Amanda Lemmon is one of the two protagonists of It Takes Two (the other being Alyssa Callaway). She is an orphaned girl who can play stickball just as well as any boy. She wishes to be adopted, but not by the Butkises. Instead, she and her social worker Diane Barrows, share the same goal: for Diane to adopt her. She and her look-alike, Alyssa, wish to get the latter's father to marry Diane in order for this. She is portrayed by Mary-Kate Olsen.
