To be honest I'm none the bloody wiser after last weeks episode. If there is a secret society which seems to be rife within law enforcement we are assuming of the CBI at least Lisbon, Cho, Rigsby and Van Pelt are clean. Stands to reason if the Red John case was being looked after by a group of clean cops RJ would want to be close not only watching what they know but also getting his jollies off watching them fail.
Surely in order to be involved or rather control something so unwieldy he would need to command respect amongst law enforcement. Potential peers perhaps?
Ah well. Best I can come up with.
