In the McAllister household, Kevin places the soldering iron onto the doorknob
Kevin: When those robbers try to break in they'll be in for a nasty surprise.
In his room, Kevin unfolds his map of traps
Kevin: Nails on basement stairs... check. Iron attached to string... check.
Downstairs, Kevin looks over the ornaments and toys he's cunningly placed on the floor
Kevin: Trucks, ornaments... check. Paint cans...
Upstairs, Kevin checks the rope connected to the paint cans
Kevin: Check.
In his room, Kevin is in bed and prepares to go to sleep
Kevin: Safe and sound.
Kevin goes straight to sleep. Outside the room, the iron connected to the door knob starts burning and soon causes a fire to start. The smoke spreads into Kevin's room, which causes him to start coughing. He wakes, realizes what's happening and puts his hands to his cheeks in the cla**ic Home Alone pose
Kevin: The fire!
Coughing violently, Kevin heads to the stairs... but has forgotten about the trip wire at the top. He pulls it, causing the paint can to smack him in the head. Kevin is sent violently bouncing down the stairs, breaking a bone with each bounce. Flying into the wall at the bottom, Kevin attempts to recover but instead falls face first into the objects he placed on the floor, causing even more pain. Kevin screams, does the pose, and goes for the door knob with the iron on causing him to burn his hands. Still screaming, Kevin puts his hands to his cheeks only to find that because of the burn his hands are now melded to them. Now in agony, Kevin runs to the basement and starts walking down the stairs only for the nail he placed there to go through his foot. Kevin now starts crying, and he falls painfully down the stairs. He tries to turn on the light... to find this is the light he connected to the iron above. The iron falls on Kevin's head... and he screams no more.
Outside, as the house burns in the background, Kate, Peter, Harry and Marv all watch as Kevin's body is taken away by the paramedics.
Harry: We were just driving by when we saw the flames. Is that kid gonna be ok?
The sheet covering Kevin's body is pulled back to reveal his burned, stabbed face still with his hands melded to it. Now it's Kate's turn to scream and she, you guessed it, puts her hands to her face.
