I know some people may find this far fetched - But how many children as Red John killed?
All we know is Charlotte...right?
But what if Charlotte is still alive?
Reason 1: When he used that girl and drew the Red Smiley Face on her hand, that's all he did, he didn't hurt her.
Reason 2: When Jane drank that tea he saw Charlotte and only Charlotte at the age she would be, why not his wife too? Maybe because his wife is dead.
Reason 3: What if that night they were "killed" and he opened the door Red John was there and brained washed Patrick into believing they were both dead - I mean he did brain wash Kristina Frye into believing she was dead.
Reason 4: Maybe when he had that breakdown in the hospital - Charlotte was there too. But his mind believed she was dead.
I mean when he drank the tea he had a vision and he was in a straight jacket and lying on a bed and Charlotte was standing over him.
Was she trying to get him to remember?
Reason 5: Look at the grave stones you'll see there name and only names. Why no date of birth or death?
