When the gay Dr. Micah Newton is found murdered in a golf club with one hit on the head by a club, Lisbon and Patrick investigate the crime scene. Lisbon is interrupted by LaRoche and she makes a comment to him before learning that he is replacing Hightower. He immediately replaces Lisbon by Cho that reluctantly accepts the new position. Meanwhile, Lisbon and Patrick interview Newton's assistant Francine Trent and learn that he was in charge of a transplant program. His position was immediately replaced by Dr. Evan Quick, who change the politics in the hospital aiming higher profit. Among the patients, there is the Russian mobster "Siberia" that has privileges while others stay in the transplant list. Patrick stays with the nurses and observes the treatment spent to the patients to find the killer.
"Bloodstream" is a good episode of "The Mentalist", with Cho performing Lisbon's duties. His character is more convincing in Lisbon's position if this show was serious. However, the intent of this show is to entertain with funny scenes; therefore, she is perfect in her role, knowing how Patrick Jane is important and how to deal with him. My vote is eight.
Title (Brazil): "Bloodstream"
