I have often wondered who killed Jared Renfrew. If it was RJ surely he'd have left Jane a smiley face? It's a faux pas clue. If RJ is one of the 7 on the list then Bertram or Stiles are the only powerful people we've met who could coerce others. Stiles has the power, charisma, etc, but has he the strength to physically kill? Bertram first called Jane The Boy wonder which was his name when working with Alex Jane. Also quote Blake poem and has sounded like RJ too! Not forgetting he was at the mall with Jane in Strawberries and Cream and was prime suspect as RJ's mole. Instead of being RJ maybe? But he's logical yet too obvious. So who is RJ? Easy. It's Alex Jane!
