Rowan Fairley
From Tardis Wiki, the free Doctor Who reference
Rowan Fairley was a student at a boarding school in Scotland. He was fat-shamed by Lawrence McAllister. Missy kept him in school over the Christmas holidays. He helped Oliver Davis investigate Missy's plans. He was crucial to Missy's plans as he was born on the winter solstice so could be used as a sacrifice to wake the god of winter.
