I was watching the season 4 finale the other day and something else that points to bertram came to me...We never recieved any kind of closure on how wainright was obducted by red john/ his accomplices....I believe this is done intentionally....ASK YOURSELF THIS.....Of the 7 suspects....which one of them could possibly isolate wainwright from the cbi and pull him out into a limousine? stiles? no way, Partirdge? are u kidding, Hafner? maybe but probably not, Reede Smith? na, Mcallister? not even a chance, and Kirkland wasnt even around at that point....SO that leaves Bertram......The chi director is probably the only person AT ALL let alone on the list of suspects.... that could have gotten wainright out of the cbi and into his own complany and then tied up and eventually shot....
Its a perfect plan to abduct luther for a couple reasons....
A) hes not going to be able to talk to jane with his mouth ductapted
B) The CBI/FBI will shoot thru the window if RJ and company lose the shootout.....killing wainright instantly
I never really understood why they didnt investigate wainrights abduction more, but now it is all starting to make sense!!!
