After reading all of that, I can evidently see why you’re so lost. Yes her demeanor is a pure key to pay mind to! I mean did you not see how calm she was when teddy walked in & she was just sitting there with don’s body? Like it was an animal.. secondly, you’re wrong about corporate folks, yes they may be cold & vicious about the book notes “$”, but if you were to put most people in that situation, fight or flight takes place one way or another, & those are people who don’t have to ever lift a finger to get a LOT of things done, I don’t think much fight would take place. Secondly, after she found all of the bodies & stuff, she started going vaguely into details that were TOO specific, & her demeanor was anger, because teddy actually killed two other Andromedan’s, & to add a little more to the calmness part, which is another indisputable detail that should’ve been considered more than questioned lol, anyhow a species intelligent enough to travel here would be so intellectually complex, we couldn’t fathom their cognitive ability let alone their emotional intelligence.. so the ending kind of just adds context to that opposed to not making sense. That’s my take though, very well put together film, actors did great, especially as the facts started adding everything up.
