Izzy Hoyland (played by Natalie Bassingthwaighte), the woman responsible for one of Karl (Alan Fletcher) and Susan Kennedy’s (Jackie Woodburne) biggest break-ups, came back to Neighbours with a bang, and trouble wasn’t far behind her.
Revealing that she was now a millionaire after the death of her 89-year-old husband, Izzy quickly caused a rift between Karl and Susan with a generous donation to the new hospital wing.
A suspicious Susan could only watch on as Izzy used the donation to get closer to Karl, massaging his ego by naming the hospital wing after him.
As the Kennedys clashed, Izzy quietly mulled over her plan, pondering her next move in her secret agenda.
Elsewhere, Tyler Brennan’s (Travis Burns) world came crashing down around him when he was sentenced to 20 years behind bars for the murder of his father Hamish Roche (Sean Taylor).
The news sent shockwaves through Erinsborough and devastated Tyler’s girlfriend Piper Willis (Mavournee Hazel), who tried to save him from jail with a disastrous plan to go on the run.
There was further heartbreak for Piper when she went to visit Tyler in prison and was found herself on the receiving end of a viscous outburst.
Telling Piper that he blames her for having to plead guilty to murder, Tyler dealt Piper a devastating blow when he told her that he doesn’t love her and never wants to see her again.
As one couple fell apart, Paige Smith (Olympia Valance) and Jack Callahan (Andrew Morley) found themselves unable to deny their attraction and fell into bed together.

Struggling to conceal her guilt, Paige decided a trip away camping would help, but a shock awaited her when they turned up at the campsite.
Staying in the tent next to them was Jack and his unsuspecting girlfriend Steph Scully (Carla Bonner), putting the deceiving pair in a tight spot, having to keep their sordid romp a secret.
Also this week, the truth about who was spying on Toadie (Ryan Moloney) and Sonya Rebecchi (Eve Morey) at their vow renewal last year was revealed when Sindi Watts (Marisa Warrington) made a shocking comeback.
Revealing that Fake Dee, Andrea Somers (Madeleine West), is back in the country and more obsessed with Toadie than ever, Sindi left Toadie with a dilemma when she handed him Andrea’s telephone number.
Struggling to decide what to do with the new information, Toadie turned to Andrea’s daughter, Willow (Mieke Billing-Smith) for advice, who told him to destroy the number and forget all about the scheming doppelgänger.
However, unbeknownst to Toadie, Willow had a good reason to discourage him from contacting her mum, telling Sindi that a devastating truth awaits the Rebecchis.
