The Mentalist ended its season six with a tagline "True love has found a way." If you remember, Bruno Heller said he wrote "Blue Bird" as a series finale. The whole episode was about love and what are you willing to do to show it. The Mentalist 2.0 has been the journey of Jane and Lisbon, a journey to understand who they really are and what they really want. From the very beginning of the episode, Patrick Jane still asks to Cho - and more to himself - if Lisbon is really leaving. He thinks she knows her well and she won't make such a big move... the truth is, Jane's dening the fact Lisbon is leaving because he'afraid to come face to face with his feelings for her. Despite this, Jane cleverly manages to solve a crime involving young students and come back to the FBI building, ready for another case. Lisbon is forced to postpone her departure when a cold case brings her and Jane to Miami: there's a letter written by the killer and they need to know who wrote it. As the two are the guests in the Blue Bird Inn, Jane is clearly happy to spend some quite time with her "more than friend" Teresa. Just to remind her how great are those two when they work together, a long walk to the beach is the key to solve the cold case. Lisbon is happy she's decrypted the mysterious code on the letter; it's clear she learned from her mastermind (Jane) how a serial killer's mind works.
"You don't give a damn about what I want, or need. I am just a convenience for you. You use me. It's all about you. You used a woman's murder Jane, you basically dug her corpse up for this crap! you're so twisted in your own dishonesty you have no idea how to act like a decent human being. No idea."
With those words, Lisbon put Jane in the condition of thinking about who he really is: he's always being a con man, acting like a clown in kinda way, pretending it's ok to stage a play just to solve a murder case. Lisbon feels used: remember in episode 6.09 he made her come in Austin to join the FBI, otherwise he wouldn't have accepted Abbott's condition to work. That's the breaking point when Lisbon decided to call a cab, go to the airport and call Pike to tell him she accepted her proposal - Pike's reaction was awful... what kind of man reacts like that like if he just won a football game? Anything but romantic. Jane thinks he's lost Lisbon forever, until he gets a visit from two lovers - from the cold case - who make Jane opens his eyes: "I was a coward- blind, stupid coward. I was so filled with fear and self-hatred that I destroyed the best thing that ever happened to me. By the time I realized my mistake, it was too late. She was gone." There comes the realization everyone was waiting for - but it can't be easy, right? When the two women Fischer and Cho had interviewed before for the case, Jane does everything he can to manage the situation, because the first rule is: keep calm and text "SOZ" to your boss. Abbott and Cho can arrest the women and release the men, and let Jane go to the airport to stop Lisbon. Poor Cho, he seems to be the voice of that fandom who doesn't want Jane and Lisbon to be together. "They're like brother and sister." But anyone is free to think what they want, right?
