Central Casting (a.k.a NPC ideas)

[Wolf sword]

Amy Smith, Banker.
Amy thought she would be running this town, not the fools who are now in charge. She has the "right skills" to run this place, well she acts like it at lease.
Twists
1) she and her side is just one of 2 (or more) sides fighting for control of the town. See the movie "A fistful of dollars" or "Yojimbo"

Dr. Dave Dovack DDS
The good doctor is a dentist. "Have bad tooth will pull" He is traveling in the same convoy as the PC.
Twists
1) He is not a dentist, he just likes putting people through pain.
2) He is after the same thing as the PC, if he catches one of them well you did see that part of the movie "the marathon man" right?
