Ok. If you don't think Partridge is Red John, you think Patrick is going to catch Red John using a plan he makes up on the spot. You're effectively calling Patrick a dumbass, you're saying Red John is psychic and Bruno Heller made up a crappy ending.
Partridge is Red John. "The game's over and I won." That is Jack Plotnick. It was not the guy in the church saying that line. It was Partridge in the park.
