Agent Petty's revelation tests the loyalties of Marty, Ruth and the cartel. Despite the FBI closing in, the Snells refuse to destroy their poppies.
The FBI finds Charlotte's half of the $10,000 she took, which Roy brings up during Marty's interrogation in the hopes that he will turn informant. Roy also informs him that Ruth tried to kill him by wiring the dock the same way she did when she killed her uncles. Roy makes Ruth look like an informant, and Helen asks the Byrdes whether she can be trusted. Marty hesitates before saying yes, then races to the Langmores to warn Ruth.
Ruth admits she tried to kill Marty, but says she will not try again because circumstances have changed, so he vouches for her to Helen, but Helen's associates subject Ruth to waterboarding interrogation. Ruth does not crack, and Helen tells Marty she is impressed with Ruth's willpower. Marty reminds Wendy that she cheated on him, and Charlotte overhears and informs Jonah. Charlotte and Jonah discuss using what is left of their money took to buy a van and run away. Helen tells the Snells to burn their poppies so Roy will not find any evidence, but Darlene resists. Wendy brings Darlene adoption information, which is a ploy to enable Buddy to gain access to the Snell farm and burn the field.
