i haven't got a f@cking clue!!!
somehow it's got the facehuggers
ability to inpregnate hosts, but
i don't know how predator dna would
make that happen...
I dont think anyone was expecting it, because obviously there was no Queen because the Predalien took its place, so the directors had to think of a way for the Aliens to reproduce therefor making the movie better.
The predalien was a young Queen, you could actually see the crest on the back of its head. I don't remember it ever actually producing eggs as this topic claims though...
