The season’s middle act is relentless. Terrors (Ep. 14) puts the team undercover in Belle Reve prison. Homefront (Ep. 15) traps Robin and Artemis in a deathtrap with no powers—pure tension. Then comes Failsafe (Ep. 16), a simulation episode that psychologically breaks every character, forcing them to witness each other’s deaths.
