For one moment, Gravity Falls was peaceful. For one moment, the Pines could relax. But then that moment ended. With the arrival of a mysterious stranger, and a conflict between the Northwests, the Mystery Twins' lives turn upside down. (Begins later on the night of Northwest Mansion Mystery, but here, Not What He Seems does not occur that next day. Rated T just to be safe.)
