Ashley is Lisa's twin sister, daughter of Maggie. They both resided aboard a hovercraft full of potentials.
The sisters wanted to surprise their mum for her birthday, hacking into the Matrix to trace her and possibly see her. Ashley jacked Lisa into the Matrix during meal time but the tracing was detected and, as a result, Sentinels located and found the Calappidae.
While Maggie hugs her daughter, the ship is destroyed, killing everyone.
