If they don't know for sure, they all must be imagining who the one to kick the bucket is. I mean, they have many more clues and evidence than the average viewer and such a big thing can't be kept a secret until the very moment they receive their scripts. I don't buy it, sorry. I'm more inclined to think there's no better argument for silence than "shut up or you go next."
