Right from the start, I expected the last season of this show will be like this: 

The first half of the season will be about Jane getting closer to RJ's identity and eventually learning who he is. 
The second half of the season will be about Jane and RJ trying to kill each other, playing well-planned mind games and RJ will be killed in the series finale. 

I was a bit puzzled when things didn't occur the way I expected. But human race is intelligent. Nobody makes the same mistake three times. First, McAllister can be seen as lying dead on the poster of the 8th episode. Second, McAllister can be seen running through the window in the trailer of the 8th episode. And third, the most important episode of the show leaks.

If RJ was McAllister, then everybody would be extra cautious about this week's episode. Obviously Heller was trying to deceive us, but he over-did it. Plus, nobody takes the main event out of the series before it ends. So I believe McAllister is not RJ.

But all these do not change the fact that this show is not working any more with a different story every episode. We've seen enough of a routine murder and Jane finding the killer. And the stupidest idea of all time is Lisbon not being in charge. I mean, she's like a whole new character now and i don't like it. I miss our Teresa Lisbon, the boss version.
