Ruby is Poppy's older cousin and she lives in London. The girls arrive in Erinsborough together and go to Charlie's bar. They get to know Zeke Kinski (Matthew Werkmeister) and Ringo Brown (Sam Clark), before talking to Lucas Fitzgerald (Scott Major) and Michael Williams. Ruby likes that Michael is a school principal and that he has a strong relationship with his daughter. Poppy tells Ruby to give Michael her number and she does. Ruby and Poppy return to the bar and see Michael and Lucas again, they tell the guys that they have changed their plans about passing through. Poppy asks Michael why he did not call Ruby and he replies that he did not think she was serious. Ruby says she was and asks Michael to breakfast the next day. Michael and Ruby get on well, but when they go to the bathroom, Michael's daughter, Natasha, tells Poppy that her father has a different girl each week. Poppy tells Ruby, but Michael realises that Natasha was trying to put Ruby off. He and Ruby then arrange another date. Michael and Ruby text each other and when he gets home from work, Ruby and Poppy are waiting for him. Michael and Ruby then go out to dinner. When Natasha asks Ruby and Poppy to go shopping with her and Summer Hoyland, Ruby declines. Ruby and Poppy spot Natasha outside and she asks if they can hang out. Natasha then says that all men are gross and Ruby tells her that her father is not. Ruby believes that Natasha does not like the idea of her going out with her father. She tells her that she and Michael are having fun and that Natasha is making too much of a deal out of the situation. Natasha tells her that she does not want Michael to get hurt. Ruby meets up with Michael and tells him that she is going home because she misses London. She says that she really likes him, but it is better to leave now rather than later. Natasha runs into Ruby and Poppy at Harold's Store and tells Ruby to meet up with Michael before she goes. Ruby tells her that she and Poppy have too much to do, but Poppy thinks it is a great idea. Ruby says that she will have to say goodbye to Michael all over again and that it was hard enough the first time. Ruby and Michael are set up by Natasha and they talk. They tell Natasha and Poppy that they have decided to end everything, until Poppy tells them to have an entire relationship in one day.
