Character mistake: The newspaper that reveals the combination of products that activates the Joker's poison has at least two grammar mistakes on the front page. The word "deodorant's" should not have had an apostrophe, and the word odoreaters was spelled "odoureaters," which has the British spelling of the word odor (Gotham City is obviously in the United States, not the UK).

Question: How did Grissom figure out Jack was sleeping with Alicia?
Answer: Eckhardt ratted Jack out after getting assaulted by him and muttering under his breath: "Where've you been spending your nights?" He watched Jack long enough to get dirt on him and told Grissom that Jack was stealing his woman. Grissom confirmed it by inviting her up to his apartment when Jack happened to be there and watching to see if they recognized each other. Then he immediately set Jack up to take the fall for Axis Chemicals and gave Eckhardt the tip to get there first and assassinate him.
Answer: He was suspicious, but when she first entered the penthouse and Grissom said to leave their business meeting, he noticed the sexy facial exchange Alicia and Jack gave each other.
