Clip: Grunkle Stan Talks ‘Gravity Falls’ Secrets

To whet the appetites of Gravity Falls fans for tonight’s spectacular “cliffhanger” episode on Disney XD, the House of Mouse has released police station interview footage of Stan Pines, a.k.a. Grunkle Stan, discussing the government’s troubling accusations against him.

In the episode, “Not What He Seems” (premiering Monday, March 9 at 8:30 p.m. ET/PT on Disney XD), government agents take Stan into custody, leading Dipper and Mabel to question how much they really know about their good ol’ Grunkle. The misadventure features a special guest voice performance by Nick Offerman of Parks and Recreation as “Agent Powers.”
