The Mentalist has returned for the rest of its last season on Wednesday on its new timeslot, and fans were eager to find out what happened to Patrick Jane and the rest of the team in a case that involves a "botched DEA raid."

The last episode of the Mentalist saw how Teresa Lisbon (Robin Tunney) and Patrick Jane (Simon Baker) tried to uncover the mysterious death of an officer's wife. This week, the pair works on finding out the truths behind a failed DEA raid and how an FBI agent tries to cover up the misdeeds of the bureau.

The synopsis for the next episode reads that it will focus on a certain Agent Dennis Abbott (Rockmond Dunbar) as he tries to dig deep into a failed DEA raid. His investigation is interrupted by his former boss who wants him to keep the agency's wrong doings to himself or his career will be on the line. Now, Agent Abbott is torn between securing his career, or being true to his morals as an agent.

The episode called "Green Light" is a huge return for the show, with fans eagerly awaiting what will happen to Abbott in case Jane and Lisbon finds out that he is hiding important information about the DEA raid. Could the raid have failed because of incompetent officers on the field?

Meanwhile, cast member, Tim Kang, revealed some information on his social media account about the development of the show's last season. Kang posted that the series finale has already finished shooting. Though fans wouldn't be pleased to know that the final episode has already wrapped up, it will surely be an explosive episode that will give the acclaimed series a rightful ending.

TV Line has reported that on the final episodes, the CBI team will try to catch a serial killer named "Lazarus," who will wreak havoc during the final stretch of the series.
