Leslie Grossman will return as Florence "Flossie" Siegel in the upcoming Starz prequel series Power: Origins [1, 2].
Grossman's return signals a continuing expansion of the Power universe, leveraging popular characters from previous installments to build audience anticipation for the new prequel.
Grossman previously portrayed the character in Power Book III: Raising Kanan [1, 2]. The actress will now appear in a recurring capacity in the new series, continuing a storyline that extends beyond the events of the previous show [1, 3].
This casting follows the conclusion of Raising Kanan's fifth and final season [3]. The decision to bring back the character of Flossie was driven by audience demand and the desire to further explore the narrative roots of the franchise [1, 2].
Sascha Penn, the creator of Raising Kanan, said the character is returning to the screen. "It wasn't even my idea," Penn said [3].
Power: Origins will air on Starz as part of the broader franchise's effort to detail the early history of its central figures [1, 2]. The series aims to provide deeper context to the established lore, while introducing new dynamics to the criminal underworld depicted in the series.

The return of Grossman demonstrates Starz's strategy of using 'legacy' characters to anchor new spin-offs. By bridging Power: Origins with the concluded Raising Kanan, the network reduces the risk associated with a new series by providing a familiar point of entry for existing fans.
