What was the xeno doing in Alien at the end???

@bigmike "had some of Kane's DNA and, thus, his knowledge" Really?

If you believe the xenos have a 4 day lifespan, then Aliens does not make sense. The marines arrive after contact had been lost with the colony for a fairly long time, and the marines even have to go into hypersleep to travel to the colony. only two colonists remain alive, yet there are hundreds of zenos ready for action. the xeno in Alien was there because it was intelligent enough to know the ship was on self destruct and that was an escape vehicle, and was taking a nap cuz of a very full day of work previously.

@beyondthebloodplain I'm pretty sure I read something that stated that because the alien was incubated in Kane that it took on some of his memories or knowledge. The alien takes on some traits of the host, such as being bipedal or a quadraped like in Alien 3. Or...it could have gone there to die peacefully like Ridley has said.

@bbbici Yeah, I guess it did need a good nap after a hard days work. LOL James Cameron pretty much blew the 4 day life cycle theory out the window because it was much longet than four days for the marines to get there. That is true.

I agree with bbbici - the four day life cycle doesn't compute considering the travel time of the Sulaco to LV-426.

I don't doubt the 4 day life cycle given it comes from RS mouth...however the math doesn't add up...in Aliens Ripley claims that the Alien killed her crew in 24 hours...but yet the original creature was nestled up to die on the Suloco after only a day to day and a half?? just sayin'...

@Xeneophobe: In the words of Dan O'B: "The Alien is Omnisexual" LOL
