"I think Donna's always busy. Her dance card is full," she said. "I think it was interesting that when we left off at the end of season six, she was turning that attention that she's put into everybody else's emotional and professional lives, she's going to turn some attention onto hers and try to figure out what she wants to do. So when we come back, she's digging into that."

The show, which just wrapped production on its landmark 100th episode, also stars Patrick J. Adams, Meghan Markle and Rick Hoffman. In the season premiere, Adams' Mike will finally return to the firm as a fully-fledged lawyer while Louis (Hoffman) manages the new class of associates and Donna and Rachel (Markle) find their places in the new world order following Jessica's (Gina Torres) departure. Dule Hill joins the series in a season-long arc as Alex Williams, a longtime friend of Harvey's who is currently a senior partner at rival law firm Bratton Gould.
