NBC's Law & Order: Special Victims Unit, Season 2, Episode 19 remains as one of the standout episodes to date.
Episode 19, titled Parasites, opens to a gritty crime scene when a construction crew finds a dead body with a leash and a collar. Stabler and Benson step in, and from that point on, nothing about the case neatly fits. It looks simple at first. A young Romanian woman, Ava Parulis, is believed to be the victim. But as the detectives push deeper, they unravel more secrets.
Benson and Stabler speak to Ava's twin sister Irina, who seems to be broken but steady enough to speak. Their past reveals itself as the woman confesses. What nobody expects is the turn the case takes. Irina isn't Irina. The woman alive is Ava. The woman buried is Irina. The switch is born out of fear and guilt. It turns messy and emotional. Turns out Ava wanted to get Oksana out of a prostitution circle, and that she had to take such steps to gather the amount.
As the detectives close in on the truth, Razvan Toscu, a diplomat and Irina's murderer, believes his immunity shields him from the consequences. Ava reveals that Toscu wanted to kill her, but he killed Irina instead. Ava was left with no other choice but to swap identities and bury her sister in the backyard. In the end, Toscu was arrested for his crimes, and Valentina's human trafficking ring was finally taken down. Here's who plays whom in the episode.

Why is the cast of Law & Order: "Parasites" perfect?
Parasites, the episode, hits hard because it doesn't dress tragedy. It delves into a murder case that unravels secrets, including an identity exchange, a prostitution circle, and a desperate story of survival. The case isn't built around a shadowy serial killer or a sensational twist. Instead, the hour follows detectives who slowly untangle the life of a woman acting out of fear, duty, and desperation. Ava stepping into her sister's identity is legally indefensible, but the episode never treats her as a villain. Her choices come from panic and a fierce instinct to shield her family. That moral gray zone is what gives the story its weight.
The casting of Law & Order: Special Victims Unit, Season 2, Episode 19 makes that complexity land. Each cast member of Law & Order: Special Victims Unit, Season 2, Episode 19, from the regular squad to the guest stars who carry the emotional weight, grounds the drama into something that feels painfully real.
