The other possibility we're not engaging is that the tatoos are really not RJ. One of the 3 with the tatoos could have used that to frame RJ. Maybe they're bad people involved in some special club that takes matters into their own hands. Maybe we're down to 2 people. Stiles and Haffner. Of all the 5 left, there's only two who could be anyway. It's either Brett or Bertram. They're the only two that make sense from a power sense, personality, etc. The other 3 is just stupid. They're not bigger than life type people. It would be so disappointing for one of the other 3 to be it. Are they corrupt and sinister, sure. Could they be aiding and abbetting, sure. Are they RJ, no. I still have my money on Stiles. Although the I'm going to die thing could be true or subterfuge. So who knows? I'm not convinced they're not it until they're dead.
