Bridget (Sarah Michelle Gellar) and Malcolm (Mike Colter) find a note in Charlie’s apartment. It says “Siobhan, pivoine 419”. Pivoine is French for peony. 419 is either a Paris telephone exchange or the area code for Toledo, Ohio.
In Paris there is both a Chinese restaurant and a Vietnamese restaurant named Pivoine. The term is also attached to a classical Chinese Opera, THE PEONY PAVILION, which centers on the love story of Liu Meng-mei (Willow Dreaming Plum), a young student, and Tu Li-niang, the daughter of a high official in southern Kiangsi. It is a long play, with 55 scenes.
Pivoine is also a musical duo, Lulu-Pivu & Uku-Kéké, and a solo chanteuse, Ludiane Pivoine (see video below).
