call me crazy but I think brett partridge is RJ.
just a gut feeling on the man
ask yourself this
1) how does RJ manage to get so many details from the CBI
2) how doe RJ manage to sneak in and disappear into the CBI
3) how does RJ know all the spots where security cams can pick him?
he seems the only one to match the face of the mask, the only one to be smart enough to know the poem of tiger tiger, and the only one charming enough to get the ladies...
I can safely rule out that Jane isn't RJ due to the fact that he has no motive and was on live TV while the murder was being committed
(this is just a hunch so please don't say that all this is flawed, because I already know it is..like I said before its only a hunch)
