I've seen the leaked episode a couple of times now, and managed to reconcile that McAllister is RJ. 

However two things don't fit:

1) It says it was filmed in 2012

2) It is also called Episode 7564 (not 5608 as it should have been after the last one was called 5607)

Lastly, for all the people so proudly proclaiming it is the real episode - we were all desperate to see the past few episodes, each one of them was big on their own this season so far. Yet how come nobody on here managed to spring a leak for any of them? Especially the episode that was missed the US due to the football? I don't remember seeing any CBS website links to uncut/unedited versions of that on here. It just seems a little too convenient to have this episode show up five days before the real one. Who even leaked it in the first place? Does anyone know? Was it even leaked on this website first? And if so, why didn't we get any of the other episodes like this?

(All the magazines have been writing previews about all the other episodes too, so I won't accept the excuse that this was the most important episode, so it was put up on the website for previewing to the press)
