    First major diversion from the books: the series starts with Alec, Izzy and Jace chasing a demon to Pandemonium in 2017,but in the book it was 2007. Bam,bishes:)

    • Space Parrot

      Oh P.S.: I realized that the difference in time isn't really a diversion, because the book itself and the series too are set in modern day (as in right now), its just that the series was made almost 10 years after the book was released. For the real diversion: well Clary and Jace don't bump into each other like that, she oversees Alec, Izzy and Jace killing a demon in a storage room in Pandemonium. Its not that major though. Well there's also Dorothea, who isn't like a sister to Clary in the books, more like a weird old neighbour who doesn't really go out of her room a lot.
