Showtime may be keeping secrets on its Twin Peaks revival, but even the original series managed to hide the famous Diane that Kyle MacLachlan’s Coop seemed to always record messages for. Now, the obscure figure may finally step into the light, as Laura Dern joins the series for a major role.

Take this one with a grain of salt for the moment, as TVLine confirms that Dern has joined Showtime’s Twin Peaks in a “pivotal” role, albeit treating the Diane aspect as a strong theory. “Diane” acted as Cooper’s offscreen secretary during the series, the agent frequently addressing her in his tape-recorded notes, though some had theorized the character as a figment of Cooper’s imagination.

For her part, Dern worked with Kyle MacLachlan and David Lynch previously for Blue Velvet, also starring in Lynch’s Wild at Heart and Inland Empire.

David Lynch and Twin Peaks co-creator Mark Frost wrote the scripts, with Lynch confirmed to direct all episodes of the revival series, however many that turns out to be. Twin Peaks composer Angelo Badalamenti and stars Madchen Amick and Dana Ashbrook have all been heavily rumored, along with Sherilyn Fenn, Miguel Ferrer, David Patrick Kelly, Richard Beymer and new additions Jennifer Jason Leigh, Robert Forster, Peter Sarsgaard, Robert Knepper, Amanda Seyfried and Balthazar Getty.

The original Twin Peaks saw Agent Dale Cooper arriving in the titular town to investigate the murder of homecoming queen Laura Palmer, only to find the mystery ran far deeper than he could ever expect, with a touch of the supernatural. The new iteration will pick up 25 years after the Season 2 finale in 1991, which saw MacLachlan’s Agent Cooper in a Black Lodge limbo.

Showtime has yet to set an official Twin Peaks premiere for 2017, but what do we make of the latest addition?
