Don't get me wrong... it would probably be cooler if it were cannibalism. That would certainly make the scene more viscerally shocking. Certainly a stronger story point than eating a really big turkey with all the trimmings.
But I didn't get that impression when I saw the scene, so I was wondering if I missed something. Or if people were offering speculation as what was really happening. I guess my question is: do we really know that or are we speculating?
I may load up early access this evening to go over the scene again carefully.
