Rory snorted. "No. No, definitely not, not engaged to him. No. I like my sanity intact, thanks." Psycho Otter Guy? Well, he'd heard the Doctor called worse things. Though he had to wonder the cause of the nickname. "I see you've met him though, he tends to make an impression. And yes, time traveler. The TARDIS is a time machine. Well, normally. Right now its just a blue box with an inordinate amount of rooms at odds with its physical size."

He paused, considering lying to him. "Ah, yeah. It's possible. But that's what your file says. Did you take vitamins as a child? Improper nutrition in childhood can result in lower than average height."

Or he could just be short, naturally. Which was what Rory was leaning towards.
