This was their job, to protect the world from the dangers that were out there. Their own lives, unfortunately, would always have to come second. He knew that and he understood that, but sometimes he just wanted to say sod the universe. Jack had done enough and sacrificed enough and he more than deserved a break. They both deserved a break. But that wasn't how the world worked.
Ianto gave Jack a look that was equal parts innocence and amusement and raised an eyebrow as if to say 'Who? Me?' But he did know Jack's weaknesses, and he wasn't afraid to exploit them for his own benefit. It was like the Welsh. Jack claimed to understand it, but he had a tendency to make a mess of it when he tried to speak it. And they wouldn't even get into how bad he was at reading it. It was somewhat disconcerting, considering he'd lived in Cardiff for over a hundred years. But that was neither here nor there. "I've hardly heard you complaining," he pointed out.
"Well," Ianto said, teasing, "the fact is that the coffee you drink would most likely kill mere mortals. So perhaps it's best that nobody else is capable of making it." That and he liked that it was something he could do for Jack. He raised an eyebrow at Jack's description of himself and shook his head. "Punchy...of course." Somehow, he didn't exactly think it was the best word. He smiled with amusement, prepared to assure Jack that keeping him caffeinated for the good of the general public was indeed his intention, but then Jack had pulled him close enough to feel his body pressing against his own and suddenly coffee was the last thing on his mind. "You are," he agreed breathlessly, eyes wide and dark, and why the hell were they still talking. "I know you will, Jack. Cara 'ch hefyd. Now, if you don't mind sir, do shut up." He had much better ways to occupy Jack's mouth.
