"Ianto!"

Ianto swallowed a sigh and seriously considered keeping a stash of half-caff especially for the Captain. He had far too much energy and really didn't need the caffeine making him go manic with it.

"Yes, sir?" Ianto responded, fixing his pleasant smile.

"What are you doing after work?"

Usually that would be going home, eating, falling asleep in front of the television, and hoping to hell he didn't get a call to come dispose of a weevil or make a death look 'accidental' and retcon a block of flats. Since Jack and Ianto had started… whatever it was they had started, that routine was occasionally interrupted. Jack didn't usually ask outright though. It was usually more of a heavy suggestion, as in, "How about you stay late tonight?" The combination of mischievous grin, gleaming eyes, and that tone of voice was a lethal one that Ianto was sure Jack had been perfecting since whatever age people hit puberty on Boeshane.

"Quite busy, sir. But then, you don't know about my secret after-hours identity as a night watchman for the local library. I keep the world safe from the Book Crook and his band of -"

"Think we could sneak in a jog before you're on duty?" Jack interrupted.

Well, that was… unexpected, Ianto thought. Or was 'jog' some new euphemism of his? "I… suppose I could dust off my trainers."

"Don't be so modest. I know exactly how fit you are," Jack grinned smugly. "Anyway," he continued, "I just thought it might be more fun to work out together."

"I was fairly sure we already did that. On a regular basis," Ianto said, barely holding back his own smirk.

"Yeah, but I meant legitimately," Jack said, his grin softening just a bit.

"Alright," Ianto agreed. Though he generally preferred to tune out the rest of the world when he took exercise, he could see enjoying Jack's company on a more social level. Jack was certainly never stuck for conversation anyway. "I'll just get my bag from the car."

Half an hour later, Ianto closed up the tourist office and met Jack out on the quay. He tried not to stare but Jack looked really good in running shorts. In fact, Jack looked almost obscene compared to Ianto's more modest trackies and t-shirt. And Ianto had no doubt Jack would end up whipping his shirt off before they'd done even a half-mile, just because he could.

"Ready when you are," Jack said in a way that sounded way more inviting than an evening run should have done.

Ianto nodded and they set off at a warm-up pace up around the Plass.

"You know, Yan, I've been thinking," Jack said as the passed the car park.

Ianto held back a sigh. Now it made sense – time to themselves, non-romantic physical distraction… perfect for a personal chat. "What was it like?" Ianto teased, hoping to keep things light.

Jack just smirked and nudged him. "I mean about the SUV."

"No I don't think we should add under-car lights," Ianto said dryly.

"Those are a safety feature," Jack protested. "That's not it either though. It needs a name. I mean, ships have names, and all the really cool cars have names…."

"Jack. I had that figured out since day one. It's the Weevil-mobile. Should've thought that was obvious."

Jack sighed and shook his head. "This is why you're my archivist," he said, picking up the pace and pulling off his shirt as he went ahead.

Ianto just grinned and increased his pace to match. Only Jack Harkness would consider going for a run as an opportunity to flirt with someone he had absolutely no need to "try" for. Ianto had the feeling they were going to be working out together a lot more often.
