Ryan Sinclair

Ryan Sinclair worked as a warehouse worker, earning money while studying for his NVQ so that he could become a mechanic.

Early life
Ryan was born in 1999. As a child, he attended Redlands Primary alongside Yasmin Khan, (TV: The Woman Who Fell to Earth) and was placed in a class named for Rosa Parks. (TV: Rosa)

In 2012, Ryan's mother passed away and he was raised by his paternal grandmother Grace. (TV: The Woman Who Fell to Earth)

Meeting the Doctor
In September 2018, whilst trying to learn to cycle with Grace, and her husband, Graham O'Brien, Ryan fell off and threw the bicycle away into the nearby woods out of anger. After his grandmother and Graham left him to calm down, Ryan went to retrieve it.

Whilst retrieving it from a tree, he discovered a glowing symbol and, upon touching it, summoned a strange blue pod. He touched the pod only to find it freezing, burning his hand. Calling the police to investigate, Ryan was reunited with Yasmin Khan, a classmate from school who now worked as a police officer, when she arrived to investigate the scene. Ryan confessed it wasn't a prank, making Yasmin confirm such by touching the pod. Walking away, Ryan received a call from his grandmother asking for help on the nearby train.

The pair raced to it, where they met the Thirteenth Doctor and were subsequently electrocuted by a coil creature. Ryan helped the Doctor track down the pod's occupant, Tim Shaw and prevented him from claiming Karl Wright as a trophy. However, Grace died via electrocution when disabling the gathering coil. Devastated, her death motivated Ryan to battle his dyspraxia in her honour. He later helped the Doctor make a teleport so she could reach her TARDIS only to be teleported with her.

Believing the pair to be bonuses in the Rally of the Twelve Galaxies, Angstrom scooped Ryan and Graham out of deep space and transported them aboard her ship.

On Desolation, he found Yasmin and the Doctor, who had been similarly saved by Epzo, Angstrom's rival in what would become the final stage of the rally. The rivals, with the Doctor and her friends in tow, were tasked by Ilin, master of the rally, to race across the planet; the first to reach the finish line at the Ghost Monument would win 3.2 million krin and salvation from planet's hostile surface. The Doctor discovered that the Ghost Monument was, in fact, her TARDIS, phasing in and out of reality. After the Doctor stabilised the TARDIS, Ryan entered it for the first time and the Doctor started to take them home. (TV: The Ghost Monument)

Personality
Ryan was skilled with social media. He had his own YouTube account called RyanS and chose to search Twitter when asked by the Doctor to look for any unusual recent events. (TV: The Woman Who Fell to Earth)

Ryan's studies as part of his NVQ meant that had some understanding of mechanical engineering. He was able to fix a solar-powered boat, enabling the group to navigate the waters of Desolation. His qualification also meant he knew basic facts about acetylene. (TV: The Ghost Monument)

Ryan had dyspraxia, a coordination disorder, which often frustrated him. He struggled to ride a bike and lost his footing while climbing a crane. He was also scared of heights. (TV: The Woman Who Fell to Earth)
