Well I have something to say...I was a Partridge fan,I still was until yesterday,he is dead in the corps and from the promo we see a balding looking man appearing to be Red John,also the voice nothing like Partridge. So,I rest my case...Partridge is not Red John
From the promo it is obviously Thomas McAllister.
For all of you thinking Red John is not on the list,I am not sure but I think I heard Patrick saying to Kirkland last night that he havent´t told to a living soul who suspects are...just mentioning it,although I think Red John is on the list,otherwise the list with 7 names would have no sense...we already know the fake list was planted for someone who had intentions to steal information from Jane and that someone turned out to be Kirkland so the list is probably real(there is no reason for 2 lists to be fake).
What I am hoping is going to be revealed is how Red John predicted the 7 names on the list,we already found out how he knew about the "happy memory" and there were some theories even before the start of the sixth season that it was somehow connected to Sophie Miller and it turned out to be true(I read about it on the mentalist board on Imdb and maybe it was mentioned here also,I don´t know).
As far as we know,Jane shortened his list to 7 names by predicting who could physicaly be at all those places where and when murders happened...my guess is that all the suspects from the list except Stiles are somehow connected to the Tyger Tyger organisation and they were at some point at Red John murder sightings doing some cover up and cleaning mess,that would explain how Red John would know the names because those are the people he sent there. It could be I am wrong but I haven´t come up with a better theory so far. What do you think how did Red John know who will be on Patrick´s list?
