UPDATED with details of final episode: Disney XD confirmed the hourlong series finale for Gravity Falls will air Monday, February 15 at 7 PM.

Creator Alex Hirsch announced on social media in November that the series would wrap with Weirdmageddon 3: Take Back The Falls. Hirsch noted at that time that it was his choice to end the series, rather than it being canceled. It wasn’t a matter of ratings: The show’s mid-season premiere in July drew Disney XD’s biggest audience ever for a regular series broadcast in Live+3. In the final episode, Ford discovers Bill’s true motives and then a final confrontation with Bill leads to the Pines family’s ultimate fate and greatest sacrifice.

The animated series, which launched on Disney Channel in June 2012 and moved to Disney XD in August 2014, chronicles twins Dipper (Jason Ritter) and Mabel (Kristen Schaal), who live with Great Uncle Stan in the off-kilter town of Gravity Falls, OR.
