OK a new obvious clue that we should all say, "why didn't we pick up this clue sooner."

 post this reluctantly. Trust me, I am so sure Bertram is not RJ (RJ would never plan ahead to have fake passports since he wouldnt beleive hed ever need to escape or be caught), butt.... A clue in ep 7 when Lisbon and Jane here that Bertram's aunt has a place at "Citrus Heights" 

Sadly this ties in well with the early (I believe it was a reading Jane did on RJ) comments about living with a family member with a citrus tree in the yard... to eerie to no be a clue..
Weird..

Don't kill the messenger. I still do not believe Bertam is RJ..no way
