In Harry Potter and the Goblet of Fire (2005), during the hedge maze, you must have quick reactions otherwise you can get taken out by sudden traps.
Both Harry and the other Hogwarts contestant are shown below:
They have to run to make it to the portkey to avoid being swallowed by the maze walls.
The portkey, the blue light behind the two, is the one that took the two to Voldemort.
Why did this portkey take the two to Voldemort when the other portkeys took other contestants back to the start?
