The Doctor stared with interest at the console. "Type 57 model. Nice. Does the reflux condenser still stick on cold days?" The man lounged back on a couch. "Yeah. And it's a bitch." Rose leant against the rail. "So, you're a Time Lord." The man grinned."Yep." Rose frowned. "But you've got an Australian accent."
"I'm from south of the equator."
"Right. You have a bathroom?
"Down that hall, just after the armoury." The Doctor turned to face him. "You have an armoury? Why would you need an armoury?" The man glanced at him. "Well, I've learnt that if you rock up in Ancient Greece carrying a trivalent oscillating pulsar rifle, people start giving you weird looks. So I've got an armoury, filled with everything from spears to sniper rifles." The Doctor frowned. "But why do you need to carry a weapon around?" The man shrugged. "Sometimes, I find the only way to get things done is with a little violence. Sucks, but it's true."
"Only idiots and evil men carry weapons. Which one are you?" The man leant forward. "Oh, come on, Doctor. You've seen wars. You fought in the Last Great Time War. You know I'm right, even if you can't admit it." The Doctor stuck his chin out, and pouted "Well, I seem to be doing fine with just my wits and a sonic screwdriver." The man laughed. "A sonic screwdriver? Why the hell would you have a sonic screwdriver?"
"What, you think you've got better?" the Doctor said, feeling slightly insulted. The man reached into his pocket, and pulled out a device that vaguely resembled a flashlight. "Sonic multi-tool. Works on metal, wood, plastic, you name it. Also has tweezers." The man slipped it back in his pocket. "Never leave home without it." The Doctor frowned again. "Do you realise how much frowning you do?" The man asked. "What's wrong this time?"
"You remind me of someone."
"In what way?"
"You're overconfident, you use guns and you have a odd accent."
"Cheers."
"Have you ever met a Captain Jack Harkness, by any chance?"
"Who, the Face of Boe?"
"No, Captain Jack Harkness."
"Like I said, the Face of- oh, never mind. Yeah, I've met him. We play poker every now and then. Bastard won't stop coming onto me."
