Excuse me, I don't speak English! I find  incomprehensible that the "favorite" to be Red John is Partridge. He doesn't have the characteristic attributed to Red John. No money ( is a simple forensic) or  attractiveness (RJ  seduce beautiful women as Lorelei and her sister) or charisma,he seems the typical freak of classe.You can say that he's acting but characters as Minnelli, Mashburn, Winter or even Mars fit better.
