Blood Ties

Jiang Shi (meaning "stiff corpse" in Chinese) are not exactly vampires but reanimated corpses that feed on the life essence of other creatures. They are created when a person's soul does not leave the body after death and they are depicted as having greenish-white furry skin, perhaps to indicate the corpses' fungus.

Goof: When you see Henry go after Vicki, you can see that he no longer has the burn marks on his left shoulder. So how can he heal if he hasn't had any blood.

The fictional device known as iluminación del sol is Spanish literally meaning "the illumination of the sun." It was created by a Daoist monk to steal immortality from vampires. Religiously, the highest ideal of a Daoist is to acquire immortality.

Besides its fairy tale connotation, "happy endings" can also refer to a masseuse who finishes a client's session with oral sex or manual release.

Goof: Detective Lam mentions that Javier Mendoza was a "Grand Inquisitor during the Spanish Inquisition". It sounds like there is a specific time or historical period for the Spanish Inquisition, while in fact this institution was founded in 1478 and abolished in 1834. Although there is no famous Javier Mendoza associated with it, three-and-a-half centuries of work give room for a lot of possibilities.
The Spanish Inquisition was most active in Spain during the time of Henry Fitzroy's birth, mainly as the means to cope first with a very religiously diverse population, much of it inherited after the last Spanish Islamic kingdoms were conquered, and later with the Reformation. By the date of 1742 mentioned, it was barely tolerated and acted only as the Censorship office for arts and literature. Witch-hunting was not one of its major activities, probably about a 10% only, since the Inquisition preferred to focus on heresy (which included all forms of Protestantism) and false conversions instead. Their biggest witch trial (11 condemned out of 7.000 questioned) was in 1610, and the inquisitors themselves dismissed most of both accusations and confessions as superstitious nonsense.
