Just watched the leaked episode and compared it with the s06e08 promo ( 30 seconds).
3 scenes are out of place. At 0:08 they used a scene from an older episode( the one with the gun in the box) at 0:18 when  mcallister enters the church, there should be Bertram's body lying at the feet of Jane as seen in the episode and finally at 0:19 a lot of peolpe are saying that they can see a ring on the left hand of the guy. Even if there isn't any ring , this scene is not on the leaked episode. So my point is if indeed RJ is mcallister it would be a shame for the way all goes down at the church, we expected something more. If its not and they just kept the core of the episode while changing the last scenes .. good for them and us of course. will find out soon enough
