SAS: Who Dares Wins' Shylla broke down in tears after being branded the most "distrustful" person by the other recruits on Sunday's episode.
The Channel 4 show kicked off with the instructors demanding the contestants publicly reveal who they consider to be the least trustworthy in the group.
Shylla's struggled to fight back her tears as her name was repeatedly picked by her fellow recruits.
The 33-year-old semi-pro footballer became emotional when new instructor Remi Adeleke pulled her aside for a chat.
She explained her "crippling shyness" is often mistaken for rudeness.
The recruit then broke down and covered her face from the camera as tears rolled down her cheeks.

Despite the setback, the incident pushed her to confront how a lifetime of racism has made her withdraw, sharing how her social anxiety had affected her.
The instructors admitted they wanted to get inside Shylla's head and to push her to do better.
Recruit number 18, Shylla, shared an emotional moment with Remi in a powerful mirror room interview.
"I'm so misunderstood by people, I struggle to start a conversation - I've always been that person who speaks when they've spoken to, she told Remi and Rudy Reyes.

"Just growing up as a Black girl, I used to get stereotyped as the angry black girl. And I’ve just always been made bad, slapped with emotions.
"So I just found it easier to not express myself, just gradually just be quiet and not react to things.
"Because whenever I react, it’s like someone would tell me to calm down before I even said two words.
"The ugly Black girl was such, and just never having any confidence in myself."
Remi asked her to hold her arm out and pointed out they are both the "same colour".
He explained that he is still judged by others but doesn't allow it to affect him.
"The last thing I’m going to do is allow that to affect the rest of my day. Because when I do that, I’ve allowed racism to win. You understand that?," he told Shylla.
"Here, it’s not about race. It’s not about gender. It’s about performance. And you have performed top-notch."
Shylla revealed that she suffered from selective mutism as a child and only spoke to those close to her.
She explained that she's never had a serious relationship in her adult life - but was ready for that to change.
Viewers were heartbroken as they watched Shylla open up about her past.
One wrote: "Oh give number 18 a hug, so proud of her. #SASWhoDaresWins"
"#SASWhoDaresWins Come on Shylla you can do this. That was such an emotional raw moment between you and Remi, another posted.
A third tweeted: "18 you are a superstar, that reduced me to tears. #SASWhoDaresWins"
A fourth echoed: "You should feel proud of yourself Shylla."
"Absolutely love #18, she's a slow burner and about to light up the show," one viewer commented.
