Price Whatley is former NYPD homicide detective. He's pragmatic and cynical, especially following the death of wife. This has turned Price into damaged soul, full of grief and guilt.
Working alongside Kate, he often questions her methods.
Price: I guess sometimes evil is just evil. I'll say this, I would have never believed what just happened it I hadn't seen it with my own eyes.
Kate: The greater the doubt, the greater the awakening.
Price: Wow, that's pretty profound for being up all night.
Kate: It's Einstein; I saw it on a bumper sticker once.
Price: It must be hard being so damn right all the time.
Kate: It is a burden, but I've lived with it.
Price: Just so you know, I still think you're crazy.
