Floriana Lima (The Family) will be playing the role that originated in the post-Crisis Superman comics. In the show, Maggie Sawyer will be a detective for the National City Police Department who takes a special interest in the cases involving aliens. In the comics, the openly lesbian character was at one time engaged to Batwoman.
On Smallville, Maggie Sawyer was played by Jill Teed.
The new role will be a series regular, so welcome to the family, Ms. Lima!
