John moved around a lot because of his father's work in the army, and he never made any long-lasting relationships because of it. When both his parents died, he thought he would finally settle down and rebuild his life but things are never that easy. Like every family, his family had secrets too. For as long as John could remember, he was prone to headaches, but the longer he stays at St. Bart's, the worse his headaches become and the more he remembers of a past he feels should have stayed forgotten. It doesn't help that his teenage libido is craving for Sherlock Holmes, his weird classmate with a penchant for being an ass, either.
