Ep 6. Command: Delete

Elementary season 7 episode 6, titled "Command: Delete," follows the story of Sherlock Holmes (Jonny Lee Miller) and Dr. Joan Watson (Lucy Liu) as they investigate a homicide case involving a high-tech company. The episode begins with Watson trying to help an ex-con named Tyus Wilcox, who is falsely accused of stealing from a company named Speckles Systems, a technology firm that specializes in facial recognition software.

Even though Wilcox denies stealing anything from Speckle Systems, he is caught on the company's CCTV camera entering and exiting the building. Sherlock and Watson realize that the only way to clear Wilcox's name is by investigating the company and trying to find any flaw in their security system that could have been exploited by the real culprit.

As they start delving deeper into Speckle Systems, they discover that the company's facial recognition software is being used for nefarious purposes by a group of hackers who call themselves "The Collective." The Collective hacks into the company's software and uses it to blackmail people by threatening to release their private data.

During their investigation, Sherlock and Watson discover that the Speckle Systems' CEO, Raymond Carpenter, had some knowledge of The Collective's actions. They also come across a former Speckle Systems employee who confirms their suspicions.

The episode takes a surprising turn when The Collective's leader, who goes by the name "The System," reaches out to Sherlock through an encrypted messaging system. The System asserts that he can save Wilcox from going to jail if Sherlock helps him destroy the facial recognition software's current version. Sherlock is initially hesitant but decides to pursue the offer when he realizes that the software can easily be used to violate people's privacy in dangerous ways.

As the episode progresses, Sherlock and Watson work alongside The System, who helps them get into Speckle Systems' central server and upload a virus that destroys the facial recognition software. The deletion causes a major security breach at the company and reveals that Carpenter was using the security system to track the movements of his rival.

In the end, Wilcox is cleared of all charges, and The Collective's hacker group is disbanded thanks to Sherlock and Watson's efforts. The CEO is arrested, and Speckle Systems is left scrambling to rebuild their damaged reputation.

Overall, "Command: Delete" is a thrilling episode that tackles the issue of privacy invasion. The episode also showcases the strong bond between Sherlock and Watson, as they work together to ensure justice is served. It's an action-packed adventure that will keep viewers engaged until the very end.
