Leslie Grossman to Reprise Flossie in Power: Origins, a Prequel Set After Raising Kanan’s Finale

Starz’s Power universe is expanding its timeline again, with Leslie Grossman set to return to reprise her role as Florence “Flossie” in the upcoming prequel Power: Origins, according to an exclusive report from Deadline published on August 18, 2026. The casting news comes as the franchise follows the aftermath of the Power: Book III Raising Kanan series finale, with the new prequel moving forward from that point in the story’s chronology.

Grossman, who previously played Flossie in Raising Kanan, will recur in Power: Origins, the report says. The new series is described as picking up after the events of Raising Kanan’s finale, a framing that places her character within a later chapter of the prequel’s expanded narrative rather than a flashback-only role.

Deadline’s report also characterizes the announcement as a return of a familiar figure for viewers who “left you wanting more” after Raising Kanan. In that context, Grossman’s involvement is positioned as a continuation of audience attention around Flossie, whose earlier appearances were part of the prequel spinoff’s broader cast and story arcs.

The report does not provide additional casting, episode count, or production timeline details beyond Grossman’s recurrence. It also does not specify how large Flossie’s role will be within Power: Origins, beyond indicating she will appear again in the prequel series.

Power: Origins is expected to further develop the franchise’s backstory and character history, building from where Raising Kanan’s storyline concluded. Within that structure, bringing back Grossman means Flossie remains a bridge for viewers between the earlier character dynamics established in Raising Kanan and the next wave of storytelling in the new prequel.

For the production and distribution side, the addition of a returning lead among the franchise’s continuing cast is a continuity step that can matter for audience retention and series branding across the streaming and cable marketplace. It also reflects the franchise’s reliance on recognizable characters to sustain interest between releases in a long-running IP.

Grossman’s casting as a recurring character in Power: Origins underscores that the Power franchise is continuing to rely on established performers as the series iterates on its narrative structure. Deadline’s report is the first published confirmation in this discovery set, and it is the key reference point for what has been announced publicly about her role at this stage.
