Hey everybody 

Lets now just think logically, we know that Partridge and Bob Kirkland are dead so they are out.
Brett Stiles and Gael Bertrum are too high profile to go to Sophie Miller with a fake name, so they are out too.
Three are left which are Smith, Haffner and McAllister.
Reede Smith is one of the tyger tyger also he doesn't fit the description and when he killed Bob Kirkland he didn't kill him with rj's move so I think he is also out.
Now two are left. We all know that there is sth suspicious about McAllister what I think he is with the tyger tyger group but what is strange is that the "young man" looks really like him and also like haffner because he has the same color of haffner's eyes.
Haffner on the other side we dont know a lot about him, only that he calls Lisbon by her first name and thats what rj does also he is a member of visualize and I guess he was at the barn when it all started.

So I would go with haffner IF rj was on the list.

Another thing that Bob Kirkland appears on episode 8 that would be his twin i ont think that these are flashbacks and it also would explain why he would ask Lennon who was in the hospital if he knew him then kill him, he is with rj.

One last theory is about why they (red john associates assuming partridge was with them) say tyger tyger when they die my opinion is that they are hypnotized by rj, like why would someone say tyger tyger when they are dying?! Only if he was hypnotized.
Thats what I think 

And Peace
