Character biography Early life Ryan Sinclair was born in 1999 or late 1998. As a child, he attended Redlands Primary alongside Yasmin Khan and was placed in a class named after Rosa Parks. In 2012, when he was thirteen, his mother died from a heart attack, with Ryan being the one to find her body. After his mother's death, Ryan's relationship with his father soured to the point of parental abandonment. He began to feel that he wasn't deserving of his father's love. Ryan was then raised by his paternal grandmother, Grace. Young adult life Ryan suffered the effects of racism and noted that he was stopped more often by the police than his white peers.
