The time had come, it was the time that the twins came back to the Falls. They arrived at the Mystery Shack and were greeted by both of their gruncles and had their friends that they had made that first summer they visited come and celebrate their return. The party was fun and all went well until one stormy day two weeks later. That day Dipper said he was going out he had the biggest smile on his face because he was going to tell his true feelings to some lucky girl.
But he never returned.
Mabel and Gruncle Ford went out and asked every creature that they could find but had no luck on locating Dipper. Eventually Mabel gave up and stayed in her room for the rest of the month only coming down for food. Then one day while Mable was crying her eyes out a sound of ripping was heard. She looked up to see a portal in her room and soon a figure spilled out and laid out on the floor unconscious. She looked him over and noticed that he looked like her brother, at least to her he did. She put the boy on the bed that sat across from hers and then found herself falling asleep next to the strange boy.
