(SPOILER ALERT) When the real Mandarin's assistant gives the guy a brief case and the guy ends up blowing up near the Chinese Theater and those that where near the explosion vaporized, while others that were surrounding the area got there shadows engraved into the walls. Also when Tony is vising that town in Tennessee and he realizes that there are shadows on the walls as well.

Literally, POOR X-men
