And while all of the connections that have formed are different in their own way, their is one unanimous message coming from all the parents – if they don't receive their child's blessing it's game over.

So the stakes are higher than ever.

Ahead of the Blessing Ceremony the parents reunite with their children after a long few weeks of no communication.

"It was great to see mum and see her face to face and not through a screen," Petula's son Drhys says of their reunion.

Heath and Haydn's heart-to-heart brings to light some of Haydn's "doubts" about Michelle.

"She just seems a bit reluctant to open up and you've been hurt in the past, I want to make sure she doesn't hurt you again," Haydn tells his dad.

Kayla – who has had her reservations about her dad Shane's partner Kristy for some time now – finally has the chance to get some things off her chest when she sits down with him.

"If Kayla doesn't like Kristy then I really can't have a relationship in the outside world," Shane admits.

"I'm starting to get a bit nervous now."

Not only do all the kids reunite with their own parents, but they finally meet their parent's new partners for the first time too.

When Priscilla finally meets Roe, it's her chance to grill him about his feelings for her mum Carole.

And when he's given the opportunity to finally open up, Roe doesn't live up to Priscilla's expectations.

"I think Roe's lack of emotional expression is disappointing. I do still think he has walls up," Priscilla tells cameras.

With all the first meetings done and dusted, the kids have one last opportunity to mull over their final decision.

Darren and Petula's Blessing Ceremony

Throughout The Retreat, Darren has been quite a character.

Upon reflection Darren thinks he has said and done some things he wishes his potential step-son Drhys hadn't have seen.

But when it comes to the Blessing Ceremony it's not Darren's larrikin antics that has Drhys worried.

"The distance is a worry, we do live so far away," Drhys says.

And Tess agrees that it would be difficult for her dad – who lives in Queensland – to maintain a relationship with Petula – who lives in Western Australia.

But Darren is adamant that despite the distance "the connection won't go away".

Not to mention that Petula already had a coastal move planned before she met Darren.

And on that note both Tess and Drhys give their parents their blessing.

"The connection that you guys have developed over these past weeks has been incredible to watch," Tess says.

Roe and Carole's Blessing Ceremony

There's no denying that Carole is into Roe, but Priscilla isn't sure that the feelings her mum has are being reciprocated.

And even though Roe's son Sachem thinks "Carole would be an amazing person for his dad", he worries that Roe "doesn't know how to open up".

When the four sit down, it's clear that Priscilla and Sachem are on the same page.

"The attraction felt physical and I wanted to see more," Sachem says.

And while Carole sees where they're coming from she says "you can't push someone" into being ready to open up.

"With time, I think your dad will break a few more walls," Carole says to Sachem.

But despite Carole's willingness, Priscilla "only wants the best" for her mum and decides not to give her blessing.

And after noting that his dad "still has a lot of concrete up", Sachem decides now is not the right time to give his blessing either.

While Carole is disappointed she "respects" the kids' decision but says she thinks she still might catch up with Roe in the future.

Heath and Michelle's Blessing Ceremony

There's one glaring question about Heath and Michelle's relationship – is Michelle falling for Heath as much as he's falling for her?

Even Michelle's daughter Chloe has Heath front of mind in the decision making.

"I'm a little bit worried that Heath may get hurt in this situation just because he is diving in pretty quick and pretty heavy," Chloe admits.

Haydn wastes no time in trying to find out if Michelle "is ready to receive the love that his dad is willing to give".

"What are your intentions for my father?" Haydn asks the second they sit down.

"I would like to purse it and see what happens," Michelle reassures Haydn.

And while it's an answer Haydn is happy to hear he is still concerned about the letters he and Chloe received from their parents.

In Heath's letter he called Michelle "the love of his life" while Michelle didn't mention Heath in her letter.

But Michelle explains that she just wants to take "baby steps".

In the end, Chloe says she "has a lot of respect" for Heath and gives them her blessing.

After a little hesitation, Haydn says he is "willing to open up and let Michelle into their lives".

"It's everything I want for my dad and more," he tells cameras.

Shane and Kristy's Blessing Ceremony

Shane and Kristy have been the strongest couple in The Retreat but after a few hiccups, Kristy worries Kayla might think she's "a bit of a diva".

Kristy's daughter Milli says "there's no bloody way she's not giving her blessing" to the couple.

"But I'm not sure where Kayla's head is at," Milli admits.

And Shane knows his daughter "won't hesitate to say no" if she doesn't feel in her heart that things are right.

EPISODE 3 RECAP: Cracks are showing for the strongest couple

After previously hearing Kristy admit she'd like to party with the girls as much as she would like to spend time with her partner, Kayla poses the question to her potential step-mum again.

"When you meet someone and you're happy I don't think you tend to want to go out all the time," Kristy explains.

"You just have to trust that deep down I am a good person."

"We need to make sure this decision is the right one for all of us," Kayla explains.

"It could heavily impact the rest of our lives".

But with that being said Kayla beams as she gives her dad and Kristy their blessing.

"Did we just become family?" Kayla laughs.
