Captain Jack Harkness swung from the jumpseat towards the broody Time Lord who was leaning over the console of his TARDIS, blue eyes boring into the monitor. "Hey Doc," he called.
"What?" The slightly superior alien who called himself the Doctor replied gruffly. It was a rough day for all of them. Somehow, the Doctor had gotten himself stuck in a slave trade, which resulted in Rose being kidnapped and almost sold to a slimy slug-like creature. He genuinely didn't like the way it leered at Rose while she was in chains, forced to follow a line into a platform.
In short, after a meticulously said string of words at the slug, the trader and basically every creature on that planet about slavery (plus some extra bomb threats later), the Doctor and Jack managed to rescue their champion damsel in distress.
When they get back into the TARDIS, she had quickly disappeared into the corridors, leaving Jack the only subject of the Doctor's fury. Jack being Jack was less than cooperative at being a silent subject.
"Rose looked absolutely delectable in that Princess Leia slave getup, don't you think?" Jack said, prolonging the word absolutely. "If it was on any other context, I'd say she was enjoying the looks you've been giving her." He was pushing the buttons, here. "Well… Good luck, Doc," he said with a saucy wink before dashing into the corridors as well, cackling like an idiot.
He didn't need luck. He had the skills. After all, the Doctor was so impressive. So impressive that in bouts of them running back into the TARDIS he'd managed to tell Rose that he wanted the outfit to stay. It was just a matter of getting rid of Jack, and even that had solved itself. If this were pasta, it would be al dente.
So with a cocky, winning smirk on his face, the Doctor strolled down the corridors as well. A Princess was waiting at it's end.
