Trish Walker is a former child star turned radio host and Jessica Jones's adoptive sister, having grown up alongside her after Jessica's family died and Trish's mother took her in. Fiercely protective of Jessica despite a strained history with her, Trish has repeatedly involved herself in Jessica's cases, at times testing the limits of how far she is willing to go to matter the way Jessica does.
