"All right then," he says, and leans forward, lacing his fingers conspiratorially. "I love people, Ianto.

You keep me wanting to keep going, and you make it worth it."

He tilts his head, entirely unembarrassed, and smiles lopsidedly. "Even with the occasional misstep. Makes getting back on the right track all the better."
