Episode Summary & Review
Summary
Young Justice takes on its most dangerous enemy after they discover who within the team is the traitor.
Our Take
A genuinely satisfying finale that pays off a full season of setup, with the traitor reveal landing harder than most shows manage. The mind-control premise lets every hero clash in ways we haven’t seen before, and the final stinger is a gut punch that reframes everything. It’s a dense, fast hour, but it earns every minute. Watch it.
