Aidan Foster is a fictional character from the Australian soap opera Neighbours, played by Bob Morley. Both the character and Morley's casting was announced on 19 June 2011. The actor began filming his first scenes that same week. Aidan was introduced to Neighbours as a love interest for established character Chris Pappas (James Mason). Morley revealed that Aidan's sexuality did not affect his decision in accepting the role, as it does not define him. Morley was initially contracted for six months and he stated that he was happy to stay with the soap for longer. He made his first screen appearance as Aidan during the episode broadcast on 19 August 2011. Morley took a ten-week break from Neighbours in April 2012 to appear in the feature film, Blinder. He made his final appearance as Aidan on 17 January 2013. Aidan is a nurse who works at the local hospital in Erinsborough. He is openly gay and comfortable with his sexuality. Aidan had many relationships in the past, making him more experienced than Chris. He is confident, trustworthy and likes to seize the day. Aidan meets Chris after he is brought into the hospital and he becomes endeared by him. Even though Aidan questions his decision to get involved with a younger, less experienced guy, he and Chris eventually begin a relationship. The characters became Neighbours' first ever gay couple and they later shared the soap's first male gay kiss. Morley praised the producers for not sensationalising the kiss, which gained positive feedback from viewers. Morley's break from Neighbours in mid-2012 led the writers to improvise a breakup for Aidan and Chris, which played out in May.
