Davis will appear in the hour scheduled for April 24 that explores violent youth and will play Viola Mesner, the mother to a troubled boy named Henry (Shameless' Ethan Cutkosky).  

"Julie Martin and I co-wrote this one; it's a tough episode about a mother who confronts the possibility that her 10-year-old son is just … wired wrong," Leight tells THR. "We sent it out to Hope and I crossed my fingers because I really couldn't think of anyone else who could play it. Working with Hope on In Treatment was one of the great joys of my career. I'm thrilled I get to work with her again."

In addition to In Treatment, the actress -- who has been fielding multiple pilot offers this season -- most recently has appeared in The Newsroom, Mildred Pierce and The Special Relationship, where she portrayed Hillary Clinton. She's repped by UTA and Kipperman Management.

Law & Order: SVU, which is also prepping an episode about "legitimate rape" with Homeland's David Marciano and The Walking Dead's Lauren Cohan,airs Wednesdays at 9 p.m. on NBC.
