Kaley Ronayne Becomes a Series Regular as Dr. Kincaid Sullivan on Season 6 of 'The Resident'

Spoiler alert: This article may contain spoilers for Season 5 of The Resident.

Fox's hit medical drama The Resident returns for Season 6, and with all new episodes comes new drama and new additions to the main cast. In July 2022, Deadline confirmed that Kaley Ronayne had gone from recurring actor to series regular for Season 6. Kaley portrays Dr. Kincaid "Cade" Sullivan on the show.

The Resident last left us with some serious relationship drama throughout Season 5. Thanks to Cade's introduction, Dr. Conrad Hawkins (Matt Czuchry) became embroiled in a love triangle between himself, Cade, and Dr. Billie Sutton (Jessica Lucas).

Season 6 will finally provide fans with answers about who Conrad ends up with. In case you need a refresher on Cade's story, here's what to know about Dr. Kincaid Sullivan in Season 6 of The Resident.

Dr. Kincaid "Cade" Sullivan was first introduced as a recurring character in Season 5. According to an October 2021 TV Line report, Cade is "a badass emergency room doctor described as an 'action heroine.'"

The outlet added, "Strong and athletic, Cade takes no prisoners but also has her own brand of no-nonsense empathy for her patients. She’s a rational problem-solver and, physically, a daredevil."

Dr. Sullivan's debut in the Season 5 fall finale leads to her prominence in the second half of the season. The Resident co-showrunner Peter Elkoff previously described Dr. Sullivan as a very reserved and secretive individual.

“She’s going to attract a lot of attention while trying to keep a low profile, which is sometimes complicated," he said. "I just imagine that the audience is going to have really strong feelings — a lot of theories and a lot of predictions."

Dr. Sullivan's first appearance in The Resident came in Season 5, Episode 10, titled "Unknown Origin," when she accompanies Dr. Conrad Hawkins and Dr. Kit Voss's (Jane Leeves) Flight Go team program to an accident site. The two worked together to save the last passenger from a flipped-over bus and began to develop a close friendship. As the season progressed, fans got to see Conrad and Cade become closer, leading to some hot-and-heavy romantic tension.

With Season 6 finally premiering, we'll finally get to see whether or not Conrad ends up with Billie or Cade or Billie. An exclusive ET report confirms that we'll find out who ends up with who by the end of the premiere.

The actress portraying Cade, Kaley Ronayne, is best known for her work as Sasha Van Dahl in the Fox crime drama Gotham and as aerospace nurse Dee O'Hara in the Disney Plus historical drama The Right Stuff.

Per Chilled Magazine, Kaley's passion for acting grew while she attended Mercy High School in Farmington Hills, Mich. After studying at Boston University, Kaley landed numerous roles. Her first significant part was as Blythe in the CW's The Carrie Diaries.

Since then, she's also starred in Public Morals, Army Wives, Quarry, Blue Bloods, and The Equalizer series. In 2022, she starred in her first major film production, The Fallen World. Her second film, This Crooked World, is currently in pre-production.
