If people think this thread/forum can be harsh, you ain't seen nothing - try visit the imdb board. I'm not even contributing anything over there nor planning to because it's so troll infested.
In my admittingly limited experience here, the mods and users here are doing a great job, even though we can get carried away from time to time.
On the subject - I'm faily certain than Mr Blue who activates the chair will also be the one who sits in it. I don't buy the human angle, filling out the suit and flies the ship etc. Shaw and Vickers are seen running on the ground when it crashes - they cannot be onboard the engineer ship. Neither do I believe that Mr Blue is a mutated crewmember or anything like it - imo he's the real deal - an engineer.
Ms Blonde on the other hand, could turn out to be a total psychopath with a flamethrower.
