The next target on the Blacklist is the physical embodiment of both. He's known as the Courier, and his involvement in a transaction virtually guarantees its success. Once he's hired to make a delivery, he can't be bribed, he can't be stopped. If either party attempts to double cross the other, he kills them both. The perfect middleman for an imperfect world.
No, I mean you don't understand him. Our old man knocked us around when he needed to, which didn't bother Tommy. But dad hated that. Felt like he couldn't control his own son, and he couldn't. So when he was 11, dad started hosting these dogfights. Not with two dogs, but with a dog and Tommy. Well, we had this barn. People would come from miles around. They'd get drunk and make bets. What it did to him over time...Tommy's broken. Somewhere in his head, a switch flipped. I wish I could help you, but you know how it goes. You're here because somebody screwed up. The deal went sideways. And now the buyer and seller have targets on their head, if they're not dead already.
