When PJ & Bertram first met in 03x01 they shook hands on camera and
Bertram called him 'boy wonder' which is kind of weird because how
should he know about Janes nickname from the past.
Also Jane talks about having a bad feeling when it comes to Gale Bertram.
I
don't really know why but Bertram has always been making me feel like
he is suspiciously unsuspicious. I really like the idea of him being RJ
because at least the season 4 finale with him giving the important
'rope' hint would make sense.
Let me know what you think about my opinion :)
