Jackie is a very laidback and kind girl who is shown to enjoy and have a talent for skateboarding. She is initially unaware of Marco's crush on her until the events of "Sleepover", and she is generally cordial towards him when they interact.

On one occasion when Marco broke her skateboard, she barely displayed any anger towards him.
In "Bon Bon the Birthday Clown", Jackie is stated to have an interest in history books and mellow music, and she admits to admiring Marco's never-give-up attitude.
In "Starcrushed", Jackie is shown to drop her trademark coolness and act rather dorky around Marco; she tells him to try and read her mind, and they feed each other pizza nuggets. She is also visibly shocked when Star confesses to having a crush on Marco in front of everyone, staring in surprise at the revelation.

In "Just Friends", Jackie attends a Love Sentence concert with Star and Marco. When Marco feels like he's not fun enough to hang out with the two of them, Jackie assures him that she likes hanging out with him. She and Marco kiss twice at the concert. In "Starcrushed," Jackie tries to get Marco's mind off of his and Star's strained relationship after the events of "Face the Music", and she also acts more casual and dorky around him.Sleepover" and "Just Friends". In the latter episode, the two share a love for the Love Sentence. However, Star becomes jealous of her growing relationship with Marco, and she even uses a spell to spy on them when they go on their first date.
