Johnson Nash

 is a Primm citizen in 2281.

Background
Nash is an elderly man living in the town of Primm. At first you can find him at the casino, where he and the rest of Primm's inhabitants fled after the Powder Gangers killed the Sheriff and taken the deputy hostage in the Bison Steve hotel.

After you restored order by finishing the quest My Kind of Town, he and his wife return to their home at the Mojave Express Building, where he also appears to be a trader. If you choose Meyers as the new sheriff, completion will also result in a discount on prices in the Mojave Express shop. If you chose to let NCR control Primm, Nash will cite NCR's taxes as a reason to increase the price of his goods.

Quests

 * ED-E My Love: You can find the robot named ED-E in Johnson's home in Primm. He says the robot is all yours, if you can fix him.
 * They Went That-a-Way: Johnson Nash is the man who tells the Courier what his delivery was and all the details behind it. He directs the player to Deputy Beagle to learn more on where the attackers left after shooting the Courier. The Courier was also supposed to give the payment for delivering the platinum chip and the NCR war documents from the New Vegas Strip to him.
 * My Kind of Town: Johnson will give the Courier suggestions on possible sheriffs of Primm and his opinions on them.

Appearances
appears in Fallout: New Vegas.

Bugs
He may be attacked by gekos
 * Nash may not go into his shop after helping Primm gain law causing him to never be able to trade with you. This may be due to repairing ED-E before restoring law to Primm. One solution is to fire and rehire ED-E while in Nash's shop. Another possible solution on the PC is to use the console to Kill and Resurrect Nash.
 * If you attempt to wake Nash up in order to trade with him, he may become a "floating log" as he moves to his stool behind the counter. You will not be able to talk to him until he arrives there, where he starts to sit down as if nothing happened. (screenshot)
 * There is a chance that your system may freeze upon backing out of the purchase screen.
