Home and Away spoilers follow from this week's Australian episodes, which some UK readers may prefer to avoid.
Home and Away aired four new episodes in Australia this week, with a firm focus on Colby Thorne's ongoing murder cover-up.
Mackenzie Booth also took centre stage as she moved in with the Parata family, creating plenty of awkwardness for a smitten Tane.
Here's seven big questions we've been left with after the latest episodes.
1. Is Colby becoming a villain?
Colby has been a divisive figure among Home and Away fans for a while now, especially after the harsh way he treated the Parata family following their arrival in Summer Bay.
In recent weeks, the show has revisited Colby's murder secret, with the shock discovery of Ross's body. Viewers have always known that Colby killed the evil villain to protect his family, but there are worrying signs that he's now enjoying the thrill of the situation.
This week's episodes saw Colby temporarily worry that Ross's DNA could be found in the car that was used to transport his body. Fortunately for him, he later discovered that no traces of Ross had been discovered in the vehicle after all.
Colby was quick to celebrate this news, taking it as a major victory – but Bella and Willow were both shocked that he was so jubilant given the grisly circumstances.
A defensive Colby saw little wrong with his attitude, even though he was upsetting Bella. Is he starting to lose touch with the gravity of the situation? Could he even – gasp – be Summer Bay's next villain?
2. Has Colby already slipped up?
So far, Colby has managed to stay ahead of the game while the police investigate Ross's murder. He, Dean, Willow and Bella have all given police interviews without letting any secrets slip. Additionally, the police haven't found any evidence to link Colby or Dean to the crime.
Despite this, Colby has taken some major risks to keep his cover-up afloat. Aware that his computer usage at work could be tracked, Colby checked on an important forensics report by instead calling the relevant department for details and pretending to be Angelo.
Bella rightly pointed out that this could come back to haunt Colby in the future, as Angelo will be suspicious if he ever finds out about the bogus call. It's difficult to get much past Angelo, so has Colby made a mistake here which could cost him in the long run?
3. How strong are Taylor's feelings for Colby?
Angelo's wife Taylor has struck up a surprising bond with Colby recently, enjoying his attention while her husband is distracted by the ongoing murder investigation.
Colby has ruthlessly used this connection to his advantage, believing that he can use Taylor for information and convince her to defend him to Angelo.
This week, Colby took his games a step further by sharing a passionate kiss with Taylor. They were only stopped from going further when Bella returned home and interrupted them.
Taylor was full of remorse for cheating on Angelo, unaware that Colby was only using her. Could she be developing genuine feelings for Colby – and is she heading for heartbreak since he's pursuing her for all the wrong reasons?
4. Will Mac give into temptation?
Home and Away's ongoing love triangle stepped up a gear this week, as Mackenzie moved in with her boyfriend Ari at the Parata house. This wasn't welcome news for Tane, who still has strong feelings for Mackenzie and didn't want her around.
Tane was open with Mac about how he felt, encouraging her to put them on opposite shifts at work so they'd rarely be at Salt or at home at the same times.
It's no secret that Mac has feelings of her own for Tane, even though she insists they've gone away. Is it only a matter of time before she gives into temptation with Ari's bad boy brother? Watch this space...
5. Will Justin tell Ava the truth?
Justin faced another difficult week, as Tori took drastic measures to convince him to undergo surgery to remove the tumour on his spine. Tori arranged for Justin's daughter Ava to pay a visit, believing that her presence would help to change his mind.
Justin was furious over Tori's meddling, but it was already too late to change anything as Ava's mum insisted that the visit should go ahead as planned.
This left Justin with a difficult decision to make, as he's not sure whether he's ready to tell his daughter about his health problems. However, Justin's symptoms are becoming increasingly apparent and Tori advised that lying to Ava wasn't a good idea.
Will Justin have to take the honest approach with her, despite how difficult it might be?
6. Can Amber win back Dean?
Amber has changed Dean's life forever with the revelation that he's the father of her young son Jai. She isn't stopping there though, taking every chance she can get to make it clear to Dean that she wants them to be a proper couple.
Amber has tried to tempt Dean into the idea of a family life with her and Jai, even though he's currently in a relationship with Ziggy.
Dean has set Amber straight by explaining that, while he wants to be a father to Jai, he's fully committed to Ziggy. But with Dean and Ziggy's relationship fragile again, could Amber still get her wish?
7. Will Roo and Owen become a couple?
The arrival of Evan's twin brother Owen has made a major impact on Roo, forcing her to acknowledge that she fell in love with Evan before he died. The presence of a man who looks exactly like him has been difficult for Roo to process, even though Marilyn believes that it's fate.
A current Home and Away trailer on air in Australia is teasing the possibility of romance for Roo and Owen, questioning whether this is a second chance for Roo. Is it only a matter of time before they start dating, or would it just be too weird for Roo?
Home and Away airs weekdays at 1.15pm and 6pm on Channel 5 (UK) and Mondays to Thursdays at 7pm on Channel 7 (Australia).
