Looking more at Rosalind as Red John, so many things point to her in 1.23. Jane and Lisbon first meet Rosalind on her doorstep and Jane says he is looking for Roy Tagliaferro. He says "We believe he could be a serial murderer named Red John." Then Rosalind says "No. Thats absurd" and gives a very suspicious smile. At that point she knew she had Jane and Lisbon on the hook and could sell Tagliaferro to them any way she wanted. She later runs into her house, presumably to escape the 2 CBI agents at her door, so she runs to her upstairs room as if that room is her safe haven. It happens to be the room with the smiley face on the wall and she lead Jane right to it to show him.
As is that wasn't enough, the very next words out of her mouth after Patrick sees the face, are "I'm blind, but I'm not blind." Everything in that scene is set up so that Patrick would be completely misdirected when it is revealed that Rosalind is Red John.
A sidetrack from the evidence for Rosalind over to the evidence that Jane has on Red John.
-just under 6 feet tall
-short straight hair
-gentle voice
-not muscular, not soft
All of these characteristics are being used to pin down people on Jane's list of 7, but all of them are based on what Rosalind told Jane.
*A quick note also on how the smiley face is drawn with closed eyes*
-and Kudos to the theory showing that Rosalind slipped Fur Elise into their conversation and smiled after saying it.
