So... here's a theory based on the clip and Jesus reference for Franco and that he's in the centre of the promo photo. James Franco knows one of them will betray the crew. But how would he know this? Is he any relation to any of the Prometheus expedition? Is he signed up at such a young age to find out what happened? Is he feeling unwell because he KNOWS what's waiting for them? Is he there, undercover (literally in that scene!) to find out what happened to the Prometheus crew and to sacrifice himself for humanity? HMMMMMMM!
