Spoiler alert – people will die in Season 5 of “Game of Thrones.” Ok, maybe that is not much of a spoiler considering no show is more famous for its willingness to lose characters. However, author George R. R. Martin revealed that the new season’s shocking deaths might be even more surprising than usual.

On the Red Carpet for Saturday’s Writers Guild of America Awards, Martin told Showbiz 411 that, “People are going to die who don’t die in the books, so even the book readers will be unhappy. So everybody better be on their toes.”

With even readers of the “Song of Ice and Fire” book series in the dark, fans are left to speculate which characters will meet their end in Season 5. Who will be the next to go? Here are four possibilities for Season 5’s surprising deaths:

1. Petyr Baelish

Lord Baelish (Aidan Gillen) has managed to survive all of the published books so far -- despite being one of the most backstabbing men in Westeros. However, that is no guarantee that Littlefinger will not meet his end on the show. Sophie Turner, who plays Sansa Stark, recently revealed that she has a particularly traumatic scene coming up and that moments in the new episodes will be more shocking than even the Red Wedding. This could lead fans to speculate that Baelish will be the one to go as Sansa tries to free herself from their creepy, controlling relationship.

2. Robert Arryn

The strange son (Lino Facioli) of Lysa Arryn (Kate Dickie) is the only other character of note that could fall victim to Sansa’s traumatic scene. Baelish has already displayed a willingness to kill Eyrie royalty before – via some cold Moon door pushing – and Sansa has been willing to cover it up in the interest of her survival. Will the young lord be their next victim?

3. Alliser Thorne

Ser Alliser (Owen Teale) is still alive and kicking the book series, but the last fans saw of the character on the show he was injured at the Battle of Castle Black. Perhaps the stubborn veteran will succumb to his injuries. It seems like a change in leadership is coming at the wall – cough, Jon Snow (Kit Harrington) – and it might be time for the character to make his exit.

4. Mance Rayder

Jon Snow convinced Stannis (Stephen Dillane) to temporarily spare the life of the King North of the Wall (Ciarán Hinds) at the end of Season 4, but will the act of mercy last? Mance is a stubborn man and will likely not be an agreeable prisoner. Plus, Stannis, under Melisandre’s (Carice Van Houten) influence, has proved a willingness to kill pretty much anybody. Will Mance be the next to go?
