Kelvin (The Caretaker)

Kelvin was a student at Coal Hill School in Clara Oswald's English class in the 2010s. He was reading Pride and Prejudice aloud when the Twelfth Doctor, posing as the temporary caretaker, interrupted at the window to correct the date of publication written on the board. When the bell rang, Kelvin asked Clara about homework. Clara responded, "Who asks for homework? Amateur." (TV: The Caretaker)
