Elsewhere, the reappearance of David Ames's character is bound to raise eyebrows at the hospital, as viewers last saw Dominic leave Holby in shame after jeopardising the career of colleague and mentor Antoine Malick.
The pair had a one-night stand but Malick later rejected Dominic, causing him to lie under oath in order to get revenge. As he makes his return, Dominic will have to work hard to regain his standing with his colleagues as they wonder whether he can be trusted.

Holby City's executive producer Oliver Kent commented: "We have some great storylines coming up and the arrival of Raf, Adele and Dominic will definitely shake things up at Holby City. These characters will be played by very talented actors and I know Holby fans - old and new - will warm to them instantly."
