Susan remains convinced that Izzy must have a hidden agenda for getting involved with Mal.

Susan, Karl and Toadie Rebecchi all keep a close eye on Izzy to find out more, but they struggle to find any evidence that she's up to something.

Later, Izzy reveals to Karl that she wants to make a dream of Mal's come true – moving back to Erinsborough.

Mal is keen to return home following his years living away in London, and Izzy is eager to join him now that they're together.

Izzy asks for Karl's blessing, but also knows that the biggest challenge will be convincing her arch-nemesis Susan.

Susan is furious when she finds out what's going on, especially when it becomes clear that Izzy is using a possible move for Karl's daughter Holly as a bargaining chip.
