"Red John doesn't make mistakes. Red John doesn't leave clues."
The whole PI fiasco was full of mistakes.
S2e2 Just how messed up is Lisbon? How did she catch the Red John case in the first place (before raggedy Jane strolled in).
Her t-shirt is fairly short sleeved, and I don't see dots.
She has the sports jersey #17 on her wall.
The jersey she wears is 99.
She always wears a gold cross.
