"Doctor?" Donna asked one day.
She would swear she learned more from him in one year than from all her teachers in school for ten.
"Yup?" he beamed, jumping out from under the console.
"What words start with 'X'?" Donna asked out of the blue.
"Um. . . English words?" the Doctor asked, furrowing his eyebrows.
"Yes, Spaceman, English words!" Donna cried, amused.
"Well. . ." the Doctor thought for a moment. "X-ray, xanax, xenon—"
"What do they mean?" Donna interrupted him.
"What, x-ray?" the Doctor wondered. "It's—"
"No, no, no! The other ones! Xorax. . . or xenone. . . or something like that," Donna said.
"Oh! Xanax!" the Doctor realized. "It's an anti-anxiety agent. It's a benzodiazepine, 'xanax' is only its trade name."
"Oh," Donna nodded. "And what about the second one?"
"Xenon," the Doctor reached into one of his numerous bigger-on-the-inside pockets and took out his glasses. "Is an odorless, colorless, very unreactive gas. It's an element. It's found in tiny amounts in the Earth's atmosphere, and is commercially extracted from liquefied air. They—you—humans use it in bacterial, stroboscopic, and bactericidal lamps."
"Uh-huh," Donna nodded, her eyes wide. "I think I'm just going to look it up."
"But that is from the dictionary!" the Doctor cried. "Look!"
He took out an iPhone (of all the things) and clicked on the dictionary app. There, like he told Donna, with just a couple different words, was the definition for 'xenon'.
