Kim Fischer was hired by someone other than the FBI to spy on patrick. We know this to be almost fact.

Wiley is more than just a computer nerd who seems helpful, but i am not sure about him yet.

Its HILARIOUS that Visualize, Styles, or Haffner have not been mentioned yet. They will eventually...
Also, Styles and or Haffner are alive without a doubt in my mind...

Important highly paid actors as those two could not of died off camera. Shows NEVER kill important characters off camera. I am sure it has happened in the past but it is very very RARE.
One of them may be dead most likely Haffner from the gunshot but no way Styles died for no reason off camera . There is hope!
