It would be epic if the next two episodes played out like this.

In the press conference Jane tells the media that himself and the CBI have concluded that FBI agent Reede Smith is the Red John killer. Jane convinces everyone, including Lisbon and the real RJ, that its the truth and the media and everyone hunt down Smith, who happens to be killed before he can be taken into custody. As far as everyone is concerned Red John is Smith.

This is what will draw Red John out of hiding and into confronting Jane, he was prepared to run away and start a new life but he can't bare the thorough that someone else will get credit for his work. So he reveals himself to Jane.

Jane then kills him, but as he is dying Jane tells RJ that all the work he did will now be credited to a fat sloppy FBI agent. This is Jane victory, not only has he killed RJ but he's humiliated him as well.

Cheers
