Reference excerpt

Guy Self is a fictional character from the BBC medical drama Holby City played by John Michie. He first appeared in the sixteenth series episode "Sink or Swim", broadcast on 26 November 2013. Guy is a consultant neurosurgeon and Holby City Hospital's chief executive officer (CEO) until he resigns from his CEO position. The character also appeared in Holby City's sister show, Casualty. Guy departed in the nineteenth series episode "Song of Self – Part Two", but returned for a nine episode guest stint later in the series. Michie has since reprised the role on three occasions: for one episode in 2018, ten episodes in 2020, and one episode in 2022.

Creation and casting On 12 July 2013, it was announced that actor John Michie had joined the cast of Holby City as new consultant neurosurgeon Guy Self. Of his casting, Michie said "I'm absolutely thrilled to be joining the cast of Holby City and I'm looking forward to taking on a new challenge. My mum was a nurse and always wanted me to be a doctor not an actor so finally half her wish has come true!" Executive producer Oliver Kent commented that Michie would be involved in some "explosive" storylines following his arrival. Michie was initially contracted for a year and he made his first screen appearance as Guy on 26 November 2013. To help him prepare for the role, Michie met with a surgeon and watched him operate. The actor told a reporter for the BBC that he spent some time observing the consultant's demeanour, which was "friendly and chatty, but with an unspoken authority". Michie tried to bring those aspects of the consultant's personality to his portrayal of Guy. Michie called the medical terms "complex", but said that having medics in his family made learning the terms easier. He also admitted that he was not squeamish and enjoyed the realism achieved by the prosthetics department.

Development Unpredictable, assertive and driven, Guy Self is a leader who demands excellence from others. He is a spontaneous, original thinker who seldom lets rules dictate his lust for work and life. In an interview published on BBC Online, Michie explained that Guy is committed to being a neurosurgeon, which makes him ruthless at times. His job gives him "incredible self-belief", although he does not always get things right. Michie thought Guy had a tendency to push himself and his colleagues too hard. He added that women are one of Guy's weaknesses. In August 2016, Guy's mother Valerie Sturgeon (Brigit Forsyth) was introduced, leading to further exploration of the character's background. Michie was pleased to receive the storyline, as he believed it would finally show the audience why Guy is the way he is. The actor told Inside Soap's Laura-Jayne Tyler, "Hopefully people will have more sympathy for him, rather than see him as a total bastard!" When Guy's mother Valerie is admitted to Darwin, she meets her granddaughter Zosia March (Camilla Arfwedson) for the first time. Zosia always assumed Valerie was dead. Michie explained that Guy deliberately kept his mother away from Zosia, as she subjected him to physical and mental abuse when he was a child. Guy eventually breaks down and tells Zosia the truth about his childhood with Valerie. Michie said filming the scenes with Arfwedson was "a little bit disturbing", as he had to find something in his personal life that made him feel the same as his character.

Departure The character departed the show on 15 November 2016. Guy's exit storyline saw him resign from the hospital. Shortly beforehand, he learnt board member Tristan (Jonathan McGuinness) had attacked his daughter Zosia. Guy had been working with and relying on Tristan to get his neuro centre built. Michie told Allison Jones of Inside Soap, "Guy is very vulnerable, like a cornered animal, and he isn't really thinking straight. The centre has been his dream – and for 20 years, he's compromised a lot of his personal life to get it built." Michie said Guy is tempted to let Tristan die when he ends up on his operating table, but his "medical ethics" kick in and he saves Tristan by stopping the bleeding in his brain. Guy decides to report Tristan's attack on Zosia to the police, but Tristan blackmails Guy by threatening to reveal his suicide attempt. However, Jac Naylor (Rosie Marcel) reports Tristan instead and he goes to the press about Zosia. Guy "cracks" and he trashes his office. He then realises that he needs to leave the hospital for the sake of his mental health. Michie enjoyed filming Guy's last episode and liked how his character made his exit. He thought Guy could make a return in the future, even though things are resolved with "a good ending" in the episode. He said, "I think it's the right time for him to go, but the door has been left open. So maybe he could come back one day and be even worse, or perhaps he'll come back and resolve stuff – who knows?" Michie found it sad saying goodbye to the show and his co-stars, but he added that it was also an exciting time, as he liked moving on to new roles.

Worked examples

Example 1 — a first encounter with Guy Self

Start with the simplest possible case. Write down what Guy Self claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Guy Self before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Guy Self ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Guy Self

In research: Guy Self appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Guy Self in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Guy Self is common in secondary-school and first-year university syllabi. It links to neighbouring topics British male characters in soap operas, Fictional neurosurgeons, Fictional surgeons, so understanding it makes those chapters shorter.
In everyday life: Look for Guy Self outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
