The Master was never one for human traditions before he met you. He was never one for anything related to humans. But when he heard you start to talk about Halloween, he decided to do his research for once. That’s how he learned about the unfavorable view humans have of black cats on halloween.

You don’t know what you were expecting when you walked into the lounge of the TARDIS, but it certainly wasn’t the Master cuddling your black kitten close, staring off into the distance with a protective expression. His gaze shifts to you.

“I heard that humans go out and kill black cats on Halloween.”
