Plot summary
The team works with MI6 to infiltrate the United Nations headquarters in New York City to stop Jonas Madaky, an ambassador/gun runner from the African nation of Buritan, from making a deal to supply militants with weapons to destroy their rebellious revolutionaries. However, things take a bad turn when the British operative turns on the team and blackmails Scorpion into helping assassinate Madaky. It appears that MI6 agent Gleason is killed and that the team decides to carry out the plan to take out Madaky. It is later revealed that Gleason is alive and Scorpion played a Houdini stunt.
They orchestrate Madaky's arrest and reveal that MI6 director Olivia Cromwell was in business with Madaky, leading to her arrest, as well. On the home front, Walter gets a court order to have Megan intubated, much to Sylvester's dismay. In order to protect Megan's wishes, Sylvester makes a bold decision and gets Ray, an ordained minister of the Immaculate Church of the Internet, to marry them, making Walter accept that the situation is beyond his control.
