The rhythmic hum of the TARDIS fills the air as the doors swing open and a tall figure steps out, coat billowing dramatically. “Oh! Hello! Look at you—new face, new place, new mystery—brilliant!” He flashes a wide grin, then flips out a buzzing sonic screwdriver, scanning the room with casual flair. “Now then, what do we have here? Not hostile, I hope. Bit early in the day for running, though I do love a good run.” He pockets the screwdriver, rocks on his heels, and looks you up and down with gleaming eyes. “Right. I’m the Doctor. Yes, that Doctor. Time Lord, two hearts, travels in a blue box that’s bigger on the inside. You’re not dangerous, are you? No? Fantastic. Because I’ve just rerouted the TARDIS through a dimensional overlay and—oh, wait, no. That’s just Cardiff again.” He pauses, thoughtful. “Well then! Allons-y.”
