Teresa Giudice Quits Special Forces: World's Toughest Test Over Daughter Gia Giudice

Gia successfully held her own while weaving and jabbing against Christie, with the show's training directors calling the stars' efforts in the challenge "valiant." However, on the drive back to base camp, Gia struggled with being separated from her mom.

"Part of me wants go," the 24-year-old admitted, "but part of me is like, 'Don't do that.'"

Teresa's departure was even more unsettling for Gia given her parents' past prison sentences for fraud and tax crimes.

"My family trauma growing up was my parents went away for a little bit," Gia explained in a confessional. "So, I think that is my one trigger."

But Teresa wasn't the only season four star who left the competition during day two. Fellow Real Housewives alum Eva Marcille cracked under pressure during the milling challenge and opted to skip the exercise entirely. 

The decision signaled red flags to trainer Mark Billingham, who noted to his fellow directors, "Number 15, I don't think she's in a place for us to take forward. For her own safety really and for the course integrity."

Mark then broke the news to Eva by telling the Bravo alum, "I've watched you close. The course is gonna go like that. Physically and mentally and for your safety, I don't believe it's for you. And now, I'm going to take your armband. Do you understand what I'm telling you? Get off the course."
