Some people on the forum believe that this movie is going to be an interquel. I mean something could happen within a span of twelve days, if we happen to go by SM's timeline website. But there are some problems which I have with the interquel idea.. I mean sure it is a good way to explain how the egg got onto the Sulaco but how is Ripley and Hick's age to be explained? More so.. Wouldn't Hicks more or less be out of commission considering the injury which he had sustained?
I mean.. I don't know how long it takes to heal from an acid burn wound, especially one as severe as Hick's.. but I wouldn't expect him to be walking about in twelve days. And then one would ave to explain how Ripley suddenly gained back twenty something years of youth if this leads to the events of Alien 3.
