Sulu sighed, a little bit relieved. It was by no means too much for him, but he'd rather everyone in the car be happy; he hadn't been sure if Jack was going to listen to him or not, but apparently it had been worth the attempt. "Must be. I'm used to things without wheels - or other vehicles right by you that you can crash in to. But, for all I know, it could just be my poor feminine biology." He didn't sound sick or upset, that was for sure.

Ianto's smile wasn't unusual to see but, for some reason, this one made Sulu feel better than he'd thought it would. Maybe it was because Ianto was grateful instead of upset with him for taking the reins like that, or maybe it was just because they were on the same side for the first time today, hand-in-hand in the back seat of the car. He wasn't sure; he didn't care, either. He just knew that Ianto's grateful smile made his stomach twist pleasantly, in a way he hoped to feel more.
