Ianto was the one holding the box with the recipe on it, which, in Sulu's eyes, was enough to make him the one in charge (as if being in his kitchen, cooking in his century wasn't enough). So, when Ianto suggested they sit, he easily moved to one of the chairs closest to Ianto, sinking into it and looking at the other man.

"Did you ever expect me to seriously take you up on the suggestion of cooking at home?" Sulu asked, grinning a little.
