Jeremey plays pool with Stix. Stix starts off by hitting the yellow stripe ball (number 9). BUT the ball that he sinks is suddenly the green stripe ball.
Jeremey plays pool with Stix. Stix starts off by hitting the yellow stripe ball (number 9). On this shot he sinks the green ball. He next sinks the orange stripe ball. BUT he hits and sinks the solid orange ball (number 5) with his next move. In 8 ball this means he scratched and it became Jeremey's turn, Instead, Stix continues to play in violation of the rules of 8 ball.
In the fourth act, Jeremy Pike plays a high stakes game of 8 ball with Gideon Stix. However, the game of 8 ball was a 20th Century invention.
Opium smuggling, the basis for the plot, is not plausible, as the events were probably before there were any legal restrictions at all on opium sale or use. In 1875 (probably after the events in this episode occurred), San Francisco passed an ordinance making opium parlors illegal but did not otherwise restrict its sale or use (and was motivated more by anti-Chinese than anti-drug sentiments). In 1897, the state of California passed a law requiring warning labels on narcotics and that purchases be registered. In 1907, opium was further restricted to prescription sales and was finally outlawed altogether (along with opium pipes) in 1909.
Pike identifies the coded book as Shafton's Reflections on Good and Evil, Vol. 1, first edition, published in England, 1575. But the close-up of the page clearly reveals the book to be of much later date, with references to "Bat Masterson, one of Marshal Earp's deputies" and to "hit song stylist Arnie Haines."
Karate first came to America through immigrants from Japan and Okinawa. The first recorded exhibition was in 1932 in Hawaii. Servicemen coming back after World War 2 brought knowledge of the art and helped spread the art.
After Cranston breaks his glasses, which prevent him from reading the book, Jim gets him an eye piece. But when Cranston reads the book while using the eye piece, he only does two passages over the top third of each page and does NOT look at the middle or bottom thirds of those pages. Therefore, Cranston could NOT use his photographic memory to record two thirds of the book he needed to remember.
At the end of the program, Cranston invites Jim and Jeremey out with himself and three women that he knows (a triple date). Jim and Jeremey decline the invitation because they think their only assets could only be their intelligence (and therefore they must be unattractive). Cranston leaves and Jim and Jeremey look out the window and see Cranston join three attractive women in a carriage that only has room for FOUR. So if Cranston's invitation had been sincere the women would have had to have arrived in a SIX seat carriage (which would been able to handle Jim, Jeremey, Cranston, and the three women). Perhaps Cranston had envisioned Jim and Jeremey trotting along side of this carriage on this outing.
