Amnesia (BillDip)

Understanding.

Dipper offered his hand to the former dream demon and hoisted him back to his feet with a low apology, that was accepted with a nod as Dipper tugged him into the woods and away from his family with a shout of "Nothing, be back later."

The blonde looked at him in wonder, confused as to what was happening. They came to a stop after about ten minutes, deep into the woods where no one could hear them. Dipper let go of Bills hand and faced him, panting lightly.
"Dipper? What's wrong?"

Dipper caught his breath before looking at the other one sadly. "Look, Bill, if that is you... last time you were here you did some very bad things to a lot of really good people. People here don't trust you, they don't like you. So you're going to have to change your last name at least. So they don't know who you are."

Bill nodded slowly, "But I don't understand, what did I do that was so awful? Why can't I remember anything?"

Dipper smiled sadly and gave Bill a look of sympathy. " We'll figure that out later. And as for what you did, i'd rather not think about it."

Bill hugged himself. "Oh... I see. I'm sorry." He looked off to the side sadly.

"Try not to think about it for now. But you can't mention it to anyone. Don't ask anyone about it, especially not anyone in the Mystery Shack, what were you doing there anyways?"

Bill shrugged, "I... I don't know. I just felt drawn there. It seemed so familiar. You seem so familiar, it's like I've seen you before even though I don't remember anything about you or this place. Dipper?"

"Yeah?"

"Um... what are we going to do now? I don't have anywhere to go."

Dipper paused and thought about it for a moment. "I guess you can stay with me. We'll have to talk to the family about it. I'll have to come up with some sort of story to tell them. I guess we can always just start with we just met and became fast friends and we want to have a sleepover."

Bill stared a moment. "A... Sleep over?  What's that?"

Dipper smiled, "Wow, I've got a lot to teach you, huh?" He felt a little bad for the dream demon, despite having almost been killed by him and permanently traumatized, this Bill seemed like a decent person so far. "It just means that you're going to sleep at my house."

"S-sleep?" Bill's eyebrows furrowed.

"Yeah, you know, you close your eyes and rest."

"Oh. I don't think that I've ever done that."

"I don't imagine you would have needed to. Come on, let's head back." Dipper said, turning and beginning to walk back the direction they had come.

"To the Mystery Shack?" Bill asked, jogging to catch up.

"That's right. My family lives there, Gruncle Stan and Gruncle Ford and my twin sister Mabel. Soos lives there too with his Abuelita, but she's leaving tonight to the old folks home. She'll probably be gone by the time we get back actually."

"Oh, um... what's a gruncle? and what's a twin sister?" Bill asked him, a little embarrassed that he knew so little.

Dipper actually seemed shocked by this but just chuckled, "Gruncle just means great uncle, so he's my dad's, the man that uh... made me, he's made by the same person that made his dad." Bill 'Oh'ed, obviously understanding, "And twin sister means that Mabel looks just like me but a girl, and we were made by the same person at the same time."

"Wow! How did Dad have time for that?" Bill demanded in awe.

Dipper burst out into laughter, "No Bill, his name isn't Dad, it's Mr. Pines."

Bill just squinted, "I don't get it. Why does he have more than one name?"

"Because I call him dad, because that's his relationship to me. Kind of like how Mable is my twin sister but you would just call her Mabel, make sense?" He tried.

"Um... not really, sorry. Everything is just so...  weird."

Dipper snorted, yeah sure, this is weird. Just wait till he saw the Gnomes and various other creatures native to Gravity Falls. The Mystery Shack cam into view, the others had gone inside and it was just about lunch time. "Are you hungry?"

"Hungry?"

"Yeah. Do you want something to eat?"

"I... don't know."

"Okay well come inside and have something anyways. You're in a human body, so you probably need food. Though I have to wonder where you got that body from."

Bill shrugged.

"Knowing you you probably killed someone for it."

Bill looked shocked. "What?" He demanded loudly. "Kill someone? Have I killed people? Like, dead? Dipper-"

"Shh, shut up, they'll hear you. Look we'll talk about it later, okay? Just act normal." Dipper instructed as he pushed open the door to the mystery shack, walking in before Bill.

Stan, Mabel and Ford were all in the kitchen getting ready to have soup and sandwiches, prepared by Mabel. Dipper entered the room and smiled at his family. "Hey guys, this is my friend Bill Jones. Is it cool if he stays over tonight?" Bill waved shyly. "Hello Dippers family."

Mabel hopped up, "Dipper, I didn't know you had friends! and he's so dreamy!"

"Mabel!" Dipper scolded.

"I'm dreamy? I-is that good?" He asked Dipper, instead being answered by Mabel. "Of course it is! Now come have some lunch, are you hungry Bill?" The name still fought her tongue to say, she didn't like it, but this guy was so much nicer than Bill Cipher. And way less pointy!

"Uh, yes? Dipper told me that I should eat something earlier."

"Because you haven't eaten all day. "Dipper jumped in, attempting to save the conversation before Bill gave himself away. "It's not healthy."

Bill nodded and sat where Mabel told him to, Dipper next to him.

"I see no reason why he can't stay." Stan offered. " Just don't make too much noise."

Dipper nodded. "Thanks Gruncle Stan."

"Oh, oh! I'll make him a sweater. What's your favourite colour?" Mabel asked Bill.

"Oh. uh... This one." He pointed to his existing sweater.

"Bright yellow, huh? You're my kind of guy Bill Jones!"
