At the end of May 2016, Carmel and Steph attended the school's sports day along with Connie and Grace. When Connie won the parents race against Steph, Carmel informed Grace that her mum would be in a bad mood for losing. As a result of this, Grace and Connie purposely lost the next race so Carmel would be friends with Grace.
In August Grace and Carmel were good friends. However, after a sleepover Carmel slipped on the trampoline and broke her leg. Once admitted to the ED following help from Connie, it transpired that Steph had been psychologically abusing Carmel and Carmel had been self harming by scratching her stomach. Social services were called, and Steph was left furious and ultimately pursued Connie in her car. This led to Connie driving off a cliff when Steph braked on a corner of the road near the ledge.
