Television

[edit]

Ryan Sinclair is introduced in the eleventh series premiere, "The Woman Who Fell to Earth".

Ryan is a 19-year-old living in Sheffield, England who is training to be an electrical engineer while working part-time as a warehouse worker. He was raised by his paternal grandmother, Grace O'Brien, who recently married his step-grandfather, Graham O'Brien. Grace worked as a nurse, and met Graham while he was undergoing chemotherapy for cancer, about three years before they met the Doctor. Ryan and Yasmin Khan were in primary school together, though at the time they didn't know each other very closely.

Ryan has dyspraxia, a coordination difference that impacts his motor skills. Though his symptoms are relatively mild and high-functioning, it affects his sense of balance to the point that he finds tasks like riding a bicycle extremely difficult.[1]

His father, Aaron, a marine electrical engineer, made an appearance in the 2019 New Year Special. Aaron has been absent most of Ryan's life since the death of his mother, and was also absent for Grace's funeral.

Other media

On 22 October 2017, it was announced that Cole had been cast as a companion in the eleventh series of Doctor Who, and would appear alongside Jodie Whittaker in 2018.[3]

On 26 September 2018, following the premiere of The Woman Who Fell to Earth, the fact that Ryan would have dyspraxia was officially revealed by the media. Showrunner Chris Chibnall explained: “It's a relatively common thing among kids, so I think it's important to see that heroes come in all shapes and sizes.” Considerable research was undertaken with the Dyspraxia Foundation to ensure an accurate portrayal of the condition.[4]

Cole departed the role in the special "Revolution of the Daleks".[5]

Ryan Sinclair is a fictional character in the British science fiction television series Doctor Who, introduced as a companion to the Thirteenth Doctor in the eleventh series.[1] Portrayed by actor Tosin Cole, Sinclair is depicted as a young man from Sheffield, England, working in a warehouse while studying to become a mechanic, and living with his grandmother Grace O'Brien and her husband Graham, his step-grandfather.[1] He first appears in the episode "The Woman Who Fell to Earth" (2018), where he joins the Doctor's travels following Grace's accidental death during an encounter with an alien assassin, marking the start of his adventures across time and space alongside Graham and fellow companion Yasmin Khan.[2] Sinclair's character arc centers on personal growth, particularly overcoming the challenges of dyspraxia—a developmental coordination disorder that affects his motor skills and self-confidence, notably his inability to ride a bicycle, which becomes a recurring motif symbolizing his journey toward independence.[1] Throughout series 11 and 12 (2018–2020), he faces iconic threats including the Stenza, Daleks, Cybermen, and the Judoon, contributing to resolutions such as aiding in the defeat of the Morax in "The Witchfinders" and reconciling with his estranged father, Aaron, during a Dalek invasion in "Resolution."[1] His time in the TARDIS fosters family reconciliation, as he builds a stronger bond with Graham and supports the Doctor's team dynamics, while grappling with themes of grief, identity, and resilience.[1] Sinclair departs from the TARDIS crew in the 2021 special "Revolution of the Daleks," choosing to remain on Earth with Graham to pursue a more grounded life, though he returns in later audio adventures and other tie-in media.[3][4] Cole's performance earned praise for authentically representing dyspraxia and bringing emotional depth to the role, contributing to Sinclair's status as a relatable and memorable companion in the show's modern era.[5]

Fictional character biography

Early life and family

Ryan Sinclair, born and raised in Sheffield, England, was 19 years old at the time of his introduction in the series. He worked part-time as a warehouse operative while training to become a mechanic, balancing his studies with everyday responsibilities in his local community.[6][1] Sinclair was raised primarily by his grandmother, Grace O'Brien, a dedicated nurse, and his step-grandfather, Graham O'Brien, a retired bus driver, after his mother left the family. His father, Aaron, worked abroad as a marine electrical engineer, which limited his involvement in Ryan's upbringing and contributed to a sense of familial disconnection. This household dynamic provided Sinclair with a stable yet emotionally complex foundation, marked by the supportive yet imperfect relationships with his grandparents.[6][7] Sinclair had been diagnosed with dyspraxia, a developmental coordination disorder that significantly affected his daily life. He struggled with motor skills, most notably failing to learn how to ride a bicycle despite repeated efforts, which led to persistent coordination challenges in physical activities. These difficulties often resulted in emotional frustrations, including being taunted by peers as "the boy who can't," fostering a deep-seated sense of inadequacy that he carried into adulthood.[6] This condition would later influence his resilience during more extraordinary circumstances.[8] A pivotal event in Sinclair's early life occurred in "The Woman Who Fell to Earth," when Grace O'Brien was fatally electrocuted while attempting to save others from an alien threat. Her death profoundly impacted Sinclair, forging a stronger bond with Graham through their shared grief and mutual dependence, as they navigated the loss together in the immediate aftermath.[6]

Adventures with the Thirteenth Doctor

Ryan Sinclair joined the Thirteenth Doctor as a companion following a dramatic encounter in contemporary Sheffield, where an alien pod containing a Stenza hunter, Tzim-Sha, crash-landed and initiated a hunt targeting humans for sport. The newly regenerated Doctor, still adjusting to her form, crossed paths with Ryan—a 19-year-old warehouse worker studying mechanics—alongside his step-grandfather Graham O'Brien and local police officer Yasmin Khan. Together, they pursued Tzim-Sha, culminating in the hunter's defeat and the group's decision to travel with the Doctor in the TARDIS, forming the core "Team TARDIS" to explore time and space.[2] Throughout their journeys, Ryan participated in numerous high-stakes adventures that spanned historical and futuristic settings. The team confronted returning threats from the Stenza, including Tzim-Sha, who sought revenge during a New Year's incident involving a possessed Dalek exoskeleton, and reconciling with his estranged father, Aaron, during the events of "Resolution." They intervened in pivotal historical moments, such as the 17th-century witch hunts in Lancashire, where Ryan helped uncover an alien Morax invasion masquerading as supernatural events amid King James I's paranoia-driven trials. Other exploits included witnessing the human cost of the 1947 Partition of India, navigating the far-future desolation of a ravaged planet against the hope-devouring Remnants, and battling the interdimensional Kasaavin, whose incursion began with abductions in present-day Sheffield. These experiences often pitted the companions against classic foes like Daleks, with Ryan contributing to their containment in a covert British operation.[9][10][11][3] Ryan's time with the Doctor marked significant personal development, particularly in overcoming insecurities stemming from his dyspraxia, a coordination disorder that initially caused frustration in physical tasks like climbing a transmission mast during the Stenza crisis. He achieved breakthroughs in high-pressure scenarios, such as defusing tense situations with his emerging mechanical aptitude. Grappling with the grief of losing his grandmother Grace in their first adventure, Ryan processed his emotions through travels that fostered deeper familial ties with Graham, evolving from awkward step-relatives to supportive allies, while building a profound friendship with Yasmin rooted in shared vulnerabilities.[12] As the youngest member of the TARDIS crew, Ryan often offered relatable, Earth-bound insights that grounded the group's more impulsive decisions, drawing on his everyday perspective to question alien logics and advocate for empathy. His engineering knowledge proved vital in crises, from jury-rigging TARDIS components during malfunctions to devising traps against invaders like the Daleks, enhancing the team's resilience and collaborative dynamic.[3]

Departure from the TARDIS

Following the events of Series 12, Ryan Sinclair participated in the resolution of a Dalek incursion on Earth during the 2021 New Year's special "Revolution of the Daleks," where he and the TARDIS team confronted a plot by recon scout Daleks to create an army using human manufacturing facilities.[13] In the aftermath of defeating the Daleks, with the Doctor briefly imprisoned on Division's ship earlier in the story, Ryan chose to remain on Earth alongside Graham O'Brien, prioritizing support for his step-grandfather's ongoing grief over the loss of Grace O'Brien.[5] This decision marked the end of his travels with the [Thirteenth Doctor](/page/Thirteenth Doctor), as the team returned to Sheffield after an absence of ten months from Ryan's perspective due to the Doctor's captivity.[13] The emotional farewell unfolded inside the TARDIS, where Ryan articulated his resolve to build a stable life, stating, "I think I’m going to stay here. Me mates need me. And I know this sounds stupid, but I feel like my planet needs me. You got to fight for it, right?" This choice stemmed from his personal growth, transforming from a young man uncertain about his future—initially working in a warehouse while pursuing an NVQ in mechanics—into someone empowered to lead and contribute locally.[13] His experiences aboard the TARDIS had bolstered his confidence in managing dyspraxia, a coordination disorder that once hindered tasks like riding a bicycle, enabling him to embrace independence and reject the constant upheaval of time travel.[14] The scene culminated in a group embrace among the companions, with Ryan sharing a brief hug with the Doctor, underscoring the familial bonds formed during their adventures, before he and Graham exited the TARDIS for the final time.[15] Post-departure, Ryan returned to Sheffield to resume his engineering studies and apprenticeship, symbolizing his evolution from "the boy who can't," as he once self-deprecatingly referred to his dyspraxia-related challenges, to a self-assured young adult ready to apply his skills on Earth.[5] He and Graham began investigating anomalous events using the psychic paper provided by the Doctor, with Ryan taking a leadership role in pursuits like probing mysteries in Finland and Korea, while maintaining the close family dynamic with Graham that had helped the latter process his bereavement.[13] In-universe, Ryan's arc emphasized themes of family and personal healing, as his steadfast presence aided Graham's emotional recovery and reinforced the TARDIS team's focus on chosen kinship over cosmic perils.[15]

Portrayal

Casting process

The casting of Tosin Cole as Ryan Sinclair was announced on 22 October 2017, alongside Bradley Walsh as Graham O'Brien and Mandip Gill as Yasmin Khan, revealing the new companions for the Thirteenth Doctor in series 11.[16][17] Casting director Andy Pryor led the selection process, drawing from Cole's prior television work including roles in Holby City and Hollyoaks.[18][19] Series producer Nikki Wilson contributed to the overall production choices during pre-production.[20] Showrunner Chris Chibnall envisioned a diverse TARDIS team of working-class characters from Sheffield to ground the series in contemporary Northern English life, with Cole's chemistry reads alongside Jodie Whittaker, Walsh, and Gill confirming his suitability for portraying Ryan's youthful perspective.[21][22] Auditions occurred throughout 2017, with the cast contracted initially for series 11 and extended to multiple seasons; principal photography began in summer 2018, wrapping in early August ahead of the October premiere.[23][24]

Characterization and traits

Ryan Sinclair is characterized as a relatable young man in his late teens, often awkward in social situations yet infused with dry humor and unwavering loyalty to his companions. His personality draws from everyday adolescent insecurities, amplified by his developmental coordination disorder, dyspraxia, which affects his motor skills and contributes to moments of frustration and self-doubt. This portrayal emphasizes his resourcefulness and growing confidence, particularly in technical problem-solving, reflecting an innate aptitude for engineering as he pursues vocational training in mechanics.[14][25] The character's development evolved from initial depictions rooted in family grief and personal insecurity following the loss of his grandmother, positioning Ryan as emotionally vulnerable and strained in his relationship with step-grandfather Graham O'Brien. Over subsequent story arcs, writers shifted focus to his empowerment, showcasing increased independence, assertiveness in questioning authority, and strengthened familial bonds, culminating in a more self-assured demeanor by the end of his tenure. This progression highlights themes of resilience and personal growth, with Ryan transitioning from a hesitant newcomer to a capable team member who relies on his own initiative.[26][15] Tosin Cole approached the role by emphasizing authenticity in Ryan's portrayal, particularly in conveying the subtleties of dyspraxia through physicality and emotional nuance, such as hesitant movements and quiet introspection, to make the condition feel lived-in rather than stereotypical. He collaborated closely with co-star Bradley Walsh to build a genuine grandfather-grandson dynamic, drawing on off-screen rapport to infuse their interactions with warmth and tension, enhancing the familial authenticity of the companionship. Cole's performance choices, including subtle improvisations in physical scenes to capture motor challenges, stemmed from extensive research and consultations to ensure respectful representation.[25][15] In production, dyspraxia was incorporated into Ryan's character to promote disability representation, inspired by showrunner Chris Chibnall's nephew who lives with the condition, with the writing team consulting the Dyspraxia Foundation for accurate depiction of symptoms like coordination difficulties and associated anxiety. This element was revealed publicly at the series 11 world premiere on September 26, 2018, and later praised by the Foundation for raising awareness on mainstream television. Cole departed the role after series 12 and the 2021 New Year's special to pursue diverse career opportunities, a decision announced in March 2020 amid his commitments to other projects.[14][27][28][29]

Reception

Critical analysis

Critics have praised Ryan Sinclair for his relatable everyman quality, portraying him as a young man navigating everyday struggles such as dyspraxia, family grief, and an absentee father, which grounds the fantastical elements of Doctor Who in authentic emotional realism.[36] In episodes like "The Tsuranga Conundrum," his performance delivers a big emotional moment centered on daddy issues, allowing actor Tosin Cole to demonstrate considerable depth and class, further enhancing the character's appeal as an insecure youth evolving toward greater confidence.[37] Reviews of Series 11 also highlighted how Sinclair's background from a broken home contributed to stronger family themes and improved racial representation, aligning with the show's efforts to address its historical shortcomings in diversity.[38] However, Sinclair faced criticism for underutilization in later episodes, particularly as part of the four-companion ensemble in Series 11 and 12, which strained screentime and led to underdeveloped arcs reliant on quick resolutions rather than sustained exploration.[39] Compared to companions like Yasmin Khan and Graham O'Brien, who received more focused spotlights, Sinclair's role often felt sidelined amid the narrative overload, limiting opportunities for solo-driven stories.[39] Sinclair's overall arc culminates in his departure during the 2021 special "Revolution of the Daleks," depicted through a poignant, tender one-on-one scene with the Doctor that underscores his empathic growth and provides emotional closure.[40] Showrunner Chris Chibnall's writing has been commended for incorporating Northern representation through Sinclair's Sheffield roots and family dynamics, though the large ensemble has been critiqued for diluting individual impact across the series.[38] In comparative terms, Sinclair echoes modern companions like Donna Noble by prioritizing emotional depth and vulnerability over action-hero tropes, offering a grounded counterpoint to the Doctor's adventures through personal introspection and relational growth.[36]

Cultural impact and representation

Ryan Sinclair's portrayal marked a significant milestone in disability representation within Doctor Who, as he became the first major character in the series explicitly identified with dyspraxia, a developmental coordination disorder affecting motor skills and organization.[14] The depiction, informed by consultations with the Dyspraxia Foundation, highlighted everyday challenges such as difficulties with bike riding and ladder climbing, avoiding simplistic resolutions and emphasizing persistent realities.[14] The Dyspraxia Foundation endorsed the inclusion, praising it as a vital step in raising awareness of the condition, which affects an estimated 5-10% of the UK population but remains under-discussed compared to dyslexia or ADHD.[28] Following the 2018 premiere, the representation resonated with viewers, prompting personal stories of shared experiences, such as one dyspraxic individual's reflection on lifelong bike-riding frustrations mirroring Ryan's arc.[12] As a Black, working-class companion from Northern England, Ryan contributed to Series 11's push for inclusive casting under showrunner Chris Chibnall, who described it as the most diverse season in the program's history, featuring a writers' room with people of color for the first time.[41] His background as a warehouse worker studying for an NVQ underscored working-class resourcefulness and agency, portraying him as collaborative and ingenious alongside other everyday heroes.[42] Tosin Cole's performance as Ryan also advanced visibility for Black male characters in UK sci-fi, fitting into a lineage of figures like Mickey Smith while challenging tropes through familial and disability intersections.[38] Ryan's cultural legacy includes fan engagement with his "bike fail" scenes, which inspired memes and discussions on failure and resilience, often repurposed in educational contexts to explore themes of perseverance.[43] Post-departure in 2021, he has been referenced in companion rankings and retrospectives, appearing in 2025 lists of Doctor Who travelers as a notable figure from the [Thirteenth Doctor](/page/Thirteenth Doctor) era.[44] While lacking extensive standalone merchandise, his inclusion featured in broader BBC narratives on diversity, contributing to conversations about representation in family viewing.[41] Ryan's storyline has informed disability-in-media discourse, cited in analyses critiquing able-bodied portrayals while affirming its role in mainstreaming dyspraxia awareness.[45] The character's portrayal has been noted as an example of inclusive storytelling, emphasizing blended family dynamics and disability visibility in sci-fi.[5]
