Hannah Wilson
Oscar was introduced to the show along with his twin sister Evelyn (Philippa Northeast) and their aunt Hannah Wilson (Cassie Howarth), creating a family for established character Zac MacGuire (Charlie Clausen). Oscar is portrayed as being a quiet, funny, headstrong teenager. He and his sister entered the show as part of an unusual storyline focusing on a cult. The twins were forced to join the cult by their father Ethan (Matt Minto), which made Oscar uncomfortable and left him struggling to "maintain his individuality". Oscar and Evelyn's early storylines focused on their escape from the cult and Ethan's attempts to get them back.
