True to her word, Jelissa truly ground the contestants down to the bone, making her kind and gentle teaching style seem like a joke.
The number of times she repeated the words 'just one more take', 'can you sing it this way', 'I promise, just one more time', before making a contestant repeat a single line of the song close to 50 times single-handedly built calluses on Ari's ear, and made him look at her in a different light.
Despite her gentle demeanor and sincerity, she was truly a perfectionist and completely dedicated to getting the perfect sound out of the contestants.
When she saw different contestants getting frustrated in the booth, she would play back their first take and the latest take so that they could understand the difference and hear the improvement, which seemed to help motivate them to do better.
