Core Episode Introduction
On Wednesday 15 July 2024, BBC One’s soap *EastEnders* introduced Cleo, the estranged mother of juvenile offender Joel Marshall (played by Max Murray). The character appears in a two-episode storyline that follows Joel’s release from a young-offender institute and his recent assault on his step-mother Vicki Fowler (Alice Haig). In the episodes, Cleo arrives in Walford with Joel and announces she can no longer look after him, forcing her ex-husband Ross Marshall (Alex Walkinshaw) to choose between his new wife and his son.
Background & Context
Joel’s storyline began last August when he told classmate Tommy Moon that his mother had abandoned him, even branding her a “slapper.” Ross and Joel’s arrival in Walford was accompanied by frequent references to Cleo, who had previously contacted Ross to announce a new marriage and then disappeared, leaving Ross to raise Joel alone. In October, Joel knocked Vicki unconscious, prompting a courtroom scene in which Vicki testified against him. The new episodes bring the long-teased reunion with Cleo to the screen.
Casting Connections
The role of Cleo is filled by theatre veteran Mazz Murray, best known for six years as Donna Sheridan in the West End production of *Mamma Mia!* and for roles such as Killer Queen in *We Will Rock You*. Murray’s appearance is notable because she is the real-life aunt of Max Murray, who portrays Joel. Murray said:
> “It was so wonderful to be part of these *EastEnders* episodes as we delve into Joel’s familial past, and my experience was made all the better working alongside my talented, gorgeous nephew Max. And also, my childhood school friend Alex Walkinshaw playing my ex-husband!” — Mazz Murray, Actress
Murray has previously appeared in *EastEnders* twice: as waitress Miranda in 2004 and as Julie, a divorced woman who hired a male escort, in 2017. Her sister Gina Murray (Max’s mother) also featured in the soap in 2014 as hair-specialist Helen.
Plot Implications
Cleo’s declaration that she cannot care for Joel overturns an earlier agreement that she would assume custody after his release. Ross, newly returned from his honeymoon with Vicki, must now decide whether to keep his marriage intact or reunite with his son. The storyline heightens the existing tension created by Joel’s violent act against Vicki and sets up a potential family-rivalry arc for future episodes.
