What if RJ never had a tattoo on his shoulder? What if RJ told some BA guy to kill that woman in 6x05 and to show the tattoo on purpose? Why would RJ wear a tank top? That doesn't make sence at all. What if RJ knew she would get caught by the CBI while bugging them? Why did he need to bug them in first place? He had his spys all over the country.. These things are mistakes no one would make if he only considers to do something illegal, right? I would never wear something like a tank top or t-shirt if I commit a crime (yeah NSA you're reading right!). There could be things/hints on your arms or something that leads only, and only (!), to you. So why would a genius like RJ, the antagonist that is supposed to be a mistermind like Hanibal Lecter, do such an obvious mistake? That jus doesn't fit at all.
I think RJ planed all of this. It was staged. If RJ doesn't have a tattoo the sentence by PJ "The bomb was a mistake. It was theater. I knew whatever the truth looked like the opposite must be true" gets a whole new meaning. If the list of suspects is correct Haffner and Stiles become number one suspects. They fit in the discritopn that there is/was a (strong) bond between RJ and visualize. Besides if McAllister "died" and comes back, everyone including Partridge could be still alive.
I know we can't give a damn about the clues that Heller gave us, but what if there is more? What if Heller and all the actors want us to belevie that RJ is no more and then bring up a fucking red smiley on the wall in front of the dead bodies of Rigsby and Van Pelt? It would be awesome!
And for last... IF RJ is really dead... it was awful writing and BH sucks!!!
