At Sulu's nodding toward the souvenir shop, he shrugged slightly, nodding. "Sure, why not. Seems like there should be at least something in there." Whether there would be anything that caught Ianto's eye was another story, but. Why not give it a try, anyway. Sure, the place looked a little kitschy, but. Who knew, maybe they'd find exactly what he was looking for, even without knowing what he was looking for in the first place.
