Luckily, Sulu was smart enough to divert his attention away from the idea of wandering through Ianto's mind with a quick recalling of a relatively basic equation - something that'd he'd learned to do in case of psychological warfare. Kind of like recalling his name and rank repeatedly, but a little more involved. "Not that there's much not to know," Sulu shrugged.

He bit his lip at the stray name he heard, looking a little awkward. "Yeah, it doesn't seem like something that's easy to control. You want me to take this off?" Though it was really cool, he wasn't about to let Ianto accidentally let anything else slip that he obviously didn't want heard.
