Everett Knox

The  is a minor character in Red Dead Redemption.

Background
Nothing is known about the doctor's background, except he runs the Doctor's Office at MacFarlane's Ranch, and appears to be the town's resident doctor. The extent of his medical credentials are unknown.

Red Dead Redemption
The player can purchase supplies (such as medicine and snake oil) from his office, as well as sell various supplies and materials to him. His office is in a small one-room building near the campfire where the ranch workers and residents congregate at night. There is one bed in it, and sometimes a patient can be found sleeping in it.

Undead Nightmare
During Undead Nightmare, the doctor appears to abandon his office and the ranch, and instead can be found across New Austin. He can be found assisting in the defence of Armadillo, where is usually stationed on either the balcony above the Gunsmith or on the roof of the freight station. He also appears to manage the Missing Persons task at Fort Mercer, giving Marston his reward and the congratulations of the missing person's loved ones for turning them in. He is also the protagonist in a random encounter that can be found throughout New Austin. He will have set up a temporary research camp in the field, with a machine gun installation for defence. He will be conducting research and experiments on the Undead in the hope of finding a breakthrough. He will request Marston bring him bound Undead for him to conduct his experiments on. Initially he will only ask for one, but later will ask for two (he will say that research requires consistency in order to justify this added request).

Trivia

 * He is the only unnamed doctor in the game.
 * He is often confused with Orison Pratt; they are differentiated by slight differences in clothing, although they both wear suits.
 * In addition to Orison Pratt, he seems to share facial features with Dewey Greenwood, Edgar Critchley, Charlie Bengle, Gilroy Massey and Carnelious Wolfe.
 * After bringing in a missing person to Fort Mercer, the doctor will sometimes take out his gun and begin shouting out threats at some nonexistent undead.
 * During the Undead Nightmare random encounter, the player can sometimes loot the chest at the doctor's camp without prompting him to attack.
 * While armed and willing to fight the Undead (even going out in the field to conduct experiments), in the main game he will run away from confrontations and will not pull out a weapon under any circumstances.
