* In the first game, an exchange of E-mails soon after clearing the medical level:
-->'''Lansing''': Be careful, we believe SHODAN is trying to jam----''*static*''
-->'''SHODAN''': I prefer a ''quiet'' station, thank you.

* Hacking a replicator will reduce its prices and allow access to better items. The lone exception to this rule is in the movie theater lobby, where hacking the vending machine instead results in snack food that costs over 800 nanites.

* In the mall on the recreation deck, Xerxes calmly announces that there there are 162 shopping days left until Christmas and that working overtime twice a week will give a crewmember enough money, even though there is nobody left on board who is in any position to care about Christmas. Bear in mind that most of his announcements are about the ship's security system and the glory of The Many.
