“Doctor! You’re on fire!” Clara shouted, running towards him.
“Your coat’s burning!”
The Doctor peered over his shoulder at the back of his coat. “So it is.”
Pulling off her jacket, Clara used it to beat ineffectually at the flames, but that only made them leap higher. “You’re supposed to drop and roll,” she urged him. “Suffocate the flames!”
“Oh, there’s no need for all that. Now where did I put it?” Thrusting one hand into his pocket, he rummaged around. “Try this.”
“You keep a fire extinguisher in your pocket?”
“Never know when it might come in handy.”
