Ladies and Gentlemen;
Leaked episode was not fake, It was a bug which developers didn't notice. However, If you watched the episode, you had to consider that episode was not properly prepared as expected. Since, you watched episode before its air date. There will be rearrangments for sound,color and a lot of feature to be done.
So, If you didn't feel anything or you had a sense episode was weird, It probably was because of this reason. Sounds, visual techniques etc. have an important effect on human sense.
However, I don't like the idea which Red John is Mccallister, too. They didn't answer many questions. But think about it, think about Jane's side. Mccallister's (aka Red John) only deficiency was to be appreciated. He continuesly asked for Jane about questions that we were wondering. On the other hand, Jane ignored his requests. He simply said that he didn't care. If he followed the answers, he could be hurted and could be manipulated. And the most important thing was that he didn't want to give Red John what he wanted, to be appreciated.
He directly asked him: "Did you feel sorry for killing my wife and daughter?" Patrick made him sorry.
He directly asked him: "Are you afraid of death?" Patrick confirmed he was afraid of death.
And happy ending. He executed his punishment in return for revenge.
The episode was not perfect but it was not also the worst episode.
