I basically have 3 questions for the people who are more observant than I am and then I'll give my thoughts on who RJ is.

1. I think Lorelei mentioned it in the video, and I am wondering, how exactly can RJ know that Lorelei told PJ about the hand shake?

//I don't think she told RJ, because it was a "mistake" in the first place, she said it without thinking, so what? Can we say that she specifically realized such a small detail and even told RJ about it? Also, he was mad about it. Given that he probably knew before he caught Lorelei. In order for him to be mad, he would need something solid to make him believe that PJ will actually use that to narrow down a list or something.

2. How come all of RJ associates suicide, are too loyal to him, and would do anything for him? I don't understand, they remind me of spies who die for their country or something. How can one man have so much influence? 

//Who can have so much influence, power, information, computer skills, and unlimited $$ at the same time? To be honest it only sounds like a "religion" in a sense and it's branches with people in all these places. Visualize has to be definitely connected RJ. The only man who can probably do everything above is Stiles, but he is too old in a sense.

3. What exactly is the connection between the victims of RJ? How do we define him as a serial killer?

Most of his victims are people who pissed him off or something, or people who he killed to make PJ mad. Besides that, how are the victims connected? What does he go for?

//I know he is "famous" for killing some women or something, but I don't recall ever in the series of someone mentioning a pattern or something b/t the victims. It is interesting to me that the only similarity is the setting and the smiling face. I want to know if there are certain victims that he kills.

This is the reason I chose Brett Partridge for now:

He was there all along, and he is the only one from the list that sounds like RJ material. Of course he has a lot of help, and I believe he has someone inside PJs team. Also, all of the 7 suspects are connected to him as well.

The main reason I wrote this is just to see your comments about the questions I have.
