Character of Regina in the drama "Ghosts"

Mrs. Alving's maid, Regina, is Jakob Engstrand’s (adopted) daughter. She takes great pride in working for the Alvings. She has feelings for Osvald, though it may simply be that she is attracted to the family's wealth. As soon as she learns the truth about who she is—Captain Alving's biological daughter and thus Osvald's half-sister—she leaves the Alving household in disgust and annoyance.
