The Gunslinger," Roland awakes from a dream regarding one of the Tarot cards the man in black drew for him in the first book. He finds he’s on a beach and being attacked by what he calls a “Lobstrosity,” a cross between a lobster and a scorpion. The thing bites off fingers from his shooting hand and also his big toe, rendering him unable to shoot the things.
He escapes westward and begins becoming sick from his infected wounds and also because the lobstrosities bite is poisonous. Remembering the three cards he was drawn during his palaver with Walter, the man in black, he comes upon a door in the middle of nowhere marked like one of the cards called “The Prisoner.”
Having found aspirin while in Eddie’s world, Roland begins to heal. They both return to Roland’s Mid-World and walk down the beach.
The third door labeled “The Pusher” reveals a sociopath named Jack Mort. He takes pleasure in killing and injuring strangers. He is responsible for the head trauma to Odetta causing the split personalities, and also the loss of her legs. He is also the man who pushed Jake Chambers into the train that killed him. Roland kills Jack and in doing so, fuses the personalities of Odetta and Detta forming a third personality of Susannah.
