Andrea is presumably a high ranking employee within the Weyland-Yutani Corporation and reports to someone called Lorne Lannister. After discovering the existence of Xenomorphs on LV-178, she hires mercenaries to kidnap Alan Decker so that she could exploit his empathic ability to capture a Xenomorph. To this end she makes threats toward his children to force his cooperation. The mission succeeds but in an unexpected way, as while the team manages to capture one live adult Xenomorph they also unintentionally procure two Facehuggers which are already attached to hosts Adams and Elway. While she tells Manning that she intends to help them, Decker believes that they won't be saved, likely just used to breed the Xenomorphs.
Andrea is a ruthless and cold-hearted woman who employs threats and under-handed tactics in getting what she wants; her behavior in this regard even disturbed Manning, who was himself somewhat amoral.
- Following the release of Alien: Sea of Sorrows, author James A. Moore stated that one of the characters in the novel was an undisclosed android. Hints that Rollins may be the individual Moore was referring to include the fact that Decker is unable to read anything from her with his empathic abilities, coupled with her generally cold, emotionless demenor. Moore later confirmed that Rollins is indeed a synthetic, in response to a fan correctly guessing that she was the character in question.
