that, it'll be chaos. You kids will be goofing off all the time instead of learning."

"I read a book where the teacher didn't show up." A boy stated when the principal called on him. "They managed alright, provided there were some goofing off. But, what do you expect with kids with no one telling them what to do?"

"Well, I'm not leaving this class, so there will be no flying solo, today." All of the kids groaned. "Now, onto your lesson. Can someone please tell me what Miss. Smith's been teaching you?" Hands shot up. Mr. Jay called on the same girl who questioned Miss. Smith the first day.

Where's Miss Smith? Mabel thought. Is she sick, and forgot to call in? Mabel shrugged it off. Oh well, maybe she'll be at school tomorrow.

But, she wasn't at the school the next day, or the next, or the next. In fact, Miss. Smith wasn't there for the rest of the month.

On the first day of October, Mabel and Dipper's homeroom teacher told the class that the first school newspaper of the year was in, and they should get them off her desk if they wanted one.

When the bell rang, Dipper, newspaper in hand, showed his sister an article in it.

"Look!" He said. Mabel looked at it. Her eyes widened as she read the title of the article: 'Is Miss Smith an Alien?'. She grabbed it from him, and looked it over. She looked at her brother.

"You don't think she left because of all of this do you?" She wanted to know. Dipper shrugged.

"It's a possibility." He said.

"But, it's her dream to teach earth students. She can't give it up just because she's been exposed." Again, Dipper shrugged.

"I don't know what to tell you, Mabel. You can't change people, or in this case, alien's minds. They can decide for themselves."

"But…"

"Some dreams can't come true. Now, I have to go to class," He grabbed the newspaper back from his twin. "and I suggest you do the same." He then left the room.

Mabel was going towards her school bus after school the next day, when she heard faint arguing. She looked around the corner where she had discovered the UFO, and saw that it was Mss. Smith, and smiled. Miss. Smith was arguing with a spiky haired man. Mabel looked at her watch. It was five minutes until her bus was scheduled to leave, so she went towards her bickering teacher, and the spiky haired man.

"Excuse me!" She began. Her teacher and the man looked at her.

"Who's this?" The man wanted to now. Miss. Smith looked at him.

"This, Father, is Mabel Pines." Miss. Smith introduced. "She is one of my pupils." Mabel was confused, as she looked at the man.

"He's your dad?" She asked. Miss. Smith nodded.

"Is this the earth child who blabbed to the world on your background?" Miss. Smith's father questioned.

"I only told those that I trust." Mabel told him. "I'm so sorry. I didn't mean for it to get out of hand."

"Well, it did." The dad said. "And now your teacher is leaving. I'm taking her home back to our planet."

"Father, please!" Miss. Smith begged.

"You can't!" Mabel added. "It's her dream to teach us students. Don't take it away because of this. There must be another way."

"I'm sorry, child." The dad told her. "There isn't another way. She has to come back to her planet."

"But, Father," Miss Smith spoke. "I hate our planet!" Miss. Smith's father looked at her in shock.

"But, Zenonie, you love the planet where you were born on."

"No, Dad!" Zenonie disagreed. "You, Mom, and my siblings love our planet. I hate it, and I always had, and always will!"

"I never thought you felt this way."

"Well, I do. I like Earth better, and will never go back to that horrid planet!" Mabel was confused. She looked at her teacher.

"Your name is Zenonie?" She questioned. "I thought it was Kiki Lexi Smith." Zenonie looked at her.

"I chose that as my human name." Zenonie explained. "Zenonie is my alien name."

"I'm sorry, Zenonie." Her father told her. "But, it's too risky to stay here. You're coming back home, and that's final!"

"But, Father!" Her dad glared at her.

"Zenonie!" Zenonie sighed.

"Yes, Father."

"Good. You go get your things. I'll be waiting for you on the ship." And with that, he went on the UFO. Mabel looked at her teacher.

"You're not really leaving, are you?" She wanted to know. Zenonie looked at her, sadness in her eyes.

"I'm afraid I don't have a choice."

"But, you can't go; you have to stay here, and fulfill your dream!"

"I'm sorry; I would if I could."

"So, that's it? Why don't you think about it?"

"I'm pretty sure this is it. My father's mind is made up."

"Oh, please, think about it!"

"Well, I don't know."

"Please! Don't give up on your dream!"

"I…" But, Zenonie couldn't argue with the hopeful look that Mabel was giving her. She sighed. "Alright; I'll think about it." Mabel cheered.

"Yay; I promise you won't regret it!" She turned to go to her bus, when she saw the bus beginning to leave.

"WAIT!" She ran after her bus. She stopped when her bus sped up. She stopped. "Shoot! Missed it again."

"Awe; missed the bus?" Zenonie observed from behind. "That's too bad." Mabel then hatched an idea in her head. She turned to Zenonie.

"Can you take me home?" She asked.

"You want us to take your to your house?" Mabel nodded.

"Uh-huh! I never rode in an alien spaceship before. It'll be so cool!" Zenonie thought about this.

"Well, I have to ask my Dad."

"Zenonie!" Her father called from inside the ship. "Get your alien behind in here!"

"Coming!" Zenonie called. She looked at Mabel. "Well, come on if you're coming!" Mabel beamed.

"Yay; my first ride in a real life UFO!" With that, she and Zenonie went to the UFO.

Once in, Mabel looked around the whole UFO. She barely could contain her excitement. She couldn't believe her eyes. The two aliens were back in their alien forms. Zenonie's dad was like her, but a bit taller and green.

"Wow; cool!" Mabel marveled, running and looking at everything on board. "Dipper will be so jealous; this is out of this word!"

"Zenonie!" Her father scolded when she saw Mabel. Zenonie went to him.

"Yes, Father?" She asked.

"What's the earth girl doing here?"

"She missed her ride home in one of those big, yellow transportation contraptions."

"Yeah, so?"

"She asked for a ride home, and I told her I needed your permission first."

"But, why did you tell her that? We're going to our home planet, not her house."

"Because I felt bad that she missed her ride home. We can take a detour. It won't be long."

"Why doesn't she walk home?"'

"Well, I don't know. I'll ask." She looked at Mabel. "Hey, Mabel, why don't you walk home?"

"Are you kidding?!" Mabel answered. "It's like a bazillion miles to my house. It'll take me forever to get home." Zenonie looked at her father.

"She said it's a bazillion miles to her house." She told him. "She said it'd take her forever to get home."

"Well, tell her she'll has to walk those bazillion miles. We're not taking her home." Zenonie looked at her dad in shock.

"Father!"

"I'm sorry, but my mind's been made. We're not taking her home."

"Father; please! It'll be brief. Once we drop her off…" She sighed. "We'll go back to our planet. I promise."

"No! We drop her off here, and make her walk home, Zenonie! That is fina…" But, Zenonie's dad couldn't argue with the hopeful look that his daughter was giving him. He sighed.

"Fine; we'll take her home." Zenonie beamed.

"Oh, thank you, Father! She'll be happy. You're doing a good deed."

"Yeah; yeah; but we're not staying there. We're just taking her home, understand?" Zenonie nodded.

"Understood. Taking her home was my only plan."

"Good."

"Well, Mabel," Zenonie said when they were in the backyard of the Pine's house. "It was nice seeing the school again, that's why I came, to look at the school one last time, and the students. This is goodbye."

"But, this isn't your last time. You're going to teach, and come back, right?"

"We'll see."

"Well, think about it!"

"We'll see." They bid their goodbyes.

"Zenonie!" Her father shouted from the ship.

"Coming, Dad!" The alien called to her dad, and left.

"Remember to think it over!" Mabel called.

"I will!" She went onto the ship. The UFO took off. Zenonie saw Mabel, waving at her from the window. She sighed.

"I'm sorry, Mabel."
