In follow-up scenes next week, Darcy tries to make some useful new contacts as he takes a tour of Eirini Rising.
During the visit, Darcy becomes concerned about Vera Punt's health as she complains about severe stomach pains.

Darcy's cautious approach proves to be the right one, as Vera is diagnosed with a swollen appendix.
As Karl kicks himself for misdiagnosing Vera, Darcy slyly twists the knife by questioning whether his medication is affecting his judgement.
With Darcy in town to open his own health clinic, the danger is that he could be sneakily stepping in as a competitor for Karl while the Erinsborough favourite is distracted by his own problems.
The final straw for Karl comes when his wife Susan also questions his judgement, which leaves him feeling badly betrayed.
As Karl snaps back at his wife, will Susan realise that something isn't right with him?
