Ready for more sibling rivalry on General Hospital? Daytime veteran Robert Kelker-Kelly has been cast to resurrect the role of Stavros Cassadine &#151 Stefan's brother &#151 beginning next month. First played by John Martinuzzi, Helena's first-born son and Nikolas's birth father "expired" after he fell down the stairs while chasing his former captive wife Laura and Luke Spencer. "The return of Stavros Cassadine, at a point when the Cassadine/Spencer feud is at the boiling point, will have explosive consequences in this generational and historical story," says GH executive producer Jill Farren Phelps. "The role of Stavros is hugely pivotal to the current story, and Robert's talent and charisma will make Stavros's homecoming even more dynamic."
