Next week on Home and Away, Kirby and Theo finally go public with their relationship.

Here's a full collection of 11 big moments coming up.

1. Kirby is shocked as Theo ends their relationship

Theo has doubts about his secret relationship with Kirby after she encourages him to kiss another woman to throw Remi off the scent. He suggests that they should just come clean with Remi and Eden, but Kirby once again refuses.

Theo decides that it's time to stop playing games, so he surprises Kirby by telling her that it's time to end their relationship.

2. Kirby makes a big decision

Following Theo and Kirby's secret split, Remi and Eden question the strange atmosphere at Lyrik's latest band meeting. Theo tries to protect Kirby by making an excuse and taking the blame.

Kirby is touched that Theo would cover for her despite their recent tensions, so she finally sheds her reservations and pulls him in for a kiss in front of Remi and Eden.

Although Remi and Eden are surprised, they decide to keep the peace within Lyrik by being supportive towards Kirby and Theo.

3. Ziggy discovers that she's pregnant

Ziggy returns to Summer Bay following a short trip and announces that she won her latest surfing competition. She heads off to celebrate with a casual surf, but becomes woozy and stumbles back onto the beach.

Summer Bay's new doctor Bree gives Ziggy a check-up on the sand and suggests that she might be pregnant.

Ziggy dismisses this, but takes a test upon her return home and is shocked when the result is positive.

4. Ziggy confides in Dean

Ziggy keeps the test result to herself, but Dean notices her obvious change in mood. Dean is confused when Ziggy suggests that she might give up on her dream of becoming a professional surfer.

Deciding to take the honest approach, Ziggy tells Dean that she's pregnant and fears that she'll have to give up on her pro surfer dream if she becomes a mother. Dean is supportive in response, promising her that they're in it together.

5. Marilyn receives an unsettling photo

Marilyn and Roo continue to disagree over whether Summer Bay newcomer Heather can be trusted. Roo defends her new student by explaining that Heather once had to give up a baby after having an affair with a married man.

This revelation worries Marilyn, who seems to know something about Heather's supposed backstory.

Later, Marilyn finds a baby photo on her doorstep alongside a taunting note, which reads: "Guess who?"

6. Heather's secret is revealed

Marilyn storms over to Heather's caravan to confront her, accusing her of leaving the photograph on her doorstep. Heather feigns innocence and their row is broken up by Nikau and Roo.

Later, the truth about Heather's secret agenda is revealed to viewers as she pulls out her birth certificate during a moment alone. Her birth mother is listed as Marilyn Chambers.

7. Nikau gets caught up in the Heather drama

Marilyn tries to make amends with Nikau after he witnessed the row at the caravan park. She also takes the opportunity to push Nikau for information on Heather, but he points out that he barely knows her.

Marilyn loses patience with Nikau, harshly asking why he's moving on from Bella so quickly and sleeping with a woman he barely knows.

8. Marilyn's loved ones stage an intervention

Marilyn's latest outburst concerns her closest friends, who can tell that something isn't right.

Leah and Roo decide to spring an intervention on Marilyn, but their attempts lead to another row. Roo ultimately storms off when she decides that she's had enough of Marilyn's behaviour.

9. Nikau and Tane worry about Cash's presence

Cash continues to stay at the Parata house, but Nikau and Tane worry that the bikies could rumble them for cooperating with the police if he sticks around for much longer.

Tane broaches this subject with Felicity, explaining that their safety could be threatened if Cash doesn't move out. Felicity offers to speak to Cash, unaware that her brother has heard every word and is clearly hurt.

10. Cash vows to move

Cash tries to take matters into his own hands by arranging a move to the caravan park. Felicity finds him packing and immediately intervenes.

Felicity refuses to let Cash move out, insisting that he's staying put at the Parata house where she can keep an eye on him.

Although Tane is supportive, he starts to despair over the situation and asks Rose for any updates on the bikies' court date.

11. Rose discovers a threat to Cash's life

Rose searches through the ongoing police investigation into the biker gang. She's disturbed to find that there's still a threat to Cash's life, as the bikies have ordered a hit on him. Rose decides to tell Cash, who barely responds to the revelation.

The next day, Cash turns up at the police station and asks to see the details for himself. He's visibly struck to see that the hit on his life has been priced at just $10,000. Cash bitterly questions whether this is all his life is worth.

Home and Away airs weekdays at 1.45pm on Channel 5 and 6pm on 5STAR. First-look screenings air at 6.30pm on 5STAR and the show also streams on My5.
