Actress Leslie Grossman will return to the Power franchise as Florence “Flossie” Siegel in the upcoming prequel series Power: Origins [1, 2].

The casting decision signals a strategic expansion of the franchise's narrative universe by bridging characters from existing series into new prequel storylines. This move allows the production to capitalize on established fan interest in specific supporting characters as the broader series evolves.

Grossman previously portrayed the character in Power Book III: Raising Kanan [1, 2]. In the new series, she will serve in a recurring capacity, continuing the arc of the character Flossie [1, 2]. The decision to bring back the actress follows positive reception from viewers of the previous installment [1].

The announcement comes as the franchise undergoes a transition period. Power Book III: Raising Kanan is currently in its fifth and final season [3]. By introducing Power: Origins, the network ensures continuity for the audience while the current series concludes its run [3].

Power: Origins is designed to explore the foundations of the world established in Raising Kanan [1, 2]. The prequel format provides a mechanism to flesh out backstories that were only hinted at in earlier seasons. Grossman's return is one of the first confirmed casting links between the two shows [1, 2].

Production details for the new series remain limited, but the inclusion of Grossman suggests a focus on maintaining character consistency across the timeline. The series will further integrate the complex social, and criminal hierarchies that define the Power universe [1].

The integration of characters from Raising Kanan into Power: Origins demonstrates a shift toward a more interconnected cinematic universe for the Power brand. By reprising roles in prequels, the studio reduces casting risks and maintains viewer loyalty during the transition from the final season of one series to the launch of another.
