Mysteries (Bill x Fem!Dipper)

First Day of School: Part 2

Previously:

Dipper snickered at her twin sister.Mabel pouted.

"C'mon let's go to class-Ow!"

"Hey watch where your'e going!"

=====================================================================================

Dipper stood up to 'talk' to the one who bumped into her before she could process the situation Mabel suddenly shouted. "Pat hi! How are you? how's England? How do you pronounce Crumpets?" Her eyes twinkling in delight. "Oh Hi Mabel I'm Fine thank you for greeting me.Hello Dipper it's nice to see you again and I'm sorry for bumping into you."

He smiled at her direction, Dipper relaxed a bit before saying "Hey Pat still rich and girly as ever!" She playfully smacked his back. "Heh and your tomboy as ever I see." "Shuddup!" Dipper shuddered when his fanclub or the 'Blonde Protection Club' Glared and muttering darkly at Dipper and Mabel.

"Hey Pat what's your Class?" Mabel said looking over Patrick's shoulder.He pulled out a neat folded paper from his blue jacket. "I got History it's Class B-4 on the left hallway." Mabel had a devilish smile on her face. Without any warning Mabel hopped on Pat's back like a cowgirl on a horse and then said "Tally Ho!My Blonde friend!"Everyone in the hallway was looking at Mabel with a confused expression 'Pretend that you don't know them,Pretend that you don't know them.' Dipper thought pleading to God.

Even though people looked at them, they still went to the History Class while laughing and Pat's Fan girls crying silently and following them from the shadows."I guess nobody is safe from Mabel.." she sighed loudly.'Wait what time is it? Oh S*** I have to go to class!' She thought before dashing through the hallway to go to the Math Class as the school bell rang loudly.

Just as the teacher was about to go in she got a chair at the far back beside the windows and panted slowly when she sat down on the chair.

"Okay class I am Ms.Myers your Math teacher for this School year, hope we can get along.To start our lesson for today please turn your book on page 349 section A."She continued not noticing the students not listening to her.

Now if you look closely at the equation....." Dipper's mind was drifting away thinking about the past summer's discoveries like the Height Altering Crystals or when the Mind Reading Tulips of the Leprocorns.(The last one was made up) Her eyes slowly closing but she wants to wake up. Desperately wanting no to get caught she tugged on her jacket's sleeve revealing ancient runes in permanent ink.

'Why did I use this kind of ink again?' she thought as she rubbed it off.Grunkle Ford was not happy when he learned about it.Luckily the ink could be hidden or erased by unicorn blood and the smell is unpleasant.Dipper shivered ,Ms.Myers noticed Dipper's shiver and called her out to answer the equation on the board."Ms.Pines since you weren't listening please answer this equation." She saw the board then turned into a white statue because of shock of what was written on the board.Dipper quickly realized that the equation was for one certain 3-sided polygon..............A triangle.....How can it get more ironic?

"This equation shows of a obtuse triangle can you tell me how I got this measurement Ms.Pines"
Dipper smirked 'Seriously? I've been working with a intellectual legend and you're giving me this?' She picked up the chalk and began writing the problem : 8xY= 6 -y.........= 3cm
"Good now draw the triangle"
Dipper mentally face palmed 'Well at least we defeated him, right?' She took a deep breath, she didn't want another Bipper incident.Dipper began drawing the triangle slowly.One side...The left side...The right side...Good nothing happened.

Well she stands corrected big time.There was a mischievous laugh "AHAHAHA!" the sides of the triangle glowed the world around her stopped with black and white colors."Oh no, Not this again!" she said.A figure came out of the triangle.

"Long Time no see PineTree!"

"Bill..."
