Primm Slim is a guard robot, historian, and caretaker for the Vikki and Vance Casino. Primm Slim is also a huge source of information for the Courier and will speak at great lengths about Primm, Vikki, Vance, and the casino.
Yahoo! I ain't had a chance to tell their tale in a mess of years. First things first: any bosh you've heard about Vikki and Vance being copycats ain't nothing but ill-tempered slander. Fact is, they begun their crime spree two days before Bonnie and Clyde robbed their first bank - so who was copying who. Now true, Vikki and Vance didn't exactly cut a wide swath of murder and bank robbery across the central U.S., like Bonnie and Clyde did. It was more like a narrow swath of shoplifting, check-cashing fraud, and gas pump driveoffs - but crime is crime! They drove reckless, too. Having lived by the gun - well, Vance owned one, anyway - it was only fitting that the duo of desperados would die by the gun. Perhaps it was fate itself that accidentally drove them into a crossfire between police and a gang of bank robbers in Plano, Texas. Or maybe they just didn't notice until it was too late. It's been said that Vikki would have tried to cash a bad check in that bank, had she lived. We'll never know for sure. All we know is that the crossfire tore the car and both occupants to pieces, and the police issued an official apology. You can put your eyes on the genuine Death Car just over yonder, and there's Vance's machine gun in the case next to it!
After taking Vance's 9mm SMG, he will say "Always good to see you, pardner! Anything I can help you with?", but he won't initiate conversation. If this occurs before a sheriff is chosen by the player, it may remove Primm Slim as a candidate.
