Celine Aurora Tiana McQueen, played by Sarah George, made her first on screen appearance on 10 November 2014. The basis for the character was announced on 3 May 2014, whilst the character name and casting was announced on 26 August 2014. The character made a previously unannounced departure from the soap opera on 5 December 2016, when she was murdered by her ex-boyfriend, Cameron Campbell (Cameron Moore), becoming the fourth member of McQueen family to die on the show since Tina Reilly in 2008, Carmel McQueen in 2014 and Gabriel McQueen in 2015. Celine is a nurse and is billed as being in touch with her spiritual side and nobody's fool.
Celine arrived for her sister Porsche McQueen's (Twinnie Lee Moore) wedding to Cameron's brother Lockie Campbell (Nick Rhys). She was on the train when it crashed, but was not badly injured. She and her cousin Theresa McQueen (Jorgie Porter) found Maxine Minniver (Nikki Sanderson) after the crash.
Following the train crash, Celine helps out and becomes a nurse at Dee Valley Hospital. She helps Jason Roscoe (Alfie Browne-Sykes) when he was admitted to hospital after collapsing, and discovers that he has body image issues. Celine confesses that she has battled body image issues since she was Jason's age, however, her advice falls upon deaf ears as Jason refuses to believe he has a problem. Celine also becomes attracted to Jason's older brother Ziggy Roscoe (Fabrizio Santino) and the pair go on a date, although Ziggy prefers Celine's colleague, Tegan Lomax (Jessica Ellis). Celine gets into trouble at the hospital when she takes the blame for Tegan performing a blood transfusion on her own daughter despite being a student nurse, but Tegan later admits the truth and Celine is cleared. Celine and Ziggy sleep together, and Tegan is heartbroken to discover them. Celine and Tegan eventually make up and Tegan confides in Celine when she discovers that her daughter, Rose Lomax, is not her biological daughter. Darren Osborne (Ashley Taylor Dawson) attempts to flirt with Celine, although she rejects his advances.
When treating Cameron Campbell (Cameron Moore) for an infection, Celine becomes attracted to him, and she is delighted when he asks her out on a date. However, Cameron is secretly still in love with Tegan's older sister, Leela (Kirsty-Leigh Porter), who is engaged to Ziggy. Cameron later asks Celine for help when he wants to make Leela jealous, and she reluctantly agrees. When this does not work and Leela does not seem jealous, Cameron and Celine sleep together. However, Cameron reads a text message on Celine's mobile phone which reveals that Ziggy and Tegan have feelings for each other, resulting in Cameron confronting Tegan the following day. Cameron later finishes with Celine completely. Celine is now a senior nurse after blackmailing Dr. S'avage. In April 2016, it is revealed that Celine attempted to kill Pete Buchanan (Kai Owen), who was thought to be a victim of serial killer Lindsey Butterfield (Sophie Austin). Celine is later pressured into marrying her aunt, Myra's (Nicole Barber-Lane) fiancé, Diego Salvador Martinez Hernandez De La Cruz (Juan Pablo Yepez), in an attempt for Diego's mother, Juanita (Jacey Sallés) to give the family £5 million. However, this ultimately ends Celine's blossoming romance with Jesse Donovan (Luke Jerdy). This stresses Celine immensely, as she feels guilty for lying to everybody she knows. On the day of the wedding, Myra declares her love for Diego in front of Juanita, ruining the scam, and so Celine declares her love for Jesse, and they begin a relationship.
Celine discovers that Cameron started the fire in the wooden maze at the "Halloween Spooktacular", which killed Nico Blake (Persephone Swales-Dawson) and Joe Roscoe (Ayden Callaghan), after viewing the footage on a video camera. Celine confronts Cameron, however he threatens her with the information he has about her attempting to murder Pete. Celine and Cameron both promise not to say anything. This causes Jesse to end their relationship because everyone believes that he started the fire. Celine is riddled with guilt and decides to tell the police what Cameron did. Desperate to keep the truth from being revealed, Cameron holds Celine hostage in the same shack where he had previously held Lockie captive. Cameron confronts a terrified Celine after he finds a voicemail from Jesse on her phone, leading to him believing that Celine has told Jesse that he started the fire. Cameron apologises to Celine for doing what he's about to do, she begs Cameron to let her go but he picks up some rope and tearfully murders Celine by strangling her to keep his involvement in the fire a secret. He then disposes of her corpse and her belongings. When Tegan and Cleo become suspicious, Cameron texts them from Celine's phone saying that she was going backpacking to "find herself" and that she would be abandoning all forms of technology. Celine's sister Cleo McQueen (Nadine Mulkerrin) later sees that Cameron has given Celine's ring to Leela as an engagement ring; but believes Cameron's story that he bought it at the Emporium, and assumes Celine sold the ring to finance her travels.
In January 2017, Cameron was later arrested for the murder of Celine, Danny and Sam Lomax, Lockie Campbell, Ziggy Roscoe, Joe Roscoe, and Nico Blake.
