How Home Alone Prepares the Audience for Kevin’s Traps

The screenplay begins with people moving through doors, stairs, and rooms as the family prepares to leave. Luggage and interruptions help explain why Kevin is overlooked while also establishing the layout needed to follow the later action.

Kevin takes the empty house as proof that his wish worked. Being left behind gives him both a reason to feel rejected and the freedom to use every room without adult supervision.

Kevin chooses to defend the home where he has been left alone. Locking doors and turning on lights show him beginning to use familiar household routines for protection.

The montage shows how Kevin arranges ordinary objects into traps. It begins within the scene that sends him home from church, connecting his emotional reconciliation there with the decision to prepare his defense.

Source note: In this source draft, the preparation montage is embedded after the exterior church heading rather than separated into its own canonical scene.

The bell count, crowbar, door, and BB gun establish the timing of the first attack. The screenplay shows where the burglars will move, what will trigger each gag, and who will be hit.
