Actually, I really have it narrowed down to Patrick Jane, Kimball Cho, and Wayne Rigsby. For me, it's more of a gut hunch on each of these. As far as Patrick Jane, he always seems to know how the criminal thinks...his past is kind of shady...and he turns his emotions on and off in a rather odd manner -- very similiar to someone with a mental illness like multiple personality disorder. With Agent Cho, he's just so cold -- doesn't seem to connect much with any of his co-workers -- more like he's observing, so he'll know how to throw them off the track. And with Rigsby, he's a bit unstable -- too emotional...like a loose cannon. Like I said, my theories have no solid facts, they're all just a gut hunch...call it women's intuition. My husband says I'm way off base...he thinks it's the head guy from the church/cult.
