The character made her debut in the current, and historic, 21st season, as a vice cop who helped Captain Olivia Benson (Mariska Hargitay) and her team take down a media mogul suspected of rape in a sting operation. Azar-Tamin then transferred to SVU and helped on a few more cases. Now, she'll replace Det. Dominick Carisi (Peter Scanavino), who made the leap to the District Attorney's office earlier this season.

Law & Order: Special Victim's Unit airs Thursdays at 10/9c on NBC.
