Stanford sat on his former office inside the mystery shack, right before Soos and Wendy bursted through the door and screamed "Save the Mystery Shack!"
After a moment and cut back to reality, Dipper and Mabel watched in shock at the scene; the office was a mess, Stanley was helping his beaten up brother get up, and Soos and Wendy told the twins the story while ignoring the fact that they looked rather beaten up themselves.
"And that's how we saved the shack from closing for good!"
"Good golly, Stanley, how and why did you get these employees?!"
"Desperate situations require desperate measures."
