Ramirez says she warmed to the task of using her Tony-winning voice on the show.
"It's an amazing opportunity," she says of the March 31episode. "Singing runs in my family; it's something I embrace about myself. I've been nothing but thrilled and excited to come to work and play a character that I love and portray a journey that I'm just really excited to portray."
