His parents simply didn't understand. His devotion wasn't a simple boyhood crush. What Jethro felt was the right thing. What happened on the train to Midnight changed his life for the better.
Jethro had seen how the Doctor faced danger everyday of his life. The Doctor needed someone to accompany him along his journeys to Columbus and other tourist planets fret with danger.
Alright, that seemed a bit silly. But… he wanted the Doctor to devour him. To show him everything in the universe he wasn't supposed to know. Jethro was okay of prospect being a slave to a holy idol. Jethro's right hand was already the Doctor's slave so why not the rest of his mind and body?
Jethro sighed as he packed his bag for Columbus. He knew if he stayed long enough, he'd find his Doctor.
