Actress Emily Lawrance has been cast in the role of Sienna, the twin sibling Dodger never knew he had.
Dodger (Danny Mac) learns of Sienna's existence when he finally manages to track down his biological father Patrick Blake, played by former Coronation Street star Jeremy Sheffield.

The cheeky ladies' man is left stunned by his latest life-changing discovery, while Sienna has been tipped to cause mayhem when she makes her arrival in the Hollyoaks village.
Lawrance commented: "Joining Hollyoaks is going to be fun and a great experience for me. It goes without saying that working with Jeremy is brilliant."
Dodger has already experienced his fair share of family dramas this year, as he only recently learned that wheeler dealer Dirk (David Kennedy) is not his real dad.
Recent episodes have seen Dodger struggling with his discovery, so time will only tell how he'll cope with the next revelations.
Patrick and Sienna's first scenes will be broadcast in the week commencing Monday, November 19.
Hollyoaks airs weekdays at 6.30pm on Channel 4, with first look screenings at 7pm on E4.
