What I’d do:
At the City of Bones premiere:
- Wear a black jacket (caz you don’t have to be a shadowhunter to look this good) zipped up
- Enjoy the awesomeness it’s sure to be
- When movie is over: watch the non-readers freak out about Clace being siblings
- Casually rise and turn to face the theatre
- Unzip jacket to reveal special shirt
- Watch non-readers become confused and frustrated
- Enjoy maniacal evil genius inner laugh
- Calmly walk out like a spoiler boss
