Big twist left out
A quick question that I have.
Decided to watch the first Alien, the directors Cut. After seeing many years the original version, during this pandemic I've wanted to see the other version also and saw something that blew me away.
In the original Alien, Dallas disappears without any trace and his wareabouts are left without an answer. But in the directors cut, we see that Ripley discovers the alien nest where Dallas has been impregnated with a xenomorph, near the body of Brett, who is becoming an alien egg (?).
Why did a big twist like this was left out?
