Labyrinth Response

In Greek Mythology Labyrinth is a place where it was supposed to hold and capture a Minotaur(half man and half bull). But it was built so cunningly that the designer himself couldn't escape after he had built it. In THE BEAST, chapter 12 is labeled "Labyrinth".Why?
In the book Gabi and Spoon are trapped in a "labyrinth" because they are having all these problems and it feels as if they can never get out. Gabi is using drugs, she says that one day everything seemed so clear in her life and after Spoon left for Wallingford everything started to fall apart. After a few months Spoon came back and found out what was happening. He tries to comfort Gabi,trys to understand her but can't. Spoon finds out Gbi does drugs and he gets trpped in the "labyrinth" with Gabi. Now Spoon is trying to find away to get Gabi out of doing drugs and for both of them to escape out of the "labyrinth". The labyrinth is their problems.
