I've watched a ton of old episodes the past few days...whomever posted that Red John hasn't actually killed anyone for most of the show - I AGREE with you. I think Rj killed the people at the barn, Patrick's family, Eileen, Sophie Miller, and Brett Partridge. That's it. I think tyger, tyger staged a great deal of the Rj killings for TWO reasons: 1 - Bertram and Minelli recognize the value in having Patrick on the team, keeping him after RJ is paramount to him staying at CBI. 2 - Some of those RJ murders were covers for tyger, tyger crimes. This leads to why "RJ chose to kill Partridge first" as Heller said. Partridge staged the crimes and crime scenes for Tyger, tyger. I believe RJ loathed him, was insulted by his inclusion on the list, hated that he made mistakes at certain crime scenes and most importantly, by killing Partridge RJ took away a valuable part of tyger, tyger and made the organization much weaker. I think Partridge was accurate when he said "Red John has been laying low for years." He knows this bc he has been the one staging the killings.RJ recites tyger, tyger when he saves to Patrick as his first attempt to push Patrick towards Bertram (who loves William Blake) and the organization that his been blaming him. Tyger, tyger was started by Minelli. Minelli resigns bc the Bosco team murder has put the spotlight directly on the team and he knows or is told this will unveil tyger, tyger.
