- Character Development: Gradually gains a lot of stage presence and confidence from her first audition by the time she makes the final.
- The Chanteuse: The staging and atmosphere for "Saving All My Love For You" was definitely meant to evoke this.
- Competence Zone: A rare zigzagged example. While she is older than many of the contestants in her season, she is the youngest of the Overs, and even then is only in that category because it was changed from Over 25s to 24s at super Super bootcamp. But then the other two Overs are eliminated within the first three weeks so she becomes the oldest for the last seven weeks . . . however, it is widely agreed she was at the very least one of the best in her season, regardless of age.

- Shrinking Violet: At first.
- Statuesque Stunner: She is very tall even without heels, which she usually wears.
- The Cast Showoff: She plays the piano during Week 1 for her performance of "One". Interestingly, this was the only time she did so, a rarity since contestants on these shows who can play instruments will usually play theirs just about every other performance.
- The Piano Player: She taught piano for a living prior to show.
- Aerith and Bob: The members are Kelebek, Jacinta and Jordan.
- Four is Death
- Hope Spot: Even moreso than Jiordan the week before; as it was their third time in the bottom two and they were against Taylor Henderson, a front runner who was on his first time. Instead of the judges voting them out straight away, the vote was two to one in their favor . . . until Red Foo took it to deadlock. Even then, it was still a better chance as many thought Taylor would automatically be saved, although it didn't make much of a difference in the end.

- Flower in Her Hair
- Genki Girl
- Hope Spot: Despite being on her third trip to the bottom two and being considered the likeliest to leave that week, the judges let the vote between her and Third D3gree go to deadlock . . . only for her to have the lowest votes anyway.
- Hypercompetent Sidekick: Many noted that her Save Me songs were really good and although she worked well with the songs given to her, she seemed more adept ant song choice than her mentor Red Foo.
- Go Out with a Smile
- Graceful Loser: Mouths along the lyrics to Third D3gree's performance of Thrift Shop during their "Save Me" performance against her.
- Irony: Two hours before her performance in Week 4, she started having symptoms of a heart attack, but decides to perform anyway. The song she was singing that week? Ellie Goulding's Burn.
- Kind Hearted Cat Lover
- Ms. Fanservice
- My Nayme Is: Her name is Jiordan. It's pronounced the way "Jordan" usually is and is almost never seen anywhere else as a variation.
- One Steve Limit: Subverted. While there are no other soloists named Jordan among the finalists, one of the members of Third D3gree is. He is a guy though.
- Played straight, however, in that no one of note on the show or not has the particular spelling of "Jiordan".
- Pink Means Feminine: the fake bedroom she starts out in for her cover of "Smile" is almost completely pink.
- Sad Clown: The theme of her costume for "Don't Speak."
- Scenery Porn: The entire set design for "Smile", full stop.

- Walking Disaster Area: During Week 3, the platform she was sitting on had a malfunction and didn't rotate. The following week, she sings despite having symptoms of a heart attack just two hours prior. Then, during Week 8, there's a little malfuncion for her band's platform. And yet, she carried it all with dignity.
- The Atoner: When Redfoo gaver her a no at her audition and was assigned as her mentor, this is what she had to do.
- Early-Bird Cameo: Was in the group "Good Question" the year before and made it all the way to Home Visits before getting eliminated.
- My Greatest Second Chance
- One Name Only: Her last name is Hadija.

Not necessarily dark, but a much more maturer season then past ones. Singers came from genres such as gospel, folk and soul, and a double elimination was present in this season, as well as the dreaded Five Seat Challenge. The season featured a high quality of singers, as well as two new judges and the return of an old one.
