That scene from Pride & Prejudice (2005) US version but with A and the detective deep in romance: "How are you this evening, Detective?" "Very well... Although I wish you would not call me "Detective". "What endearments am I allowed?" "Well let me think... "My nickname" for every day, "My name" for Sundays... You may only call me "Lux mea (My light)" when you are completely, and perfectly, and incandescently happy" "How are you this evening, Lux mea?" A gets closer, showering the detective's face with light kisses while whispering "... Lux mea" over and over.
