Vidalia

"Vidalia" is a minor character who made her debut in "Story for Steven" in a flashback, and reappeared in "Onion Friend" in person.

Debut (past)
Vidalia has knee-length, light blonde hair that seems to spike around her face and at the top of her head. She, unlike most female characters, wears light magenta/pale pink eyeshadow. She wears white boots, and high-waisted, gray jeans that are torn on the knees. Vidalia also wears a dark leather jacket with spikes on the shoulders, and it appears to have a belt hanging off of it. Her shirt is pale blue.

Current
She is much older and wears her hair in a short, thick bob which closely resembles a Vidalia onion. At home, she wears a mint green shirt with rolled up sleeves over a white t-shirt and overalls with rolled up pant legs, as well as red slippers.

Personality
In "Story for Steven", she is shown to have an apathetic personality. She shows barely any concern for anything or anyone around her.

In "Onion Friend", she shows much more emotion than she did before. She is also very empathetic, listening to Amethyst talk about how Garnet and Pearl's fight has been affecting her. She acts like a truly motherly figure to her sons, and even expresses some motherly affection towards Amethyst. She is also innovative, claiming that her sons have to express themselves, allowing Sour Cream to do his DJing. Warm and a true artist, she still considers herself a troublemaker and a 'bad girl'.

"Story for Steven"
Vidalia is first shown when Greg Universe runs to his van to retrieve a T-shirt for Rose Quartz. Marty introduces her to Greg, and she is not seen after.

"Onion Friend"
Vidalia is revealed to be longtime friends with Amethyst, mother to Onion (whose father is Yellowtail) and Sour Cream (his father being Marty), and married to Yellowtail. Amethyst is revealed to have modeled for her paintings in the past.

Greg Universe
Though she does make a presumably sarcastic remark about his van, she claims "he used to be super hot" in "Onion Friend" and Amethyst states that herself, Vidalia and Greg used to be a group of close friends, but the two separated from him because "he wasn't cool enough".

Marty
"I don't know where that fool is! Don't care either." Marty hooked-up with her when he and Greg were playing in Beach City. They attended a party with her friends together. Their relationship seems to have not been anything serious but rather a cheap fling, as Marty is quick to abandon her when he and Greg have to leave Beach City to continue the tour -- which is a stark contrast to how Greg felt towards Rose.
 * In the background of one scene in "Onion Friend", there is a picture of Vidalia and Amethyst in a photobooth. In the photo, Amethyst shapeshifts into Marty and makes a rather unflattering impression of him, which seems to greatly amuse Vidalia.

Amethyst
It is unknown when they met but Vidalia and Amethyst became very close when they were hanging out with Greg. She was so inspired by Amethyst's free-spirited nature that she even began painting pictures of her at one point with her modeling, and again years later. They reconnect in "Onion Friend". They seem to be influential of eachother, even Vidalia mentioning that Amethyst inspired her, and was the reason why she started painting her again after they lost contact with each other. They took a lot of pictures, which implies they spent a lot of time together before the events of the show, and at the end of "Onion Friend", it is implied they will start talking to each other again.

Yellowtail
In the episode "Onion Friend", it is revealed that she married Yellowtail after she left Marty.

Onion
After marrying Yellowtail, Onion was born. Vidalia loves her son greatly, so much that she even encourages his expressive nature.

Sour Cream
Her only son with Marty, Vidalia loves Sour Cream nonetheless. She encourages his love of being a DJ, even to the dismay of his stepdad's wishes.
