Reid: There's an old Buddhist saying that, when you meet your soulmate, remember that the act to bring you together was 500 years in the making. So always appreciate and be kind to each other.

Hotch: A sniper can wait up to 72 hours without sleeping. Mays: Seriously? Rossi: That's part of their training. They can stay awake for 72 hours and remain completely focused on their target. Mays: How? Hotch: By using a mental exercise called "fantasy integration". A sniper creates a scenarios involving a target that keeps that person at the forefront of their mind. Morgan: Often they'll imagine a place where they're with the target, doing something together that takes time. For example, building a car. JJ: For some, the fantasy begins the minute they're assigned a target. Then nothing will distract them.
