- 奥古斯丁: "比试一下吗，先生？"
- 阿尔诺: "又一遍？"
- 奥古斯丁: "一场练习赛，仅此而已。作为刺客再怎么精心备战都不为过。"
- 阿尔诺: "难道我们的使命不是隐藏在阴影中？别让自己被发现之类的吗？"
- 奥古斯丁: "把这个称作后备选项吧。在安全的地方练习总比在街上与恶棍打架要好得多，不是吗？"
In 1793, Célestine, the servant girl of the Café Théâtre saw Augustin and Charlotte Gouze whispering together at midnight about the imminent closure of the convents of Paris, a dechristianization of the Revolutionary France which was greatly upsetting for Augustin. The young girl gossiped it to the intendant, who subtly told her to mind her own business by asking her what she was doing out of her room at midnight.
Later, bottles from the wine cellar of the café were stolen and the cook lady reported it to the intendant, telling him that she had seen Mr. Colignon, the gardener recommended by Augustin near the cellar. The intendant spoke of the matter with Célestine who did not believe in the guilt of Colignon, saying that as a gardener he didn't have the key of the cellar. Still suspicious, the intendant asked Célestine to follow Grisier and see what he was doing outside of the Café, because he found him mysterious and did not like to know so little about someone living in his house.
- Grisier is probably related or is loosely based on a famous fencing master of the same name born in 1791, Augustin-Edme-François Grisier, who was also known to be a good friend of the writer Alexandre Dumas, the son of Thomas-Alexandre Dumas.
