I've been wondering if Patrick is RJ many times, but there is always one thing that makes it impossible.
Could he kill his family? Sure. If he really is that cold-blooded sociopath, he could do it to have an excuse to join CBI and mess with them a little bit. To have fun.
Also RJ is really great in hypnosis (which I think puts Rigsby out of equation) and as we Know Patrick is one of the best.
But why on God's Earth would he (as RJ) rarget as a enemy number one himself??
He is messing with Jane, surely enjoys this whole game between them. What fun would be messing with himself? No fun at all.....
How do you find this theory?
