Tonight, Josh and Austin proclaimed, "honesty is important" when confronting Andy and Ruby over the comments they made about Karito and Ian's instant restaurant.
However, reality TV podcast Real Talk with Holly & Ali has exclusively revealed the Christian home-schooled brothers are keeping an enormous secret themselves.
In fact, their secret is so big, that to this day they STILL haven't fessed up to their fellow teammates about it even after being confronted numerous times during filming.
"I don't know how much we can speak about this" Ibby told Real Talk.
"We had lots of fights with Josh and Austin. Me and Romel we were really looking for things to try and hold them for something because we knew that there was something about them that's not quite right about them."
It was Romel who noticed something about Josh and Austin, which led to some suspicions being confirmed.
"I thought these guys just aren't adding up so I did some research," he explains.
"I made a couple of calls and we found out some information and we confronted them and we got nothing, absolutely nothing.
"When we tried to bring it to them, we confronted them, they would just deny it.
"You could see it in their face that they were so uncomfortable but they wouldn't say anything."
So what is Josh and Austin's shocking secret they've tried to hide?
