Still, that feverish fervor seems to be reaching a peak. And you can hardly blame fans for their curiosity; AMC’s marketing campaign has been a master class in suspense. The secret has been kept under several locks and keys: all 11 actors on the chopping block reportedly shot a death scene just to protect the reveal.
Both of those videos posted on the last page are still available, I would think they'd have been snatchedT by now if they were legit. I definitely think they would've filmed at least a few different deaths and this might just be one of the alternative ones.
The spoilers from The Spoiling Dead interview sound more real to me.
They shot scenes for all of them getting it, so they're probably just throwing people off (and they're the only ones who'd have access to those scenes anyway)
