"Tyger Tyger, burning bright, 
In the forests of the night;
What immortal hand or eye,
Could frame thy fearful symmetry?"

Patrick could be suffering from dissociative identity disorder, or simply having a split personality. The last line of the stanza "fearful symmetry", symmetry suggesting a reflection of Jane, fearful is his other side. That could explain why Red John was always a step ahead of Jane, and why Jane couldn't outsmart Red John. If he's as smart as a consultant he'll be even smarter as a serial killer. So that's why only he can catch Red John. When they meet face to face Jane will probably be looking into a mirror.
