Dipper opened his eyes and looked around the room. Seeing that it was morning, he looked at the clock on the nightstand to see that it was 7:45 AM. He got up and climbed to the top bunk to wake up his sister. "Mabel, get up!" he said as he shook her shoulder. "Get up, it's Monday!"

Mabel blearily lifted her eyes. Yawning, she rolled over to look Dipper in the eye. "Morning bro." she said as she got up and climbed down the stairs to start getting ready for school. "I hate normal days" she groaned as she put on a black sweater with a mouth sticking it's tongue out. Both of them had not yet gotten used to being at school again, as this was one month into seventh grade, and they were still used to strange things happening every day back at Stan's place in Gravity Falls.

The two rushed downstairs to find that their mother had just left for work and their father hadn't gotten up yet. Walking into the kitchen, Dipper took out two eggs and two strips of microwavable bacon. He lit the stove and cracked the eggs into a skillet, but before he could place the bacon in the microwave, Mabel stopped him.

"Dipper! Don't!" she shouted, slapping the bacon out of his hands. Dipper knew what Mabel meant, and he was sick of it.

"For the billionth time, this isn't Waddles!" he convinced her. "Soos is taking care of him, don't you remember?"

"I'm still worried!" said Mabel, "I can't bear to see someone eat Bacon without thinking of Waddles getting hurt!"

"Ok, whatever, sis." Dipper put the bacon back in the fridge. "We'll split the eggs."

"Thank you!" Mabel put one of those big smiles on her face which showed every one of her braces. When the eggs were fried, they put them down on the table and ate breakfast.

Dipper packed his homework in his backpack. Mabel saw this and then told him, "I don't think Mr. Deutscher will give you a good grade on your homework."

"But witches do exist! It's in the book!" he tried to convince her, but Mabel didn't think it was a good idea. She had to lie on her homework, as she made what the teacher would think of as the right answer, covering up the truth about what really happened that fateful summer in Salem back in 1692.

As they were finishing up their breakfast, they heard some growling upstairs. Both Dipper and mabel's eyes widened as they looked up at the ceiling to hear slow, heavy footsteps that caused the wooden floorboards to creak, as if they were back at the Mystery Shack and there was a monster lurking around upstairs.

"Oh no!" yelled Dipper in a panic, "Dad hasn't had his coffee yet!"

The twins quickly put on their backpacks and raincoats, and as they heard the heavy footsteps walking down the stairs, they tried not to look behind them.

Right as dad was about to reach the bottom of the stairs, Dipper and Mabel rushed out the door and started running down the street into the rain. They eventually stopped at the payphone where the school bus would pick them up.

"Dipper?" asked Mabel.

"Yeah?" Dipper replied.

"Are you worried that a monster is going to pop out of the bushes?" she looked into the deciduous woods across the street.

"Relax, sis." he said as he put his hand on her shoulder, trying to comfort her. "I am aware you're still used to our summer adventures. Now we're back at home in California, waiting in the rain for the school bus to arrive, and nothing strange is going to happen."

"Still, I get worried about things. Sometimes I worry about if Grunkle Stan's alright."

"Mabel, he's going to be just fine. Believe me." As he was saying this, Mabel noticed two lights behind the heavy rain that seemed to be getting closer and closer. Were they monster eyes? Nope. It was just the bus. She sighed in relief.

The doors opened. "Oh look, it's Bipper and Maple!" said the bus driver, who, for some reason, looked like a female version of Soos. They got on the bus and walked down an aisle full of noisy children. They sat down at a seat in the very back of the bus, across the aisle from Fregly, a boy who Mabel swore was like a younger version of Mr. McGucket.

"Aw man," Dipper said in disappointment, "taking the bus to school reminds me of taking the bus up to Gravity Falls."

"Me too, I miss our adventures there." Mabel told him, and then she looked out the window of the bus to see a sign showing how many miles it was to the Oregon border on I-5. This made her a bit upset, but she got even more unhappy when she saw a large billboard on the side of the highway advertising the Mystery Shack, showing Grunkle Stan spreading his arms out wide, as if to hug them. Dipper noticed this too, and they both began to tear up without having a single question on why Stan would advertise his tourist trap hundreds of miles south. "I miss the Mystery Shack." cried Mabel as she hugged her brother. "I can't handle to wait until next summer."

"Well, don't get too sad." Dipper unzipped his backpack. "I got something that can remind us of last summer and look forward to next summer." Mabel was shocked to see that he had been carrying all three of the books in his backpack.

"What? How'd you get those?" she asked in surprise.

"Grunks gave them to me before he left. He thought it would be in safer hands if I kept it for the school year?"

"That's not a very wise move." Mabel was starting to get a little worried on what would happen to the books. "Isn't it dangerous to keep those with you? Someone might try to steal them and use them against us."

"Relax, we've defeated Bill three times already, Gideon's in prison, and I doubt any culture or organization is after it."

"Still, I'm kind of scared that Bill will come back."

"Why?"

"Because our geometry teacher is obsessed with teaching triangles in geometry!"

Dipper hadn't noticed this before, and he felt kind of stupid that it took a month before Mabel could point it out to him. He knew that Mrs. Williams, their geometry teacher, was obsessed with triangles. Dipper and Mabel would notice triangles everywhere in her math class, on the board, on the homework, and even on her coffee mug. Although she was a big jerk to everyone, Dipper had noticed that she was the meanest to him and Mabel. All the students hated her. Whenever a student did bad on homework or a quiz, she would angrily throw it down on the floor and yell, "I could teach my dog to do better than this!"

As Dipper continued to think about a connection between Mrs. Williams and Bill Cipher, the bus pulled in at the school parking lot. Everyone got off and walked through the main entrance into the long and wide school hallway.

Dipper and Mabel opened their lockers. "Now remember" said Mabel, "Keep those books in your backpack and make sure your locker is locked. I don't want something bad to happen to them."

"Alright, I'll do it for you." Dipper took out his notebook, homework folder, and history textbook before he zipped up his backpack and closed his locker. Then they walked to Mr. Deutscher's social studies class, unaware of the witch-like geometry teacher watching them from the window of the door to her classroom.
