There's not much on this episode. We do know that Pacifica discovers the existence of the Department of the Enlightened and attempts to confront them. Dipper tries to stop her, fearing for her safety, but both of them are caught. Pacifica's memories of the night are erased, and she's let go. Dipper is turned over to his great uncle who is not happy with him at all. The next morning, Mabel tries to talk to her brother, who brushes her off coldly.
