Young Justice launches a full-scale attack on the All-Purpose Espionage Squad (A.P.E.S.) to save Secret! Even if they win, it could lead to some very bad times ahead...especially after the press gets wind of what YJ does to Mount Rushmore!
Note: At some unspecified point between issues, Superboy is replaced and impersonated by his clone Match as a lead up to the Sins of Youth storyline. A conversation from last issue is later referenced by the real Superboy (indicating that it was actually him in that issue), and Match's actions in this issue are brought up as evidence that he is an imposter. Therefore, while we never learn exactly when Match infiltrated the team, we can know for certain that he is pretending to be Superboy from this issue until the real Superboy returns in issue 20.
