Danny Pink
Danny Pink was a teacher at Coal Hill School, where he taught mathematics. He had previously been a soldier, and established the Coal Hill Cadet Squad at the school.
A pupil once asked if he had killed anyone, to which Danny implied that he may have killed enemy soldiers. The student then pressed the matter by asking if he had ever killed anyone who was not a soldier. Although he refused to answer, Danny became visibly distressed.
He was introduced to Clara Oswald by Mr Armitage. She invited him to join her at a colleague's event after work that day, which he initially declined - and act he immediately regretted. While reviewing this awkward moment to himself, Clara overheard him. Although this further embarrassed him, he gratefully accepted her offer to grab a drink together. (TV: Into the Dalek)
