Heller said we would find out why the voice doesn't match any of the suspects. It strikes me that the promo video shows a bald man in the church who sounds like Bosco...so maybe Heller had the actor playing Bosco do the voice just to through us off? Or is it Bosco as a figment of Jane's imagination (maybe referring to his relationship with Lisbon) and the person we see Jane talking to after that in the church is another person? These promos always throw us off. I guess it also sounds like the bald serial killer (Linus) from the premier episode, too, but he was short.
I don't think RJ is Bosco, but it made me choose someone.
