Catherine Hamilton-Kane to Mary Hamilton[src]

Mary is very excitable, talkative, friendly, and kind of a social butterfly; she is described as her step-sister Kate Kane's polar opposite[9] and one of Kate trainers dubbed her as "Girl Who Talks Too Much".[1] Despite coming off as a ditzy socialite, Mary is a very kind-hearted individual who will go to any length to help those she loves and the people in need, such as Gotham's underserved communities.[3] Due to the bond she shares with her step-sister Kate, Mary is one of the few individuals who can talk her around.[4]

Because of their differences however, Mary and Kate were never really close, much to Mary's dismay, though she still tried to be friendly and supportive of her step-sister. As a result though, Mary harbored some resentment towards Kate for dismissing and only seeing her as a replacement for the latter's biological sister, Beth. Mary even lashed out at Luke Fox over how Kate still favored a serial killer to her despite all her best efforts to be a good sister[6] and began questioning Kate's love for their their family after she refused to talk to Mary since she had "work to do" when their parents were about to divorce.[2]

Mary is also quite empathetic and sensitive; she was horrified after discovering that her mother had manipulated the DNA test on Beth's alleged skull fragments in order to gave Jacob and Kate closure,[6] having a very hard time forgiving Catherine for this deception. Mary felt great sorrow when her mother and adoptive father were about to divorce,[2] and was devastated for being unable to reach and act more sisterly with Kate.
