Jenny Hardy grew up with two brothers. She later on became the owner of a restaurant in Brookyln and was very close to her brother, Ryan Hardy. She was present when her brother introduced Claire Matthews to her, to which she later told her brother she likes her. She encouraged her brother to pursue her, knowing he loves her, but Ryan believed he was her past.
Since then, Jenny had to help her brother through his drinking problem, to which she finally had enough and left him to take care of himself.
She was kidnapped by Maggie Kester in an attempt to bring down Ryan Hardy. She was forced to watch as her brother was being hurt by Maggie as she placed magnets on his chest to stop his pacemaker, to which Maggie revealed she was never going to let Jenny go and kill her after forcing her to watch her brother die. Just as Jenny believes her brother to die, Mike Weston shows up and kills Maggie and saves Ryan and Jenny.
She was later taken into protecting by the FBI, believing Joe's followers may go after her again. She then parted with her brother, thanking him for saving her and the siblings reconnected again to which Ryan apologized for his behavior long ago, leaving on good terms again.
Jenny now lives in Boca and even though they live on opposite coasts of the United States, she seems to have a good relationship with her niece, Max.
