Supergirl must get rid of Reign, but what happens when Reign tells Kara that they are sisters and that their mother is still alive? Will Kara believe her or will she forget that family bonds us all? (Reign's real name in this is created by me and Kara and Reign's aunt 'Amara' is also created by me) I do not own the characters of the CW show "Supergirl" I just want to explore some scenarios with them in the story.
