So, what's up with that guy?
When the geologist and biologist get trapped in the thing, and he is talking to them over the coms, he seems to wink and laugh a little at one of his crew, as if he is happy they are trapped, or something.
Then, later on, when he is talking to them at night, when they find all the dead engineers, he says that their signal was weird, but we clearly see he is looking at a super-HD camera feed from them, and he seems to go out of his way to fuck with them about the potential life-form.
Just wondering if anyone has any theories. He seems like a good guy, who is no more in the loop than anyone else, but these little hints may suggest otherwise.
