Dr. Spencer Reid:
I notice you don't carry a gun.

John Blackwolf:
Twenty-one feet.

Dr. Spencer Reid:
What?

John Blackwolf:
Ask Agent Hotchner there. He's the real gun hand.

Aaron "Hotch" Hotchner:
Why do you say that?

John Blackwolf:
You carry two guns.

Aaron "Hotch" Hotchner:
The maximum distance an attacker with a knife can close in the time it takes to react, draw your sidearm and fire is twenty-one feet.

John Blackwolf:
Inside twenty-one feet, I win. Outside twenty-one, I have other options besides shooting a man.

Dr. Spencer Reid:
Like negotiating.

John Blackwolf:
Like running.

Aaron "Hotch" Hotchner:
Why do you say I carry two guns?

John Blackwolf:
Your right instep footprint's heavier than your left. And since you don't appear to have a clubbed right foot...

Aaron "Hotch" Hotchner:
You can't tell that from my footprints. There's no perceptible difference.

John Blackwolf:
Your problem isn't with your prints. It's with your perception.
