Neighbours, Terese Willis is surprised when she discovers that her brother Nick Petrides is in town.

As first revealed late last year, actor Damien Fotiou has been cast in the role of Nick, an oncologist who is the brother of established regular Terese.

Karl Kennedy is excited to be interviewing a potential new doctor for the hospital, unaware of the connection he has to Terese. However, Nick doesn't share the same enthusiasm that Karl does and is abrupt with him.

When Brad sees Nick with Karl, he is immediately disturbed and returns home to tell Terese who he saw. Although Terese is initially shocked, she later sees Nick for herself and demands an explanation as to why he didn't tell her he was in the area. Nick has to do some fast explaining to Terese.

After Nick explains his reasons, Terese is soon inviting him for dinner, although Brad's unease over the situation is palpable.
