Yet Another Summer

The weather is hot and dry when Mabel and Dipper arrive at Gravity Falls in early summer. These vacation were supposed to be peaceful, as were the memories to later take home for another year of work. How long it's been since that summer? Seems like really long, the grunkles have aged strangely enough while the kids grown up. So a lot can change.
But now everything will be alright, there can't be anymore mishaps, they are good people, are they not?
So a lot can happen. Not every mystery has an explanation and not every ache can be eased away. Will the twins stick together? Will the family stay strong, as they gave into fight before? Will Dipper trust again those who aren't trustworthy and could he ever be happy?
