It's not about 666. It's not about Partridge (he is truly dead). The clue in the last scene of the first episode, refers to blood in face of Lisbon. I explain
When I watched the first episode, one thing jumped to my eyes: Red John does not draw the traditional brand in the face of Lisbon. It draws the eye vertically traits, and he does so affectionate, almost caressing his face. This design reminds you not someone else? The Colombina is a character from the commedia dell'arte. The characterization is a common intelligent girl, humorous, always involved in some trouble, in love with Harlequin, and loved in secret by Pierrot.If Lisbon is Columbine, Harlequin and Pierrot who they are? It is obvious that Jane has feelings for her, which are matched in spite of suspense. Red John should have a reason to keep her alive, could be a loving motivation. Red John is possibly in love with Lisbon.My speculation: Who's list is close enough to Lisbon to nurture that relationship? More, which declared them personally care for her?
To strengthen the theory of analogy between the history of Colombia, Harlequin and Pierrot with Lisbon, Jane and Red John, Colombina, in Italian, means "dove", literally one small pigeon. In the room where Teresa met Brett Partridge, had many pigeons.
summarizing:
The clue is that Red John saves feelings for Lisbon! But at the same time I'm afraid to say that Ray Haffner is Red John, because I do not know if any other suspect neither does secretly.
Recalling that Patrick cleans the blood, realizing that too. Theory, which in my opinion is proved when the nurse enters (episode 2) in the room of Lisbon asking any name, just to see if she was awake and monitored. See Patrick's face at that moment! Red John was acting through a lackey, but he was. Ladies and gentlemen, in my opinion, whoever he is Red John, he really cares for her.
