If you look close in wellsprings you'll see that 3 dudes are exactly the same. Dylan in the back alley, the guy next to the boardgame, and the guy fixing cars at Rustys garage. Not sure if this was done on purpose. It'd be hard to believe that a game like Rage could not have different NPC's.
Also look at their tattoos, all the same. One even says Wellsprings thug lol.
