Fifield doing the whole 'xeno crouching infront of Lambert' stance when that merc found him before his rampage reminded me of a xeno and it is clear to see he was supposed to be in some sort of transformed state into a xeno in that. Early footage even had him with elongated arms and a slightly different face, so they seemed to have wanted to go down that road but pulled it back, or at least I didn't notice because the shots of him rampaging were so quick.
I would like to know exactly why he went xeno when Charlie seemed to go the way of the Sacrifice Engineer in the end, even if his sperm was infected with alien dna. I guess what I'm trying to actually say is how are the crew turning xeno, along with the worms, when the Engineer just crumbles away. I guess his dna does reconstitute into the primordial soup, so what the hell does that mean? Life evolved from xeno cells?
Gah!
