Shades of Blue Sneak Peek: Watch Harlee and Wozniak Battle as She Reconsiders Her Loyalty

With Saperstein (Santino Fontana) dead, Wozniak (Ray Liotta) proved he'll stop at nothing to protect the house he's built. Early in Thursday's episode, he keeps his squad in the dark about how Saperstein really died, and keeps them in check with a rallying speech about their "brand of justice." But, knowing the real ruth, Harlee (Jennifer Lopez), has a final crisis of conscious about Woz's ways before she confronts the man she once trusted completely -- and then commits to helping Stahl (Warren Kole) with his investigation.

Check out Woz and Harlee's tense tango in the clip below.

Shades of Blue airs Thursdays at 10/9c on NBC.
