Jan Jenning is a fictional character from the BBC medical drama Casualty, portrayed by actress Di Botcher. She first appears in the thirty-fifth episode of the thirty-second series, first broadcast on 19 May 2018. The character was created as part of the show's focus on its paramedic team, which takes hold in series 33, dubbed the "Year of the Paramedic". Jan is characterised as the strong, no-nonsense and experienced operational duty manager at Holby Ambulance Service whose steely exterior hides a caring, motherly nature. Many of Jan's stories have revolved around her relationships with other characters, particularly as a leader within the paramedic team.

The character's first major story explored her backstory through the introduction of her drug dealer son, Ross West (Chris Gordon). Writers at first withheld their connection. Jan and Ross' relationship creates tension between Jan and Iain Dean (Michael Stevenson), whose friend overdosed after being supplied drugs from Ross. He is eventually arrested and producers then introduced Jan's police officer wife Ffion Morgan (Stirling Gallacher) with the two demonstrating contrasting aspects to Jan's life. Their marriage is portrayed as strong and healthy but was challenged by the return of Ross, who gets Jan to smuggle drugs into prison for him. Writers heightened the story by having Ffion attacked and incorporating Iain's return into the plot. Botcher hoped the audience understood Jan's reasoning behind her actions, but worried some viewers may stop liking her.

A special episode, "Thin Green Lane", focusing on the pressures faced by Jan and her team aired in 2022. The documentary-style episode was improvised and actors devised their own dialogue. Executive producer Jon Sen placed Jan at the forefront of the episode and highlighted her as a leader struggling under immense pressure. Jan's next story introduces her former husband, Gethin West (Robert Pugh), and tackled the subjects of motor neurone disease (MND) and assisted suicide. Scriptwriters received support from charities, the MND Association and Dying with Dignity, to accurately portray the story and portray a balanced view on the topics. When Gethin's MND worsens rapidly, he asks Jan to help him end his life. Writers portray Jan's turmoil at deciding whether to help Gethin, but conclude the story in a special single-strand two-hander episode set in Switzerland, where Gethin attends an assisted dying clinic.

The character and Botcher's performances were well received by television critics and viewers alike. For her role as Jan, Botcher won the Drama Performance award at the 2024 Royal Television Society Cymru Awards. Sen called Jan "one of [the show's] most popular paramedics". The assisted dying story was applauded by critics and charities, with Elaine Reilly of TVTimes calling it "a poignant and intimate exploration of a difficult subject in expert hands with Di Botcher and Robert Pugh". The two-hander episode was submitted as part of Casualty nomination for the British Academy Television Award for Best Soap and Continuing Drama in 2024, which they won.

Casting In September 2017, Lucy Raffety, the new series producer of Casualty, told Sophie Dainty from Digital Spy that she wanted to increase the focus on the show's paramedic team. As the only medical drama featuring paramedics, Raffety felt it important to reflect the role, having been inspired by documentary series Ambulance and An Hour To Save Your Life. In a March 2018 interview with Emma Bullimore from TV Times, Raffety announced that actress Di Botcher had been cast in the role of Jan Jenning. The character was created in preparation for the show's focus on its paramedic team, which takes hold in series 33, dubbed the "Year of the Paramedic". Maddy Hill was also cast as paramedic Ruby Spark as part of the efforts.

Botcher was excited to join the cast. She told Sarah Ellis from Inside Soap that she was "thrilled" to be considered for the role of a paramedic as she never considered playing a paramedic herself. The actress felt welcomed by her all of her co-stars, even those who she was not filming opposite. Botcher previously appeared in the show in the series 16 episode "Life Incognito" as Louise Templeton. The actress enjoyed her experience of filming the guest role and said it remained a strong memory for her. Charlotte Salt, who portrays Sam Nicholls on the show, was excited about Botcher's casting, having been a fan of hers. She thought that Botcher would be "just the comic relief that Casualty really needs and viewers enjoy".

Development Characterisation and introduction

Jan is characterised as the strong, no-nonsense and loyal operational duty manager at Holby Ambulance Service. She is dubbed the "Mother Hen of the Ambulance Service". Jan is described as a "firm and sometimes fair" yet "cynical" person who is impressed by people doing their best. She is billed as "bold, brash and bossy", but very protective of her own team. Botcher called her character "brave, loyal and funny". Jan has a practical mindset and does not suffer fools gladly. Despite her tough exterior, she is a caring person. Dainty of Digital Spy described Jan as a "no-nonsense" and "pragmatic" woman who appears to be a "tough cookie" but is actually "a bit of a softie inside". Botcher liked her character's pragmatism; she commented, "She's got a sort of earthiness to her, a practicality and a warmth." She thought her loyalty made her someone who she would be friends with her in real life. The actress likened Jan to "a human bulldog" because she is "determined, tenacious and single-minded". She added that she is a "guarded" person. On Jan's feisty nature, Botcher opined, "Jan's got a very big heart and a lot of compassion, but she can go up like a rocket!" Jan's powerful personality comes as a shock to her new colleagues. She has been labelled an "unconventional" boss who makes an impact. Botcher opined that Jan feels confident to warn her team and "come down hard on them" because she views them like a family.

The character is established as an experienced paramedic, which has allowed her to build a wealth of knowledge. This assists Jan in deciding how to effectively treat her patients without doubt and how to identify any time wasters. Botcher characterised Jan as "a capable, caring woman, who believes in public service, and she'll go above and beyond for her patients and fellow paramedics". Through her years of experience, Jan has witnessed the various changes within the National Health Service (NHS) and has been able to keep up with the technological advances of the profession without issue. Jan is portrayed as an opinionated woman. In her eyes, the paperwork and "box ticking" exercises are the "root cause of why the NHS is struggling". Botcher enjoyed portraying a paramedic and revealed that her experience inspired her to complete a first aid training course. She liked having a balance of filming in the studio and on location, as this allows permits her to work with guest artists and the main cast alike. In particular, Botcher was a fan of working on the set of the ambulance station and called it their "home". Portraying a paramedic gave Botcher access to advice from a real-life paramedic on-set, which she appreciated as it gave the opportunity to learn as she worked. She admired the real-life paramedics and did not believe she would be capable of being a paramedic herself.

Jan is introduced in the show's 1084th episode, which is within the thirty-second series, broadcast on 19 May 2018. Her debut was publicised in a promotional trailer released on 16 March 2018. The character's first scenes involve her making "her presence known" with her new colleagues, Sam and Iain. Jan has to assert her authority quickly after they amputate a teenager's leg on a callout. This causes her to clash with Sam. Salt explained that her character becomes "really frustrated" about the treatment of her in the situation. In her early episodes, Jan is part of a stunt which Botcher deemed "impressive". She appreciated having a team of real paramedics on-set during the stunts as it helped ensure her portrayal was accurate.

Shortly after her introduction, Jan and the other paramedics are given focus through the show's "Year of the Paramedic" theme. This focus begins with Sam's death and follows the team through their grief. Raffety wanted to explore how they deal with the sudden nature of Sam's death as well as "the pressure of a front line job". Through the paramedic characters, Raffety and Simon Harper, the show's executive producer, hoped to reflect the outbreak of mental health issues within paramedics, which she found unsurprising considering they are often the first responders to "quite horrific situations".

Relationships Writers explored Jan's relationships with other characters in the show. She is established as an old friend of nurse Duffy (Cathy Shipton). Botcher told Ellis (Inside Soap) that Duffy finds Jan "outrageous" and amusing. The actress filmed her first scene on the show with Shipton. Jan was also connected to original character Charlie Fairhead (Derek Thompson), who is Duffy's husband. A "love-hate relationship" was created for the pair. The character's primary interactions are with paramedics Sam Nicholls and Iain Dean (Michael Stevenson). Their relationship is explored in Jan's early episodes. Botcher explained that Jan quickly recognises that Iain and Sam are valuable assets to her team. Salt dubbed Jan as "the third point to the triangle" in the paramedic team. She thought it created "a really nice balance". The softer side of Jan's personality was showcased when Ruby Spark (Hill) is introduced as a new paramedic. Hill noted how Jan acts like "a mother hen" and recognises that Ruby is well-intentioned, so wants her to be included in the team. Raffety thought that the paramedic team formed a "slightly dysfunctional paramedic family". Botcher enjoyed working within the paramedic team and on the ambulance station set.

A new paramedic, Fenisha Khatri (Olivia D'Lima), was introduced in 2020. As part of the paramedic team, Jan and Fenisha share many scenes together. D'Lima enjoyed working with Botcher and admitted that they had nicknames for each other. Writers used Jan's relationship with Fenisha to highlight how Jan has struggled with Iain's depression and suicide attempt. Botcher told Elaine Reilly of What to Watch that watching Iain's risky behaviour "aged Jan" and she does not want to see Fenisha follow the same path. Jan and Fenisha share a "fraught" relationship and frequently clash. Whilst Jan prefers to follow the rules and work together, Fenisha is "action-loving" and acts without thinking, something which often creates more work for Jan. Despite this, Botcher thought that her character did like Fenisha because she has "potential". In one scenario, Fenisha disobeys Jan's instructions to wait for the fire service before saving a man trapped under stage rigging. When Fenisha injures herself, Jan is furious and reprimands her, handing her an official warning. Fenisha fights back against the decision, which enrages Jan. D'Lima explained that Fenisha is feeling "a lot of hurt and anger" by Jan's decision. Botcher felt that this argument solidified Jan's reasons for being wary of Fenisha. She added that it encourages Jan to be "on the lookout" for Fenisha not following the rules. D'Lima enjoyed filming scenes of conflict with Botcher because they had fun between shooting scenes.
