Izzy moves to London and begins an affair with Pete Gartside (Daniel Schutzmann), a married professional football player. Pete breaks up with Izzy, but they later decide to start again and raise her baby together. Karl and Susan meet Izzy while they are in London to see their son Malcolm (Benjamin McNair). Izzy turns up at their wedding and goes into labour. Karl is then forced to deliver her daughter, Holly (Chaya Broadmore). Susan later overhears Izzy saying that Karl is Holly's father and she tells him when they arrive home. Karl later tells Susan that Izzy would like her to be Holly's godmother and she agrees. In 2013, Izzy sends Holly (Lucinda Armstrong Hall) to stay with Karl and Susan, while she goes on a cruise with her new partner.
