I dont think jane is roy but i think there is much more to the roy story.
For some reason red john wanted jane to meet rosalind and find out the name roy.
I dont trust her or any red head in the show.
Kristina freye is not to be trusted.

Red john could be a group of vigilante women for all we know.
When kristina stood up for red john saying "but patrick you lied about him"
I knew right then she was evil. Who says that?
