Rebecca would probably make fast friends with Smoker if he shared those cigars of his. XD She started out with switchblades in her delinquent youth, but she probably carried that dual-wielding over to guns while a soldier. But she would've had a marked affinity for small blades despite the unconscious unease that something was wrong with that.

Also, I wouldn't be surprised if Smoker had to bail her out of a couple of barroom confrontations that she probably started herself or was otherwise the cause of. :|b
