The "Game of Thrones" season 4 finale has everyone muttering one word—Lady Stoneheart. Or lack thereof.

In the books by George R.R. Martin, the body of Catelyn Stark is resurrected by Thoros of Myr and Beric Dondarrion, who becomes Lady Stoneheart and goes on a murdering rampage after the tragedy of the Red Wedding.

Given the timeline of the "Game of Thrones" series, many fans expected to see the appearance of Lady Stoneheart in the season 4 finale, but she was nowhere to be found.

And it might stay that way, given the reasoning behind Michelle Fairley's absence.

"I have no idea what they plan to do about that because honestly, it just wasn’t talked about," said "Game of Thrones" season 4 finale director Alex Graves. "It wasn’t on the radar."

"I think the bottom line is that there was so much going on, at least from where I stood, that it wasn't something to get into because, you know, when you get into taking Michelle Fairley, one of the greatest actresses around, and making her a zombie who doesn't speak and goes around killing people, what's the best way to integrate that into the show?"

But will Michelle Fairley make her grand return as Lady Stoneheart in "Game of Thrones" season 5?

"I have no idea," said Graves, according to TVLine.

Unfortunately, many "Game of Thrones" observers, like Emergency Awesome, believes that Lady Stoneheart might not appear at all in the HBO series.

If Lady Stoneheart does not appear on "Game of Thrones" season 5, or ever, would you be okay with that?
