Emotions were high during the first episode ofMasterChef Australiaon Sunday night. A fresh batch of amateur cooks filled the kitchen, but there was one familiar face among them - Brent Draper.

Fans will remember the now 32-year-old left the competition in 2021 to focus on his mental health.

"I've just got nothing left," he told judges at the time.

Returning to the kitchen on Sunday night, Brent said "It's not about the stumble, it's about the comeback." And what a comeback - he hit the hibachi and impressed celebrity judge Jamie Oliver with a Tamarind Glazed Pork Chop with miso carrot puree and peanut chilli salad. "I love the way you are thinking fatty pork, tangy, tart-tamarind there's real intelligence there. Delish," said Oliver when tasting the dish. During the episode, Draper said he was nervous being back in the kitchen. "It's a funny feeling walking my food back up to the judges again," he said.

It was emotional viewing for many fans, as we watched host Jock Zonfrillo who passed away suddenly on May 1.

"This season of MasterChef Australia was completed in March 2023 and we would like to dedicate it to Jock and his family," a tribute at the beginning of the episode read. "Please enjoy it as a celebration of his work, life and irrepressible passion for food."

Jock was an important mentor to Draper. When Brent decided to leave the competition in 2021, Jock pulled him aside for a chat, giving Brent his worry beads. Writing on Instagram last week Brent said "Jock, the world is now poorer without you in it mate." "They say you meet people in life for a reason, a season or a lifetime," he wrote. "What I know is that Jock Zonfrillo came into my life for a reason, although I wish it could have been for a lifetime." "The impact that Jock made on my life on TV is something I'll never forget and I could never thank him enough for, but it's the impact he made afterwards and off-camera that will stay with me forever. Speaking toMamamiain 2021 Brent explained why he decided to leave the show. "It probably [started] way before the show," Brent toldMamamia. "And you know, as men, not really dealing with things, [I was] sort of brushing over things."

During filming, a few things made it worse.

"My mum had a bit of a health scare beforeMasterCheffilming and a passing in the family during, then quarantine twice. But one of the biggest things was homesickness. Just missing out on little things that [my two-year-old son] Alfie was learning," Brent said.

"One of the biggest [filming] stints we did was about seven weeks, I think. And quarantine, it's not a great place for people - no fresh air, not great food, no human interaction and 14 days is pretty long."

"It [my mental health] just started to spiral. There's obviously pressure in the kitchen - that's what makes it so great - but I didn't deal with things and it snowballed," he said.

Brent's anxiety manifested in physical symptoms. He started feeling unwell in his stomach, prompting him to google his symptoms. He thought he had liver disease.

"My mind just couldn't get out. I wasn't thinking logically anymore," he toldMamamia.

While other people in his life knew it was anxiety, he couldn't look past the physical symptoms.

"My wife and other people outside me, they could see it was anxiety, and they kept telling me, but I was like, 'you're not feeling what I'm feeling. I'm sick.'

"I went to the doctors, I went to acupuncture, and I ended up in an emergency. It would help for a little while and then it would cripple me again. Then I'd have sleepless nights and panic attacks during the middle of the night - that's just the loneliest place," he said.

While Brent leftMasterChefto focus on his mental health, he didn't believe the show played a large role in his mental health declining.

"It just heightened everything for me," he said. "The pressure's there but I wasn't dreading the cooking. I was actually dreading the nighttime."

"Jock actually rang me to tell me that [moment] was real, that was me and him, 100 per cent," Brent toldMamamia.

"I knew that because when I was in that moment, I could see the pain in his eyes. He's obviously very open about his anxiety and how he deals with it so he could see that I was not well a few cooks, probably a few weeks before [I left]," he said.

Brent also made "lifelong mates" during the competition - contestants Justin, Amir and Pete - who helped him through this tough period.

"I made lifelong mates," he said. "They were the guys that were talking me off the ledge (not literally), really helping me out and at the same time, they were going through some struggles too.

"We were there for each other and that was really good."
