Folks,
Emotions are clearly running high here.
Haven't seen the 'leaked/hacked' video, but definitely get the gist of what's in it.
Can't say then if it's real or not, but, as far back as 1980, CBS did tape multiple versions of the 'Who shot JR' cliff hanger (which, if I'm correct, may have actually been the show that kicked off the whole notion of season ending cliff hangers) whereby each of the characters in fact had a scene during which they shot JR.
The purpose then (and this was well before the internet made it substantially easier to spread information) was to keep the reveal secret, even from the actors, so as to protect it from becoming known to the public in advance.
Not saying that's what's happening here, but for those who believe it's an impossibility, it has been done before by this very network.
