Some revelations were made in "Red Listed".
1) Lorelei Martins is dead. That's because Kirkland was the only man who could fake her death or save her, as he was responsible for her body. But he had no idea about the real list, so Lorelei must be dead.
2) I think this one is the most important. The person, who told Kirkland about Tyger-Tyger, could be RJ. Why? Because of coffee :-) You see, Kirkland brought with him three types of coffee. He explained that he did it for Smith, but that wasn't true. How many types of coffee one can find? More than three. So, Kirkland actually had two appointments in the park. As he left after talking to Smith, Reede must be the second appointment. The person whom Kirkland met before Smith, refused to drink coffee. Why? Because he prefers tea. We know two people who prefer tea. First is PJ, who could have no meeting with Kirkland according to the further developments of the episode. Second is RJ. So who could it be if looking at the list? Not Smith, probably not Bertram. All the others.
3) Now I strongly believe I was right some months age posting this: http://www.whoisredjohn.com/See-a-theory-Red-John/3673
4) Tyger-Tyger... The very first time it was mentioned by RJ. Why? Was he thinking PJ is an insider? Or may be RJ wanted to warn PJ about something? Again I have to remember Todd Johnson. Was he killing good or bad cops? He refused to kill Mars, so it seems Todd wasn't so bad. Later he wanted to see PJ and tell him something only PJ could understand (probably Todd found it safe to talk to PJ, as there was no way him being in Tyger-Tyger). Anyway, it's very-very pleasant that this Tyger-Tyger thing was planned from season two!!!
5) Wish to give some tribute to Bob Kirkland. He was a good guy. You know, the term "red listed' is also used to describe dying species (listed in the Red Book). Tigers are also listed there. I think Bob Kirkland was red listed. RIP. But I hope we'll enjoy some new portion of very charismatic performance by Kevin Corrigan, if he returns as Mike Kirkland. By the way, now PJ has a valuable mean. He may try to find Mike (we know how he looks) and if finding alive, probably try to use the knowledge about his past and direct him against RJ.
Thanks.
