The quote humorously suggests the need for a discreet hand signal to communicate a sensitive situation regarding the prince's romantic involvement. It points to the idea that such signals could help convey important messages without drawing attention. The speaker expresses amusement that the Italians, who are known for their expressive gestures, have not yet devised such a signal.

This remark reflects the blend of political intrigue and personal relationships common in Hilary Mantel's "Wolf Hall." The playful tone underscores the complexities of court life, where alliances and behaviors must be navigated carefully, making humor an effective coping mechanism in serious situations.
