Spoiler....



Bertram did state that he was just a foot soldier and not ONE of the top brass so maybe there are multiple Red Johns or other colorful bad guys,  Orange Julius, Blue Jean, etc.  
Also maybe Red John lets his minions do all the dirty work and he just somehow mesmerizes them into doing his bidding because he is a "wuss".  

The 911 call was an incredibly laughable moment.  I thought that when he made that call I would surely hear him say, "Tiger, tiger."   BUT no he calls 911?....Help I was shot but worse than that I was attacked by a pigeon and now there are a bunch of ducks in a pond near me. A man is sitting on top of me now and I can't even reach into my pocket to get my Xanax. 

I'm still hoping that the episode was a ruse.

Pigeon, pigeon
With small beady eyes.
Watch out RJ
It's your surprise.
