Liza got the shock of her life in 2001, when Mia Saunders revealed herself to be her half-sister. Eventually, Liza and Mia formed a sisterly bond and Liza even financed the money to upstart Fusion, the new cosmetics company that Mia co-founded in late 2002 with Greenlee Smythe, Kendall Hart, and Simone Torres. In late 2004, Liza, with Tad's help, went on the run with Colby in tow. Her last appearance was in early 2005. However, Colby eventually returned (rapidly aged to her teenaged years) to Pine Valley to live with Adam. Initially, she has exhibited all of Liza's worst character traits from the '80s, including consistent spoiled behavior, and a false statutory rape allegation against Erica Kane's son Josh Madden. However, Colby has put most of such behavior behind her, and has recently emerged as a more sympathetic character.
