I have decided to make a list of questions that should be explained in the next episode(s):

1. How did Red John knew the list before Jane did?
2. Why did Red John Killed Partridge?
3. Why didn't Red John Killed Teresa?
4. What have happened with Michael Kirkland?
5. Why did kirkland killed a member of the RJ organization at the hospital?
6. What is the RJ connection with visualize?
7. How did Red John survived the bomb?
8. How did he put the bomb in first place?
9. What was that shot heard at the end of episode 6?
10. Who is Bertram calling just after Jane asked him to go to unveil RJ?
11. What does 'He is mar" means?
12. Is RJ the creator/director of the Blake organization?
13. What is up with all the birds long scenes that appeared in all episodes of this season?
14. Why did RJ put a recording device on the CBI office, especially since the Tyger Tyger already have all phones intercepted? 

And there are things that does not add up with the description that we have of RJ and most of the suspect, for example, Reede was kind of bossy at Bertram office to who is supposedly his leader.
