 Now before any of you go posting "how did Cheetah Kid get there so fast", consider this:

1. Cheetah Kid is (as you might have guessed) part cheetah. Meaning he can run at the average speed of a cheetah and a human. If you do the math, that's 45.5 mph.
2. He knew Bright Eyes wasn't too far away because of Helena's stupidity.
3. He heard the gunfire, which pretty much gave away Bright Eyes' exact location.
