Sam Nicholls
Sam Nicholls is a fictional character from the BBC medical drama Casualty, played by Charlotte Salt. She first appeared in the twenty-sixth series episode "Mea Culpa", broadcast on 15 October 2011. Sam is a former major in the Royal Army Medical Corps, who joined the Holby City Hospital Emergency Department on a nine-month secondment, later becoming a Specialty registrar in emergency medicine. Salt was contracted for a year and she spoke with army medics to help her prepare for the role.
Sam is portrayed as being a fearless, headstrong, competitive "action girl". Salt said Sam is also haunted by her time in Afghanistan. A few months after her arrival, it emerges that Sam is married to fellow ED doctor Dylan Keogh. The estranged couple struggle to stay professional, especially when Sam files for divorce. A storyline arc focusing on whether Sam used excessive force on a patient began in early 2012. A formal complaint is made against Sam, resulting in a General Medical Council hearing. The character's backstory is also explored further in a special Red Button episode set in Afghanistan.
Sam was later given a love interest in Tom Kent. The couple's relationship is tested by her friendship with Iain Dean, but they later marry and make their last appearances in twenty-eighth series episode "Away in a Manger", which aired on 14 December 2013. On 25 April 2017, it was announced that Salt had reprised her role as Sam. Salt said she was "thrilled" to return and was excited about telling Sam's story once again. Sam returned on 23 September 2017, as a paramedic. During her second stint, Sam has a brief relationship with nurse Jacob Masters. When Salt wanted to leave the show once more, producers decided to kill her character off, and Sam's final scenes aired in episode 1094, broadcast on 18 August 2018. Sam was well received by critics and viewers.
Casting
On 30 September 2011, the BBC announced actress Charlotte Salt had joined the cast of Casualty as "ambitious army medic" Sam Nicholls. Her casting was announced alongside that of Oliver Coleman, who joined as paediatric doctor Tom Kent. Series producer at the time, Nikki Wilson, commented that the character would be exciting and intriguing when she made her debut in October. Salt was initially contracted for a year, and she admitted that joining a long-running drama felt "quite scary" to her. To prepare for the role, she spoke with some army medics, including one who had worked on helicopters in Afghanistan. Salt also had to train for the various stunts that Sam was a part of, but she found the medical jargon to be the toughest aspect of the role. She stated, "It wasn't easy getting my head around it all at the beginning but it does get easier with practise!"Development
Characterisation and introduction
Ahead of her introduction, Sam was billed as being "fast-living, fearless and fiery" by the BBC. Salt later said Sam is "feisty, sure of herself and rubs people up the wrong way." She also described her as being competitive and someone who says what everyone else is thinking. Salt dubbed Sam "Casualty's answer to Lara Croft!" She told Patrick McLennan of What's on TV that Sam was a tough, "action girl", who was keen to save everyone, but she did not want her to seem like a "war machine". The actress also told McLennan that Sam was a fun character to portray, and hoped viewers would like her "energy and enthusiasm." Salt did not want Sam to be too likeable, as she thought that would be boring. Sam is a former major in the army, who comes to Holby on secondment, after serving in Afghanistan. Salt stated that Sam would find it hard to adapt to working at Holby, after being in a war zone, and that she would be haunted by her time over there. Salt also said, "Because the work is so traumatic you need a break. That's why my character is spending nine months with the NHS."Sam turns up to work at the hospital a day early, and decides to go out with paramedics Dixie Dixon and Jeff Collier. They attend to Father Vincent McConnell, a priest who has been attacked by Paul Caffrey, as he believes the priest abused his brother. Salt told Katy Moon of Inside Soap that Sam approaches the scene "in true Army style" which annoys Dixie and Jeff. Sam manages to deal with an angry Paul, but he later uses his vehicle to ram the ambulance, causing it to overturn and injure Sam. Salt called Sam's first episode "fantastic" and "very exciting". She also explained that the situation showcases Sam's selfless side, as all she cares about is saving lives despite being injured herself. Salt said Sam manages to antagonise her colleagues, especially Nick Jordan. She later added that Sam would clash with Zoe Hanna, as she does not get on well with women, having come from a job that was dominated by men. Salt enjoyed portraying the scenes between Sam and Zoe, and joked "I don't want to be nice ever!"
Marriage to Dylan Keogh
Ahead of her first episode, Salt teased Sam's connection to someone in the ED, saying the viewers would be surprised by their identity. It soon emerges that Sam is married to fellow doctor Dylan Keogh and that they were estranged. Beck explained that Sam and Dylan had a Las Vegas wedding, which he thought showed "some idea of the longevity of the relationship". While Dylan is "mortified" that his personal life is being discussed by his colleagues, Sam believes he should get over it. Before they can discuss things, Sam is called out to attend to victims of a chemical spill. Sam deliberately puts herself in danger to spite Dylan and get his attention. Zoe is hurt to discover that Dylan is married, and Salt pointed out that Zoe had been flirting with Dylan, but he was unaware of it. She continued, "Sam's not going to be okay with that. Even though she and Dylan aren't together any more, she still loves him in a way. Tension's building – it's going to get messy."Sam and Dylan are brought together when Sam receives a call to rescue two dog walkers, who have fallen into a cave. She realises to her "dismay" that the only other doctor who can abseil is Dylan. As they descend into the cave, Sam and Dylan try to keep their relationship professional, but soon begin to argue about their failed marriage, placing themselves and their patients in danger. Speaking to Sarah Ellis of Inside Soap, Salt said that being trapped in the cave with Dylan was Sam's "worst nightmare" and that the situation caused all of the issues about their marriage to come to a head. The couple have a hard time treating Amanda Franks and David Hooper, but when David's condition worsens, Sam and Dylan put their problems aside to help save him. Salt added that Sam does not like tight spaces, but she manages to hide it well. In the end, she and Dylan manage to bond when they realise their argument is not important.
Sam secretly files for a divorce, but is "horrified" when Dylan receives the solicitors' letter at work, before she can speak to him about it. Sam asks Dylan if they can talk after their shift, which makes him believe that she wants a reconciliation. Dylan later tells Sam that he has booked a table at a restaurant, and she realises that he thinks they are going on a date. As their divorce proceedings begin, Dylan and Sam's relationship breaks down and they struggle to work together. When they are called upon to treat a patient together, Dylan decides to hand the patient over to Sam, as he refuses to have anything to do with her. Nick Jordan notices their behaviour, and he tells Sam to find a way to work with Dylan. However, when Dylan begins belittling her, Sam decides she has had enough and contacts her former commanding officer to ask if she can return to the army. Sam is denied a return to the army, forcing her to remain at Holby. Dylan's attitude towards her grows meaner, but she tries her best to ignore it and get on with her work.
Dylan refuses to sign the divorce papers, but insists that he wants Sam to leave Holby, prompting Salt to comment that Dylan was "confused by his emotions". She also thought that Dylan's refusal to sign the papers was because he knew that was what Sam wanted. Sam and Dylan's bad relationship affects their work to the point that a patient's life is put at risk, while Dylan is being particularly "vicious" to Sam. Salt said that Sam accepts the way Dylan treats her because she knows he is hurt. The actress also thought Dylan was hoping they might reconcile, but Sam no longer wanted to be married to him. Salt continued, "she doesn't want him to hate her or to lose him as a friend. She's almost reaching out to Dylan for a helping hand. It's really quite moving." Sam and Dylan eventually sort things out between them when Sam reveals her reasons for coming to Holby, her selfishness, and why she kept her "baggage" a secret.
Assault and GMC hearing
One of the character's more notable storyline arcs began in early 2012 when Sam saves Dylan from being attacked by patient Keith Parr. She puts Keith in a headlock, which fractures a bone in his neck. Salt explained to Sarah Ellis of Inside Soap that when Sam see Dylan's life under threat, her first thought is to protect him. Producer Nikki Harris said the storyline would "bubble under for the rest of the series" and would raise the issue of whether Sam used excessive force. The situation also affects Sam's colleagues, who feel that they have to support her. Keen to avoid having legal action brought against the hospital, Zoe Hanna asks Sam to meet with Keith and apologise. With the assault having been caught on CCTV, Salt pointed out Sam was in serious trouble. However, she refuses to meet with Keith as she feels that it was not her fault. Zoe asks Dylan to persuade Sam to change her mind, but he is hesitant to get involved. While treating a rape victim who defended herself against her attacker, Sam realises "the gravity of her own situation" and visits Keith, but she ends up accusing him of attacking Dylan. Salt told Ellis that Sam fails to realise that she cannot lash out at people without consequences.Nick later informs Sam that Keith is filing an official complaint against her, and he advises her to keep her head down. A lawyer for the General Medical Council investigates Keith's complaint and Sam's colleagues are asked to give statements about the incident. Dylan tries to avoid giving his, while Zoe learns that she will be called as a witness. In March 2012, Daniel Kilkelly of Digital Spy reported a special Red Button episode titled "Under Fire" would explore Sam's time in Afghanistan, and the events that led to her arrival at Holby. Producers told Kilkelly that the episode would explain Sam's "brusque bedside manner and brave but impulsive decision-making". The episode is set in Camp Bastion and explores Sam's time working on a MERT helicopter, alongside Corporal Iain Dean, who she is having an affair with. While Sam is treating patients from a suicide bombing, Sam is alarmed when it seems one of them is reaching for a device and she makes "a split-second decision which has life-changing consequences." The special was filmed at an army barracks in Cardiff. Salt enjoyed exploring Sam's past, and commented that Sam and Iain's affair "was just a moment of comfort – it's a different world out there in Afghanistan."
The following month, Sam is brought before the General Medical Council and accused of using excessive force to restrain Keith. Salt explained that if Sam is found guilty she would lose everything, as she would no longer be allowed to work as a doctor. When Sam learns that Zoe will be testifying against her, she is "livid". She then decides to fire her legal team and represent herself. Salt thought it was "madness", but said that Sam needed to feel that she was in control of her own fate. During the hearing, Dylan is also called to the stand, where he defends Sam and finds it hard to hide his feelings for her. However, Dylan is shocked when Iain reveals that he and Sam were romantically involved, and that Sam has been affected by the events in Afghanistan. Salt told Ellis that Dylan is "very hurt" that Sam never confided in him about the things that happened while they were together. She continued, "The lose all sense of professionalism, and end up bickering in the middle of the hearing room!" Towards the end of the hearing, new evidence emerges that clears Sam's name. Salt believed that Sam would be changed by the whole situation, saying she would be more cautious.
