Originally a quote from Alien, coming up towards the end of the movie. Lt. Ripley has just inherited command of the beleaguered ship "Nostromo", and hence gained direct access to the ship's computer, known as Mother.

Although I think the quote itself is nothing special, the scene is great. This is the point where Ripley finds out that the Company had at least a vague idea of the threat on planet LV-426, and that the entire crew of the Nostromo was classed as expendable. As she reads this, she is attacked by Ash, the android science officer in charge of this little piece of treachery, and it's at this point that Ripley begins to turn into the kick-ass action hero seen in the later Alien movies.
