After the incident, Robbie goes completely off the deep end and decides to get away from everything by leaping off the World Trade Center and using a spell to fly to his fantasy dimension. (Reminder: This will not work.) The scene in which his friends confront him on the roof is without a doubt the greatest moment in Tom Hanks' entire acting career:
"Remember kids: D&D is the devil, and profound psychiatric issues can be cured with the power of hugs."
Unfortunately, Robbie is never able to break out of his delusion. Such is the strength of tabletop gaming's evil. Thus, he's doomed to wander mindlessly around his parents' estate for the rest of his life, mentally trapped in his made-up fantasy world. And the film would have us believe that this is what will happen to your kids if you recklessly allow them to play Dungeons & Dragons. A movie showing the entire high school calling Robbie and his friends giant nerdlingers probably would have been more effective.
"What's in the box? What's in the box??!"
