Problems with the leaked episode?

All over this wiki I have seen people complaining about how terrible the reveal was... I already know who he is (he was my number one suspect for awhile after Fire and Brimstone, I thought he just fit the character the best, especially after Wedding in Red), but I have not seen the episode... I already know he dies and I even pictured how that would go (for those who saw the episode, tell me if this is correct- they meet in a church, Jane shoots him, RJ somehow manages to escape from the church and they chase each other until they come to an outdoor secluded area like a park, where Jane strangles him to death... I came to that conclusion from the promo and the TV Guide article). Any ways, I was hoping that those who have seen the episode and were disappointed would please tell me why with the comment section.
