Mabel frowned, which was completely out of character for the usual happy-go-lucky cheerful and optimistic girl.
Dipper had left without explanation, which was something he never, ever did. He would always tell Mabel when he was off on some epic monster hunt, or Stan would be laughing as he forced Dipper to do something like hammer up signs. If that was the case, Stan would of most definitely told her about it, too, and even he was now acting out of character. The point was, though, whenever Dipper left, they always knew where he went.
But not this time. They had not even the faintest idea of where he was. And whenever he left, he was never gone for more than a few hours. But he had now been gone for several days. She hasn't slept in days, either. Not even a wink. She was too paranoid about her brother and her heart was filled with too much panic and despair. She could tell Stan, nor his new brother, hadn't slept either.
She knew that Dipper was angry and upset, and that he needed time to recover. But he always forgave her in the end. He could never stay mad at her forever. But this time, she was afraid she was wrong. That this would be the permanent end of their relationship. She wished Dipper would hear her out, deep in her heart, she knew she made the right choice for everyone. Without Stanford, the brother of her grunkle who was revealed to be named Stanley, the prophecy to defeat Bill could never be completed.
Unfortunately, the prophecy couldn't be completed without Dipper, either.
Stanley had similar thoughts as Mabel. He had always made fun of Dipper, like that one time Dipper stayed up all night and had dark bags under his eyes, or when he and Mabel teased and mocked him for his height. Or other countless times.
He was guilt-ridden, and he could not explain just how much remorse, a rare emotion for him, he felt. He truly was a horrible uncle. He lied all Summer to both his and Mabel's face, from the journals, from not knowing about the supernatural, and most of all, the portal.
And now, he feared Dipper was gone for good. He did often venture out when he was angry and needed to cool off, but never for long. Now, it had been days, and still no sign of Dipper.
Suddenly, there was a knock at the door. Both Mabel and Stanley sighed pessimistically, wondering what the random person was about to bother them about. Maybe someone finally came to blame them for the gravity anomalies.
But it wasn't. The sight of who it was made their jaws drop, and both of them swore their hearts stopped.
It was Dipper.
Or was it?
