Rochelle's Journey Through The Tower
On Floor 6 'Toxic Treats', Rochelle received no votes as Saboteur and she voted for Frankie because "She was always, always telling us to go and I thought it was her". Tia also voted for Frankie, while Montell voted for Nikica, and Aimen, Frankie and Nikica all voted for Montell. The real Saboteur was Montell. As the team failed, the Unfortunate with the most votes (Montell) got trapped.
On Floor 5 'Freaky Factory', Rochelle received no votes as Saboteur and she voted for Aimen because "Every time I went to put an egg in, he kind of took one from mine and cracked it". However, the rest of the team voted for Frankie (voted by Nikica and Tia) and Tia (voted for Aimen and Frankie). The real Saboteur was Nikica. As the team failed and Frankie drew the short straw, she got trapped.
On Floor 4 'Snake Attack', Rochelle was chosen as the Saboteur. She had to make the team fail by getting them bitten by the snake three times. Rochelle successfully sabotaged the challenge, getting 3 wrong guesses in a row, and no right guesses. She received three votes as Saboteur - one from Tia because "The second time Aimen put his hand in she said 'I don't know, I don't really have a clue'", one from Aimen because "Firstly she got my hand dirty. Secondly because... it's her", and one from Nikica because "She suggested the last two and it was actually wrong and she wasn't quite sure what she was saying". Rochelle voted for Tia as the Saboteur because "She never made much contribution to where was the snake". As the team failed and Rochelle was detected as the Saboteur, she got trapped.
When The Voice asked Rochelle "Why do you think the others voted for you?", Rochelle said "I made the wrong decisions and I was hesitant".
