Plot summary
Nancy fills in Till on Esteban's operation. Maria, fed up with Doug and in love with Andy, seduces Andy into having sex with her. As revenge for her actions, Doug calls immigration and gets Maria deported. Agent Schlatter comes to the store with a woman posing as an expecting dad; Nancy secretly informs Schlatter about the room the tunnel is in. Shane steals some of Silas' weed and starts selling it. Celia attempts to make amends with her family; Dean insists that Celia should find their oldest daughter, Quinn, and apologize to her.
While Nancy and Esteban are alone together in another area, the DEA raids the maternity store and arrests several of Guillermo's men. Till tells Nancy she will be "arrested" and then let go due to a lack of evidence. She maintains that she doesn't know who Guillermo's boss is. Meanwhile, Cesar states he obtained a report about the raid from a mole in the DEA. With Esteban's blessing, he uses the report to capture Schlatter and brutally torture him until he gives up Nancy's name. Schlatter is then killed by Cesar.
