1. Mackenzie gets tough with Ryder and Chloe
Mackenzie is outraged when Ryder and Chloe park their new food truck outside Salt, setting themselves up as direct competition. When Mac points out that the young couple are lacking a key permit to be there, Ryder and Chloe are temporarily defeated and have to move to the caravan park instead.

2. Ryder and Chloe's rivalry with Mac hots up
Ryder and Chloe wind Mac up further by handing out flyers for their food truck on her turf at the Surf Club. Mac retaliates by drawing up her own flyers, which feature enticing offers for Salt's customers.
When Ryder and Chloe secure their missing permit, they park the truck back outside Salt. Mac ups the ante by grabbing a megaphone and stealing their customers away with another set of highly generous offers.
Ryder and Chloe feel defeated, until Chloe takes things a step too far by shouting about how she has supposedly spotted a rat at Salt.
3. Alf forces Ryder to be honest
Mac insists that there was no rat, but Chloe sticks to her false story. Alf encourages Mac to take the claim seriously, regardless of how dubious it seems.
Later, Alf informs Ryder that Mac had to close up for half a day and spend money to prove there was no rat. Ryder's guilt is piqued, so he shocks Chloe by coming clean with Mac about their dirty tactics.
4. Justin begs Christian for help
Justin continues to struggle with his painkiller addiction and he rows with Leah when she questions his mood swings. Christian witnesses the bust-up and tries to encourage Justin to be honest with him.
Justin reminds Christian that he's in chronic pain and his short temper is understandable in the circumstances. He begs Christian to give him a prescription and claims that his current doctor has given him the wrong medication.
Christian suggests a different approach, pointing out that Justin may need to come into the hospital for more tests.
5. Christian's latest adventure takes a shocking turn
Christian heads out to pick up his wedding suit, ahead of the planned trip to Melbourne for the ceremony. However, when he spots a sign advertising skydives nearby, he impulsively changes his plans by heading inside for another spontaneous adventure.
Christian signs up for a skydive, but before he gets a chance to head to the skies, fellow jumper Rachel crash-lands. Christian helps to treat Rachel at the scene and continues to oversee her care when she's transferred to Northern Districts hospital.
6. Tori is left devastated
Tori realises something is amiss when she receives a call to tell her that Christian hasn't picked up his suit. With Christian so distracted by Rachel's case, it's left to Jasmine to call Tori and reveal where her husband-to-be is.
Tori heads to the hospital and tries to arrange for another neurosurgeon to look after Rachel. Christian declines this and insists that it needs to be him, claiming that it was destiny for him to be at the airfield and save Rachel.
Christian makes it clear that he's choosing Rachel over the wedding. Tori is distraught as Christian insists they'll need to postpone.
7. Justin reacts badly to the news
Justin is stunned when he learns that Christian has pulled out of the wedding. Unable to control his temper, Justin smashes crockery from the dining table and rants at Christian.
Later, Leah is horrified to find Justin's secret stash of painkillers.
8. Justin denies his problem
Justin makes excuses for his secret stash of medication, but Leah doesn't believe him. She opens up to Irene about the situation.
Later, Leah compares Justin's issues to Brody's drug addiction. Justin loses his cool in response, ditching his medication down the sink to prove that he doesn't have a problem. However, once Leah's back is turned, Justin tries to retrieve the lost pills.
9. Ziggy bears the brunt of Justin's anger
Ziggy questions Leah about Justin's troubles. Leah chooses not to reveal what's going on, but Ziggy can still sense that something is wrong.
Ziggy tries to speak to Justin the next day, but he responds angrily by firing her. Ziggy realises that she'll have to find a new job, but feels deflated by the challenges of the search.
10. John receives a shock
John confides in Stephen, another previous victim of Susie's, and decides to hire a private investigator to track her down. However, he's stopped in his tracks when he receives a text message which is seemingly from Susie.
John optimistically takes this as a sign that Susie feels guilty and wants to make amends. Stephen suggests otherwise, insisting that manipulative Susie can never be trusted. John considers going to the police with the information, but Stephen convinces him to sit on the discovery for now.
11. Tane gets a new job
Roo worries about Alf when he has a funny turn. It's clear that Alf is overworked following Nikau's decision to step down from the bait shop job. Tane agrees to fill in for Alf until he finds a more permanent employee.
However, Tane is presented with another opportunity when Mia discovers that he had previously approached Jasmine about wanting to work at the gym. Mia decides to give him a job, which means a fresh start for Tane.
12. Nikau receives worrying advice
Allegra gives Nikau some advice about the challenges of modelling, including concerns over body image. She reveals that she takes an appetite suppressant to help her manage her weight.
Allegra gives Nikau a sample, explaining that it's provided to her by a friend. Nikau insists that he has no intention of taking it, but in reality, he doesn't seem to be in a hurry to throw it away.
