First off i highlight a simple point and now its cause Anderson f**ked the film up, just like the french fag ruined alien resurrection?
The details we have lie in the story...and when does an alien become a queen? you are either born like that or your not, i think everyone is getting too hyped on a small factor of this film (being the supposed embryo planting scene) and getting to obsessed with the predalien, its ALIENS VS PREDATOR not PREDALIEN VS PREDATOR.
Who cares if its a queen or not? they are all gonna be wiped out at the end of the movie more or less anyway with maybe weyland yutani getting a specimen thus making a backstory to alien
