Jack chuckled. "It does tend to be a trait that runs in the military, doesn't it?" he asked, grinning, very fully aware that he might just be another one of the stubborn people in his life that Sulu was talking about. Especially with their rocky start, and their tendency towards arguing or just rubbing each other the wrong way. "I'm sure that Starfleet isn't that different from the other forms of military out there."

Jack directed Sulu which way to move, and on the count of three, they quickly maneuvered Ianto down the couch. It wasn't pretty, but they hadn't dropped him so that was a plus for them. Jack pulled Ianto's feet up onto the arm of the couch so that they were above his head level as he answered Sulu's question. "Smelling salts? Yeah, it works. I mean, it's not actually salt. It's a chemical compound that triggers an inhalation reflex. Because fainting is caused by a lack of blood to the brain, that usually wakes the person up. It sounds kinda primitive, I know, but it gets the job done." He looked up at Sulu from where he was kneeling beside the sofa, and shrugged. "I was a field medic for a while in World War II," he said, by way of explanation.
