I can't stop thinking Danny Ruskin is Red John. I've re-watched the episode [S03, E02.] over and over. Each time I'm more convinced its him.
There's a very chilling feel to his last quotes of the episode when he's with Jane at the cemetery.
"Sorry I asked to come.. Who knew a trip to the cemetery would be such, a downer."
And then the way he says; "Guilt is for marks. You know that right?"
He also certainly fits the physical description if Red John. He and Jane are also very, very alike.
