I have been said this many of unlikely of this theory but I still will always never change my mind of grace being the partner of Red John. As you know her job when she did get there what she does and how close she is to Lisbon to know how to get the names she did for John who ever he may still be even though we now think he is dead. I have said more to this as of the drawings being of her or her drawings. I can not see it being rigsby I but I do know they do sleep together so she doesn't have the dots and am sure who ever Red John is has no dots but mainly its cause its unlikely the more unlikely you get on something like my comments is the more plausible something is. Its a tv series has to shock you has to have something nothing other then this would do it. If Grace is not a part of it as of some sort of partnership or relationship or family to this or anything of this the show is to plausible. By the way ever see people get married in a police division or even make it ok. so this will always be my theory and its mine cause its not likely and I am glad more and more say its not likely.
