Shout Out: Children of Time
- Clarke's Third Law is brought up twice, courtesy of the Doctor.
- Sherlock Holmes for Dummies is a real book!
- Kit Bennett is indeed a shout-out to Kitty Bennett from Pride and Prejudice.
- When Beth tells Holmes that her middle name is "Anne", she adds that it's spelled with an "e". Fair enough, though: Elizabeth Ann is used as a proper name.
- Thanks to Beth, Star Wars and The Lord of the Rings are briefly discussed.
- And she once uses Han Solo's most famous line: "I know".
- Holmes very movingly recites a love poem by Pablo Neruda.
