Complications

"Complications" is the 16th episode of the second season of Young Justice, and the 42nd of the overall series. It aired on February 16, 2013.

Logline
Black Manta gives Miss Martian twenty-four hours to live, but that may be more time than Aqualad has with Sportsmaster and Cheshire on the hunt for his head!

Title
Several complications arise, hence the title. The first is M'gann having restored Kaldur's mind but now the two and Artemis having to figure out how to allow M'gann to escape. The second is Sportsmaster and Cheshire raiding the Manta-Sub and the others having to deal with their presence. The third is Nightwing deducing that Blue Beetle had become an agent of the Reach and was responsible for the Team's disappearance from the Warworld, but now needing to figure out how to resolve the situation, given that the Ambassador has since declared to the world that Blue Beetle was responsible for shutting down the Warworld.
