Flighty, abrupt, and snappy with her elders, Jolyne in her teenage years was easily considered a delinquent and lost cause. Bitter at Jotaro for being absent from her life, she tried multiple times to catch her father's attention by committing multiple minor crimes and went to jail several times for them. Because of her father's absence, Jolyne was said to be dependent on the affection and approval of those around her[8], and she was ready to cover Romeo's accident, resulting in her being sentenced to 15 years in prison for it.
