So...yeah, it's out there alright.  Finally found it online.  NO SPECIFIC SPOILERS, but the main problem isn't who RJ is, rather it's how they wrote and approached the confrontation.  There are lots of great connections and reasons to think this guy is Red John, in fact I did just that over a month ago, but they don't take ANY time to explain it at all.   Not a single moment to say - of course this is RJ, and here's ABC reasons that led me to that conclusion.   If someone had ONLY watched this season then this episode would be fulfilling, but it pretty much ignores and doesn't answer anything before this immediate arc.  Truly disappointing approach.  You won't hate it, you'll just feel...meh.   They seemed to have lost their passion for RJ along the way and just decided to wrap it up.   

I can say that all those people claiming it's online are correct.  It's real, no network would allow production the money to create a false ending with multiple locations involved.   It's 100% legit.  It's also not a true rough cut as there isn't an editor's timer to mark scenes.  It's done.  This is the episode, only with a few minor sound issues and a start timer at beginning.  If you want to see it, check other comments on this site, that's how I found it.  Took about an hour.
