Twin Peaks Season 3: 10 Things That Need To Happen

3. And Who Is Dianne?

The other big enduring mystery of the programme is who the heck is Dianne? Throughout the series one of the many eccentricities of Dale Cooper was his constant audio notes made to an off-screen character, always addressed to her by name and recorded on his hand-held cassette player. There's been speculation ever since the show aired as to who exactly this Diane was, or whether she was even real - after all, we never saw Cooper contacting Diane in any other way, explaining to anybody who she was, or sending off the countless hours of tapes he was presumably recording for her. Things got a little more cleared up with Fire Walk With Me, where we saw Cooper talking to someone called Diane at the FBI headquarters; at least, we saw him addressing someone off-screen as Diane. They never actually showed us what she looked like. So, really, that doesn't explain anything. Does she work at the FBI? Is she somehow related to Cooper? Are they just pals? Are they romantically entangled? What's the deal? She might not even be real, so far as the viewers know. Even the spin-off book The Autobiography Of Dale Cooper didn't clear things up any further. Some fans have theorise that she doesn't even exist at all and is actually Cooper's way of coping with the loss of Caroline, the ex-wife of Windom Earle that he copped off with for a bit before the show started. Then again, when he asks her for earplugs he receives some pretty quickly, so maybe she is real. But when will she actually appear on screen? Hopefully in season three.
