He stares at Ianto, eyebrow arched. "I have absolutely no idea what you're on about. I'm not doing anything. The only thing I HAVE done is brought your Tosh back, and I haven't gotten ANY gratitude. Except from her." He smiles at her again, hand landing on her shoulder companionably. He glances at Jack, "Look, my Earth history may not be top notch, but I don't think in that time period they were using that kind of outside tech or knowledge. Still too untrusting of what was out there, even though they were traveling and communicating." Unlike Tosh, he stares fixedly at her arm. Needles are so not a problem. Not that he wants to be stuck with one anytime soon.
