Agent Quesada and Agent Alonzo speak with Nathan, who is upset that they are at his office. The agents ask Nathan to wear a wire when he goes to speak to Mr. Linderman. Later, the two listen to Nathan in the Corinthian Casino; Quesada thinks it must be hard to act natural in his situation. Suddenly, Jessica shows up and has them hand over their weapons. She then aims her gun at them and kills them both.
