'Shades of Blue' First Look: JLo's Harlee is 'Not a Good Person'

On Shades of Blue, Jennifer Lopez’s Det. Harlee Santos — a corrupt cop turned reluctant FBI informant — is just trying to keep it all together, but the cracks are starting to show in her tough facade.

In this clip from Thursday’s new episode, Harlee is keeping a vigil at the hospital, where her fellow detective Saperstein (Santino Fontana) is barely clinging to life after being attacked by Wozniak (Ray Liotta). ADA James Nava (Gino Anthony Pesi) stops by to offer Harlee a shoulder to cry on, but she tearfully cautions him against getting too close. “Never fall for someone if you don’t know who they are,” she says. “I’m not a good person.”

Harlee’s guilt isn’t going anywhere, given that Wozniak still thinks Saperstein is the rat and plans on finishing what he started as soon as he gets a chance.

Shades of Blue airs Thursdays at 10 p.m. on NBC.
