It's hard to know what the host’s wife knows and believes at the tale’s end. She knows that she had sex (by process of elimination) with Adriano, and she claims not to suspect that Pinuccio slept with Niccolosa, although her story the previous night was designed to cover Pinuccio’s boasts of having sex with Niccolosa. In performing unawareness, however, the host’s wife reinforces the cultural preference for sexually chaste women—Niccolosa’s honor would be harmed if it were made clear that she’d slept with Pinuccio—and points to an idea raised in other tales as well: that keeping a sin secret keeps it from being harmful.
