After Sara is relieved of duty and forced to hand in her badge, she realises she might be able to find Blanca through Instagram. She sends a message to a potential lead on Therese's account, pretending to be a friend of hers, intending to get in touch with Therese's mother. She then brings Frank to check on one of Bogdan's restaurants, thinking it might be used for drug deals. Frank reluctantly helps her, and she finds enough evidence to call her boss, who refuses to listen.

In the season finale, Waldman orders Frank to come with him to Lithuania to make a deal, as he owes money to a Latvian drug trader and has to pay off in order not to be killed. But on their way to the airport, Waldman takes Frank's phone and then tells him plans have changed.
