What is the significance of the glass room in John Wick: Chapter 2?

The glass room in John Wick: Chapter 2 plays a significant role in the film's climax. The room is located on the top floor of the Continental Hotel in Rome, where John Wick goes to seek out Santino D'Antonio, a member of the High Table, who has placed a contract on Wick's life.

The glass room is designed to be a neutral space where no business can be conducted and no violence can occur. However, when Wick and D'Antonio meet in the room, Wick learns that D'Antonio has no intention of honoring the rules of the Continental, and he attacks Wick with his bodyguards.

The glass room is significant because it is the place where Wick and D'Antonio engage in their final showdown. The glass walls and ceiling of the room provide an impressive visual backdrop to the intense fight scene, which involves both hand-to-hand combat and gunplay.

The glass room is also symbolic of the fragile balance of power that exists in the world of John Wick. Despite the strict rules and codes of conduct that govern the assassins' world, violence and betrayal are always lurking just beneath the surface.
