I honestly don't trust the list.And other thing RJ should be one man army, evil genius and manipulator with devoted minions. All of his friends show great admiration for him, Rebecca talk about his mission of enlightement and that it has nothing to do with Tiger Tiger gang.
If it was that silly group Jane would discover that in an month, not in 5 years.
Let face it, only if they were all master manipulators like Jane they could get away for so long.If RJ is a group there is lot of weak links and they would break easily.
So as I said one person modern Professor Moriarty with qualities of PJ,Walter Mashburn and Brett Stiles.

I believe now Todd Johnson was killing members of Tiger club and if he knew RJ, they were on a same mission.They say to Jane that there is a bigger picture and explanation for everything.
But if the list is true then Haffner is the only one that fits.

MCalister looks even emphatic for Jane or he is RJ.

I really hope Heller will finish this story in the right way,RJ as a one mastermind vs PJ. battle of minds not man vs group.
