Performance

December 22: The Team goes undercover at the Haly International Traveling Circus to locate a thief stealing weapons technology across Europe with Agent King Faraday suspecting that Jack Haly's circus performers are responsible.

December 23: The experience of working with the circus again drives Robin to distraction as he reflects on his family's death and the possibility of Jack Haly losing the circus if the thief isn't caught. As the circus moves location, the Team encounters the thief: Parasite. Superboy starts to rely on Lex Luthor's 'Shields' more.

December 24: The Team track down Parasite and defeat him with Parasite being arrested by Agent King Faraday. Afterwards, Jack Haly reveals to Robin that he knows and remembers him, and implores the Boy Wonder to perform for the circus one more time.

In Young Justice, being a teenager means proving yourself over and over- to peers, parents, teachers, mentors and, ultimately, to yourself. But what if you're not just a normal teenager? What if you're a teenage superhero? Are you ready to join the ranks of the great heroes and prove you're worthy of the Justice League? That's exactly what the members of Young Justice- Robin, Aqualad, Kid Flash, Superboy, Miss Martian and Artemis- will find out, whether they have what it takes to be a proven hero.
