The girl in the flower dress entered the underground temple with Skye (Chloe Bennet) during "What We Become," but viewers only got a glimpse of the newly transformed character as the targaryen mist receded. However, executive producer Maurissa Tancharoen assures fans Raina's (Ruth Negga) new identity will be reveled early in the March premiere.

"Raina has always been someone who walks into a room and knows she has all the power, and the ability to sway anything in her way," Tancharoen told Marvel.com. "Part of that is her appearance. She's always adorned herself in flower dresses, she's always perfectly put together, and she's a beautiful woman. Now we'll see how this transformation affects her."
