What does Gaby really control in her life? A lot, but she doesn't panic over those areas. So why the constant panicking over those things she doesn't feel she controls? When she panics, something gets left behind or not done.

Gaby was sweating her dad learning about the scooter incident because Jenny would then learn what Gaby did. When Gaby does something stupid and gets caught, her worse fear is being so grounded she's not even allowed to race. That's the main reason she didn't want Jenny to learn about the scooter.

Gaby needs professional help before the self imposed stress causes a boatload of problems.
