I just got through watching my DVDs and I was wondering. How does the director explain the 2 face huggers that are in this movie? One impregnates Ripley and one Impregnates the dog. I know they show one egg on the main ship in the beginning but how did it get there? At the end of aLiens I do not see anytime that the Queen could have laid the egg and the other unseen egg. So how can this be? This is really bothering me so I appreciate any theories.
