- "He reached out to an arms dealer I had on a watch list. He's got two priors and wants to avoid a third, which is a problem because we just caught him with 10,000 rounds of military-grade ammo."
"Jack DeLeon. Yeah, I heard about it."
"Castle is the buyer. I guess he needs bullets for all those guns he stole from the Greeks."

DeLeon was caught by the United States Department of Homeland Security with 10,000 rounds of military-grade ammo.
