i loved reading that chapter. It had one of the powerful moments in the series for me, when i think 'this book is so great'.
Spoiler: It was when Haruhi remarked during the day that she wished the pigeons in the scene were white (a reference to a director, i think it was wantanabe soichiro? Correct me if im wrong)and Koizumi decides to take Kyon on one of those nighttime car rides (like Akio Ohtori) where he talks on and on about something profound(Koizumi is the only guy i ever got annoyed at for talking and thinking too much. I generally encourage thinking among teenagers), and he takes Kyon back to the set and finds the pigeon are now white. It had a real impact when i read that.
