Max has picked up the brick from the floor.
Heidi: Max! Are you OK?
Max: Yeah, and even if I would have been hit… it's only a simulation.
Heidi: I am almost forgetting, it is astounding how realistic it is. But, who would launch a brick at a window of a museum?

Alfred: It's all OK, it is just a brick squad.
Zhang: A what?!
Alfred: Don't you know? People drive around in trucks with bricks, and throw them at random buildings. It is supposed to be good for the eco… nomy. It creates work for many, even doctors when the brick hits someone.

An outside view of the museum, with a pick-up truck marked ‘BS’ driving away in the foreground, a person in its cargo bed next to a pile of bricks is ready to throw another brick.
Zhang (voice from within museum): This is officially sanctioned? I want to meet those in charge… or maybe not.
