Ned Stark (Sean Bean) was one of the most honorable characters on HBO's "Game of Thrones." When he was killed toward the end of the first season, fans were shocked, and it set the tone that no character is safe. The idea of a prequel series and flashbacks in Season 6 have been thrown around recently, and many are wondering if this means viewers will once again see Ned. Bean suggested it's possible he could return, but he's unsure of how it would work.

In a "Larry King Now" interview released Wednesday, King asked Bean a question from a fan, who wanted to know if he would ever consider playing Ned in a prequel series. King suggested if not for a prequel series, maybe Bean could come back in a flashback scene. Bean agreed, but he didn't seem too confident he would. (The video can be seen on ComicBook.com.)

"I don't know; there's been talk of Ned Stark coming back. I don't know how he could come back, maybe as a zombie in retrospect," Bean said.

Bean later added that HBO would probably look for a younger actor to play him in a prequel series about Robert's Rebellion. It wouldn't be the first time HBO has used a younger actor to reprise a role as the network has reportedly cast a young Ned Stark for "Game of Thrones" Season 6. In August 2015, “Game of Thrones” community blog “Watchers on the Wall" reported that 13-year old Sebastian Croft would play the role of Ned in "Game of Thrones" Season 6 for a flashback scene.

The flashback many are hoping to see is the infamous Tower of Joy scene where Ned's sister, Lyanna Stark, died in the final hours of King Robert’s (Mark Addy) rebellion, but not before she could tell her brother a secret. Some believe the secret could be that she had a baby boy, Jon Snow (Kit Harington), with Rhaegar Targaryen, and she entrusted Ned to protect her son.

Bran Stark (Isaac Hempstead-Wright) returning for Season 6 has also fueled speculation that an answer to who Jon Snow's mother is could be coming in the near future. In an interview with Entertainment Weekly, Wright said Bran will start to control the visions he has, which could connect the past and present.

"Now we’re given looks into very important events in the past, present and future of this world, and Bran is beginning to piece them together like a detective, almost as if he’s watching the show," Wright said. "Equally, he’s now discovering how crucial he could be in the Great War."
