Okay. We all know the poem that Red John recites to Patrick in the Finale of season 2. It's a part from the poem "The Tyger" by William Blake. I was just re-watching Episode 16 of season 3. And Gale makes a reference that goes as, "When thy little heart doth wake, Then the dreadful night shall break.", which is a part of the poem "Cradle Song" also by William Blake. He also says that he likes the poem. So maybe the appreciation that Red John and Gale Bertram share for William Blake is an indication as to who he really is?
