I put myself believing that Brett Patridge is Red john. It coundn't be any obvious. Bruno Heller said that it is important that Patridge died at the first episode of the season. Many people have been expecting him before that and so does patrick. Self elimination had to be made to clear those assumption or else it would get too easy. And his death isn't even investigated and when lisbon got pulled and faints, red john draw on her face, where the f is brett patridge? Its really confusing but still i expect brett patridge to be red john.
