The boss's name is taken from Tarot cards, more specifically the Major Arcana section (Chariot, Hangedman, Hermit, and Magician).
The events take place on 18 December and 20 December 1998. After Sophie's call on 18 December, Thomas and G came to Dr. Roy Curien's house to save Sophie two days later.
Sophie, despite seemingly killed by Chariot, remains alive in the series. This is proven by her giving birth to Lisa Rogan about a year after the incident. Lisa later will appear as the main protagonist in The House of the Dead III, set in year 2019.
