But it underscores another fact that Alien 3 was Removed from the likelihood of reality.
The film was millions of miles away from what would likely happen in real life, even factoring in all the requisite sci-fi trappings.
-unlikely that an alien egg would be on the sulaco.
-unlikely that the crew of Sulaco wouldn't do a multi-redundancy check for Alien life forms.
-unlikely that the EEV would end up on a prison planet which happens to be nearby.
-unlikely that the EEV would land right by the penal colony as the medic walks by.
-unlikely that the dog / face hugger interaction would have yielded the results in the film. Most likely, it would have ended just like in Alien: Specimen.
