Sorry, after reading my rant I forgot to mention that I believe kirklands mother died or killed by him then he went with his father brett stiles to visualize or maybe stiles killed the mother. anyway please just look at the suspect picture of Kirkland and please tell me it doesn't look like the painted face!!!!  Brett Stiles is trying to protect his son, but like most parents you can only do so much and I finally believe that Stiles will kill his son, not jane.  I think he will be there at the end just when Kirkland is going to kill either or both jane and Lisbon and brett discusses the trial and tribulations of Kirklands wrong doings based on his mothers death and then just before he kills them, stiles kills Kirkland.  show over, everyone happy :)
