Silas draws up a new plan to start a legal medical marijuana business with Doug, which Nancy funds.

Quinn's attempt to extort money for Celia's return to her friends and family fails miserably, since none of them are willing to pay any ransom.

Silas' medical marijuana shop is raided by the police, and he and Doug lose all of their pot in the process; they turn to Dean to help reclaim it.

Celia's story arc concludes with her forming her own team consisting of Doug, Dean, Sanjay, Ignacio, and Isabelle to sell marijuana—a deliberate echo of Nancy in season one.

Esteban becomes the front-runner for governor despite Pilar's rejection, but he is arrested for suspicion of conspiracy, racketeering and tax evasion.

Pilar reveals to Nancy that she is aware of her actions involving Guillermo, and suggests that the apparent accidental deaths of Shane and Silas would generate a sympathy vote for Esteban.

This is the last season Elizabeth Perkins and Allie Grant appear in, as Celia and Isabelle Hodes respectively.
