Yeah, that had me scratching my head as well. Also, it seems a bit odd that this group can just take off in a ship without anybody caring. W-Y is depicted as this very controlling company. Were they all off-duty that day? Is anybody allowed to take off into space just like that? Seems a bit odd.
And the fact that nobody from W-Y was sent to check on the station was really pushing it. But I could overlook that for the sake of the story moving forward.
It also bothered me a bit how they speeded up the gestation of the alien again. Was this a new record? Can't remember if there was a faster transition from facehugger to chestburster to fully grown adult. And where the hell did they get so many eggs/facehuggers from?
It all seemed like a bit of lazy writing to me...
I think I'll go and watch again this week, I want to pay attention to all the details, see if I missed something.
