As we reported yesterday, actor David Witts has been cast as Derek's son, who arrives in Walford hot on the heels of his sister Alice (Jasmyn Banks).
Joey has been sent to Albert Square by his mum to tempt Alice back home.
When Alice reveals that she wants to stay put, Joey vows to show her what kind of man Derek (Jamie Foreman) really is. Will he succeed in his plan to bring Derek down?
EastEnders fans can see Alice's first scenes tonight (May 10) at 7.30pm on BBC One.
