Such a simple portrait, but so, so sad!Mabel's expression is heartbreaking, and though we can't see Dipper's, I bet it is just as melancholy as he hugs his dear sister, comforting her.The fate of the world is at stake, and so is Dipper and Mabel's bond. One is awake in the midst of a crumbling world, and one is knocked asleep, caught in the eye of a storm that is soon to grow nightmarish.Poor Mabel. She's so afraid of the future that she was willing to stop time. But, to be honest, I don't think it was high school or leaving Gravity Falls that broke her heart. I think the thing that hurt her the most was the idea of losing her precious brother. She and Dipper have been together all their lives, and to Mabel, the thought of being away from him as she enters the next stage of her life is both scary and heartbreaking.What is Dipper going to do? How can he and his friends stop Bill now? The journals won't help them here; they have all gone where no book can help now. It's time for Dipper's skills to be put to the ultimate test, one where he and the others might not make it out alive.All the while, I wonder if Dipper dreads that he may never get to hold his sister again. Everything that's going on seems like history repeating itself: Stanford being offered to go to college and leaving Stanley behind; Dipper being offered to stay in Gravity Falls and watch as Mabel has to leave it. Will this end in an equally sad estrangement, or will something even worse happen?Dipper and Mabel have to reach other, that much I believe has to happen. They need to find each other amongst Bill's emerging chaos. What will happen then, well . . . we'll leave that for when the episode premieres.
