I feel as though it must just be me who still slightly expects RJ to be JJ LaRouche. I know he is not on the list of seven suspects and I know Bruno Heller said RJ is one of the seven suspects, but i still hav this slight suspicion of JJ. The reason I slightly expect him to be RJ is because he is very shady. As we have seen in previous episodes, Patrick had a deal surrounding JJ's "secret". We later find out that secret has to do with JJ cutting out somebody's tongue. You have to be very sick minded to cut out somebody's tongue just to shut them up. Also, I feel like JJ has an act going on, like he's really more intelligent than he acts with Patrick. He also works within the CBI and is involved in various investigations. Although this theory doesnt make much sense considering he doesnt fit the description of RJ described by Rosalind. He could be an ally to RJ. W knows?
