The Block quitters Elle Ferguson and Joel Patfull's replacement Rachel Carr LEAVES the show

Rachel Carr and her husband Ryan replaced Elle Ferguson and Joel Patfull after they sensationally quit The Block Tree Change.

But on Monday night, Rachel made a decision to return home to Sydney to visit the couple’s three young children after just one week on the show.

During the episode, Rachel and Ryan FaceTimed their kids, who were confused by their parent’s absence.

‘We left very quickly, and we left in a way where we had to pull a lot together in a short amount of time,’ Rachel explained.

‘We have a five-year-old, a three-year-old and a one-year-old, so for them, they’re not sure of what we’re doing here. They’re not sure if it’s a good thing or a bad thing – they just know mummy and daddy aren’t here.’

An emotional Rachel explained she wanted to ‘cuddle her babies’ and said it ‘broke her heart’.

She then made a decision to travel home to Sydney for 48 hours to see her children before returning to the job site.

Rachel’s husband Ryan explained: ‘She’s really happy she made the decision to go home … the kids really needed it, and they got it.’

‘She tucked her two daughters in bed last night and they didn’t let go, so … she got some love and they got some love back.’

Ryan and Rachel replaced fashion influencer Elle and her footy star fiancé Joel, who pulled out of the competition just 48 hours into filming.

The couple made the difficult decision to leave after Joel’s mother Trish fractured her neck during a fall at her home in Adelaide.

Joel’s mother reportedly broke her coccyx and fractured her wrist.

Host Scott Cam has since accused the pair of fleeing The Block in the middle of the night and giving no explanation for their departure.

He rubbished their excuse, telling News.com.au that while Joel’s mother did injure herself before filming began, this wasn’t the excuse the couple gave for throwing in the towel.

In fact, he claims, they didn’t give any excuse at all.
