Dallas: Something has attached itself to him. We have to get him to the infirmary right away.
Ripley: What kind of thing? I need a clear definition.
Dallas: An organism. Open the hatch.
Ripley: Wait a minute. If we let it in, the ship could be infected. You know the quarantine procedure. Twenty-four hours for decontamination.
Dallas: He could die in twenty-four hours. Open the hatch.
Ripley: Listen to me, if we break quarantine, we could all die.
Lambert: Look, could you open the god-damned hatch? We have to get him inside.
Ripley: No. I can't do that and if you were in my position, you'd do the same.
Dallas: Ripley, this is an order. Open that hatch right now, do you hear me?
Dallas: Ripley. This is an order. Do you hear me?
Ripley: Yes. I read you. The answer is negative.
