It was tome for Codes and Ciphers class. Her real name being Obscurial Cipher, it was pretty obvious that she would excel in this subject. She needed to get closer to Dipper, so she sat with him in this class, too.
"Are you seriously sitting next to me again?" Dipper was getting very annoyed by her presence.
"You look really sad, and I'm a generally optimistic and happy person, and I want to help you out," Obscurial tried to help.
"It's private business, why are you so nosy about everything? Just go away. I don't want sympathy," Dipper's face was starting to get really red.
"I'm not giving you sympathy, I'm just trying to be empathetic. I want to help you, not make you feel worse," she tried to get a point across to him.
"Well, it would make me feel better if you just went away. Please, I like to be alone," Dipper responded, frustrated.
"Suit yourself. Have fun with no help." Obscurial was done. Tonight she would invade his mind, as Obscurial though, not Penny. She walked over and went up to Lilith, the girl who spoke earlier.
"Is this seat taken?" Obscurial asked. It would be really weird if she just sat down.
"No, not at all! Please sit here. If you don't remember, I'm Lilith." She was very pretty, with light brown hair, piercing ocean blue eyes, and a galaxy of freckles separating her eyes and nose.
"I'm Penny. Would you like to be acquaintances?" Obscurial sounded really awkward when she said it. She's not used to using human language, but she knows most words in the human language, English. She also. Learned a few others she couldn't remember the names of. Her native tongue, though, is Nightmarish.
"Ummmm… you mean friends, right? I mean, acquaintances sounds, well, like someone you have only met and don't want to get close to. You're new, so you need to make friends to survive. So, friends?" Lilith told Obscurial. She was very confused about this new word, friends, but she went with it.
"Sure! So, what do we do in this class? This should be pretty easy, right?" Obscurial knew it was going to be simple, but she wanted to know what it was like from the view of a person. An actual human being.
"Oh, it is so hard! All the codes you have to decipher are extremely complicated. Hopefully you can catch on."
"Oh, I'm actually quite the code expert. I'll be able to figure this class out pretty easily," Obscurial was sure.
"Just so you know, the teacher is so mean. He doesn't really like any of the students. If you're good though, he might like you," Lilith explained. Just as she finished, the teacher walked in. His skin was very pale, and he looked bald.
"What's his name? I want to get on his good side and address him by name," Obscurial asked.
"Oh, it's Mr. Abosco. I hope you can get on his good side." Obscurial thought the name sounded familiar, but couldn't put her finger on it.
Mr. Abosco looked out into his pool of students. He recognized a new face. "Hey, are you Penny Maze?"
"Yes sir." She hoped the sir would be enough for him to like her, but little did she know, that he already did.
It was a skill that Obscurial hadn't learned yet, identifying creatures by the look in their eyes. She just knew what humans looked like. Mr. Abosco could already tell that she was a demon, because deep inside the pupil, he could see a little pyramid.
How Abasco longed to get up and hug his child, who probably didn't even remember him. He could guess why she was here. Bill's revenge. He should have never trusted Cipher.
The class was a breeze to Obscurial, to no surprise of Abasco, but a lot of shock from her classmates. The bell rang, indicating the end of a long day, and some relaxation. On the way out, Obscurial ran into Mabel.
"Hey, I saw you walking to school, so do you want to walk back together?" Mabel asked.
"Sure, I guess. It would be nice to have some company," Obscurial supposed. So she walked outside the school with Mabel. Then Dipper came running up.
"Ugh, is she coming?" Dipper was very upset. He grabbed onto the sided of his hat.
"Come on, Dip-Dip! She's new to the school and needs a friend. Give her dome company," Mabel tried to convince her brother. Most of the walk was silent. Obscurial was sick of it.
"Hey, Pine-Tree, I like your hat!" The twins suddenly froze.
"Where did you get that name?" questioned Dipper in a threatening voice. Then it hit her.
"Oh! I just thought of your last name, and came up with Pine-Tree. It suits you well, you should go by it more often."
"No," he answered, very blunt. She guessed her father had called him that enough times that he got sick of it. No one else said anything until Obscurial got home.
She had dinner. Obscurial learned that you were supposed to put pasta in boiling water first. It tasted much better after that. Then she waited until midnight, when she would invade his mind to see what he was sad about.
She chanted an ancient chant and found herself morphing into her true form. A mass of darkness, hence her name. She arrived at a mansion, which was presumably Dipper's house, but it had large wooden letters that read "Mystery Shack" on top. Obscurial could see a Bill Cipher symbol on the side of the house.
Inside, there was a hallway, which split into a ton of other rooms. She had no idea where to go. Then she saw one hallway with a black and white photograph, which had hearts around it. The person in it had the same hat that Dipper had on. It was labeled "Wendy"
As Obscurial walked through the Wendy hallway, she could tell that he liked her a lot. At a couple of the memories she looked through, Dipper wrote love letters, went to the fair, and just hung out with her a lot. Wendy looked a couple years older than Dipper though. There was one where he confessed his feelings and got rejected, poor guy.
One of the memorable ones was when Wendy switched hats with Dipper, which explained why he was wearing it. There was nothing that had anything about him being sad, except for the rejection, which was three years ago.
Then he came across it. In the mail, there was a letter addressed from Gravity Falls. That's where he must have met Wendy. It read,
"To my Dawg Dipper,
This is Soos speaking. I have some really, really, really, really awful news that you're going to hate, Dawg, but we all had to face it. I'm just scared it might come as a bigger shock to you. Wendy's dead, Dawg. She was climbing a tree with an axe in her hands, slipped, and fell. We did the best we could to get some rad doctors here in time, but the axe fell right into her head. I took this hat to mail to you, Dawg. Remember your huge crush on Wendy? That was a fun summer. Please don't be too sad. I mean, it's okay to be sad, but don't become a different Dippster because of this.
Stay cool Dawg,
Soos"
It all made sense now. The person he loved died. Even if she didn't like him back, they were still really amazing acquaintances, or that other word Lilith used, friends. Obscurial just hopes he can recover from this, so that the plan will work.
