After this, the villainess shoots and kills Paco.
In the episode's climax, Jane meets Krystal on another date on a yacht, and it is there that he reveals that he has figured out that Krystal is the mysterious "Mr. X," who has been running the Gulf Coast Ring. After boldly admitting to killing Paco, the evil Krystal pulls out a gun with intent on killing Jane, only for Jane to reveal that he had the FBI on his phone and they listened to the entire conversation.
