Twin Peaks:
Agent Cooper - Went on a mass-murdering rampage while being possessed by ‘Bob’. His victims included Agents Rosenfeld and Dennis/Denise, Sarah Palmer, Norma Jennings, Shelley Johnson, Catherine Martell and Lucy the receptionist. Cooper was gunned down by a reluctant Sheriff Truman.
Sheriff Truman - After having to kill his best friend, he lapsed into a long period of alcoholic despair. He was dismissed from his post as Sheriff and attempted suicide, only to be ‘rescued’ by the spirit of Josie Packard who appeared to him in a vision. Truman then went on a vision-quest to root out and defeat ‘Bob’, aided by crazy, one-eyed Nadine (after she’d recovered her memories & stopped obsessing about the drapes). Harry & Nadine fell in love after fighting off ‘Bob’, married and Nadine gave birth to sextuplets whom they named - Desmond, Robert, Arthur, Peter, Edmund and Spencer.
Deputy Andy Brennan - The formerly clumsy goofball deputy became cold & steely after Lucy’s death. He succeeded Truman as the Sheriff, and to everyone’s surprise was extraordinarily capable in the job. His first major incident was to take down a bezerk Leo Johnson, who was stalking Shelley yet again. A grateful Shelley fell in love with Andy and married him. (BTW, Shelley took over the Double R Diner after Norma’s untimely offing.)
Audrey Horne - Like Truman, she was so distrought by Cooper’s possession / death, she descended into a depressive state. Unlike Truman though, she never recovered. She’s a meth-addict, works (barely) at One-Eyed Jacks’ and is disowned and entirely estranged from her born-again father Roger.
Donna Hayward - Had a rocky, on-again / off-again relationship with James Hurley, but eventually realized that he would never get over Laura Palmer. After deciding she couldn’t stand life in Twin Peaks anymore, she packed a suitcase, snuck up to James’ window for one last forelorn look at him, then walked down the road out of town and into the darkness. She’s has been neither seen nor heard of since. (And she was wrong about James. Ironically, he was planning to propose to her, and was much disturbed when Donna simply vanished, and would never get over her. James eventually was killed after crashing his bike after a drunken night at the Roadhouse.)
Log Lady - The willows still whisper to the owls about sadness from beyond the depths of the ocean. The moon chews bubblegum while ten silver spoons dance merrily to the tune of a piper of another age…
’Bob’ - The epic battle with Truman & Nadine left him wounded but not defeated. He still lurks in the Black Lodge, is still a presence in the background, and awaits the next opporunity he’ll have to emerge and wreak havoc among the townsfolk of Twin Peaks.
