My Theory

So after seeing the movie and trying to figure out exactly how the Derlict ship ends up on LV-426 I've come up with this theory. Now this would upset alot of the fans if the next film goes this direction because it would ignore some critical info in Alien. My theory is that Shaw is still pregnant with an alien organisim. After she suits up to go into the ship with Weyland there are a few times where she breaks down in pain. Now at 1st I just dismissed it as her still being in pain from her c-section. But the more I thought about it, it seemed like she was having chest pains. Then she leaves the planet in the SJ ship. We saw that the suit would automatically enclose the pilot prior to take off. So I think that the SJ we see in Alien is Shaw. Of course this theory would ignore the carbon dating in Alien completley.
