A small girl from the Enterprise-D, the youngest of the seven children abducted by the Aldeans in When the Bough Breaks, whom Rashella takes as her own daughter.
Alexandra is a young child living aboard the Enterprise-D with her family in 2364. She appears in the first-season episode When the Bough Breaks.
She is the littlest of the children whom the Aldeans beam away from the ship to be the next generation of their childless world. The Aldean Rashella, who longs for a child, chooses her at once and is the most reluctant of her people to consider giving any of them back.
Wesley Crusher, the eldest captive, looks after Alexandra and organises the others into passive resistance and a refusal to eat. When the Aldeans finally accept that they must change, Rashella hands Alexandra back, and the girl is last seen on the bridge with a rather awkward Picard.
