If you have read all of the Harry Potter books, you know that several of the small details that we just dismissed at the time actually come to have a lot of meaning. However, it's probably not until you've read all of the books (maybe even several times, hell you might not even notice until it's pointed out to you). I'll be talking about my five favorite small details.
Snape's First Conversation With Harry Was Incredibly Significant
"What would I get if I added powdered root of asphodel to an infusion of wormwood?" Snape asks Harry this very question when they first meet in Harry Potter and the Philosopher's Stone. At first, it seems like Snape is just picking on Harry, but if you really pay attention to the question, you know it's so much more than that. Asphodel is a type of lily. This particular type of lily means "My regrets follow you to the grave." Wormwood means 'absence' and it meant to symbolize sorrow.
Why Professor Trelawney's (mostly) Bogus Assumptions Never Got Her Fired
When we are first introduced to Professor Trelawney in Harry Potter and the Prisoner of Azkaban, we quickly learn that her predictions are bogus -- until the end of the book anyways. Trelawney predicts that servant (Petter Pettigrew) and master (Lord Voldemort) will be reunited once more. Trelawney also goes on to predict the death of Albus Dumbledore (who was the first to rise at a table of thirteen [Sirius Black and Remus Lupin go on to do the same thing and they later died as well]). She could also sense Voldemort's soul residing in Harry, which is why she always thought Harry was born in mid-winter (Voldemort's birthday is December 31).
Why the Weasley's Neighbors Were Worth Mentioning
"Must be nearly time," said Mr. Weasley quickly, pulling out his watch again. "Do you know whether we're waiting for anyone else, Amos?" "No, the Lovegoods have been there for a week already and the Fawcetts couldn't get tickets," said Mr. Diggory. "There aren't anymore of us in this area, are there?" Harry Potter and the Goblet of Fire is where we first hear any mention of the Lovegoods, who eventually become very important.
