3rd person POV

Mabel was in their room thinking about what her next "Mabel's guide to" is gonna be, when she heard a knock on the front door. She looked out the window and saw that Dipper had come back, with someone.

She exited the room and speed walked down the stairs, Stan already opened the door.

"Dipper? Who is that guy?" Mabel asked, looking at Dipper's companion

"This is Bill, and he wants to stay with us" the brown haired boy replied.

"Wait, did you just say Bill?! As in Bill Cipher?! The demon?!" Mabel freaked out when Dipper nodded.

"Oh no, kid, that demon is not welcome here at the shack!" Stan pointed at the door

"Sorry, Fez, Pinetree made a deal with me, and he can't break it" Bill spoke up

Stan let out a sigh and approached Dipper and whispered something into his ear. "Kid, if Ford sees him, he's a goner. So if I were you, I'd hide that Dorito"

After that warning, Dipper guided Bill upstairs. "So, where are you gonna sleep?"

Instead of answering Dipper's question, he flew into the twins' room, the brown haired boy ran after him. "Bill! Don't you dare!" Inside, he found the dreamon, reading his diary.

Dipper's POV

That used-to-be-Dorito started flipping through the pages of my diary- uh, I mean, journal.

I tried to snatch it back, but that just made him float up higher, high enough for me not to reach.

He stopped at one page and started reading it aloud.

"June 4, (2 years ago), today, I was at our home, looking outside the window, when I saw some little kids flying some kites in the air, and one of the kites was a yellow triangle. At that moment, I remembered a certain floating Dorito back at Gravity Falls, Bill Cipher. Sure he was a jerk, but there was something about him that made me, well, not hate him as much"

My jaw dropped. Why of all the pages, he had to read that one?!?!?! Ugh! I feel so stupid! I feel like my face was heating up, so I buried my head in my shirt in embarrassment. 

I looked up at Bill, his face was a little red.
