"I should have gone on that quest, not you!" Dipper shouted at his twin.
"It's not my fault!" Mabel cried in response.
The Pines twins had been, fighting all day. Dipper had been jealous of Mabel ever since Great Uncle Ford had let Mabel go on the exciting quest of obtaining unicorn hair to protect the Mystery Shack, while Dipper had been scarred for life when he found out about Ford and Bill, and when he thought Ford had been possessed. Mabel could tell that this was how he was feeling. She considered herself a natural empath. And still...
"At least you got to spend time with Great Uncle Ford! He never wants to hang out with me. He's always doing nerdy or paranormal things with you!"
Dipper could see that Mabel was tearing up a bit, but he didn't care. All his life, he had been mocked by his sister for his "nerdy" interests and fascination with the paranormal. No amount of apologizing would heal his inner wounds.
"Well, if I had been trusted to go on an epic quest to protect our family, I would've been smart enough to see through Celesta-whatever's ruse!"
That did it. Mabel would accept Dipper being jealous of her for dealing with more important and less traumatizing matters, best she would not let Dipper call her dumb.
"That's it!" Mabel grabbed the nearby Journal Number 1 and flipped to a random page. She didn't care what would happen to her brother. They had been growing further apart since they had found out about Grunkle Stan's portal. Her brother didn't matter right now.
"Et iam addicta! Eieci deceptionis in terram, nec hic per vestram!"
Dipper could feel his body disappearing, as if Mabel was erasing him out of existence. He immediately regretted lashing out at her.
"Mabel, wait! You don't know what you're doing! I'm sor-"
And then Dipper was gone.
