disclaimer; I don't own the Labyrinth, or any of its characters.

When the first runner after Sarah broke down into hysterical tears after two hours of alternately pleading with and making demands at the determinedly closed gates of the Labyrinth, Jareth thought nothing of it. Some people really were just that weak – not everyone could be a Sarah Williams, after all.

When the second runner after Sarah spent three hours trying to coax the gates open, and the rest of the ten hours searching for an alternate entrance (that didn't exist), Jareth's opinion of mortal intelligence dropped drastically.

When the third runner after Sarah was trapped at the gates for two hours, Jareth grew suspicious and opened the gates himself. The runner, upon crossing the threshold of the Labyrinth, promptly fell into an oubliette.

When the fourth runner after Sarah was presented with an infinite number of gates to pass through before she could enter the Labyrinth proper, Jareth realized something had to be done.

The Labyrinth was clearly sulking.

And it was all Sarah's fault
