Quote #4
ASH: Now, we're assuming it's feeding him oxygen. If we remove it, it could kill him.
DALLAS: I'm willing to take that chance. Let's cut it off now.
ASH: You'll take responsibility.
DALLAS: Yes, I'll take responsibility. Get him out of there.
For the alien species, mortality isn't just something to take from the characters. It is a tool to use against them. It keeps Kane alive as if it knows that Kane's survival is necessary until it can accomplish its deadly task.
Quote #5
DALLAS: Anybody want to say anything?
And … silence. In Alien, there is no need to pray to a God for Kane's soul. Death is final.
Quote #6
LAMBERT: Could he want Brett alive?
RIPLEY: What?
LAMBERT: Could Brett be alive?
RIPLEY: No. I mean, I don't think so.
Fair question. As we learned previously, this species uses mortality as a tool allowing it to manipulate its prey. Only God—and some deleted scenes found only on your DVD—know what ultimately became of Brett.
