Liz was a social worker assigned to Courtney Campbell, who had given birth to a daughter Iona in December 2017. Liz visited Courtney and Iona in January 2018, but Courtney was convinced that Liz's visit was due to Granny Campbell's attempts to have her daughter taken away from her. In August 2018, Liz took Iona into temporary foster care after Courtney's arrest for drug dealing, but returned her to Courtney and her partner Jesse Donovan in November after the charges were dropped.
