Not people, Ianto. Rose. Those two shared secrets like girlfriends half the time, especially of the romantic variety. Surely you didn't think the tales of Jack's adventures stopped after he met you! "Your driving skills," Rose said, trying to look as serious as she could manage without bursting into giggles again. "Oh, and you place a mean pizza order." Well...who didn't? It had to be a good guess!
"He's a good man," Rose told him, wiggling her toes a bit to get some feeling back in them. "And you must know, if you hurt him, I'll have to off you. I don't look forward to it, please don't make me. I'm not much for blood so I'd have to smother you in your sleep." She shot him an angelically innocent look and laughed a little, but she did mean it. Sort of. She wouldn't kill him. But if anyone hurt Jack after everything he'd already been through? She'd rip them apart, if only verbally.
