Game of Thrones

WARNING: This article contains major spoilers for Game of Thrones' season 4 finale 'The Children' and potential spoilers for season 5.

Fans of George RR Martin's A Song of Ice and Fire novels and HBO's Game of Thrones adaptation are up in arms yet again over a particular omission from Sunday's season 4 finale.

More so than with any other season of the show the team of writers have deviated (slightly it has to be said) from Martin's source material and now they've potentially done it once again in the tenth and finale episode, The Children.

Season 4 ends for most of the show's characters where Martin's third book A Storm of Swords concludes, so many were expecting the inclusion of a character by the name of Lady Stoneheart.

Stoneheart is the zombified Catelyn Stark – killed in last season's Red Wedding episode – who appears in the epilogue on Martin's book. Her appearance was even teased by series star Lena Headey when she posted a teasing photo on her Instagram.

Could she yet appear though? Well Headey's Instagram tease could just be a cruel and awful joke at the expense of fans, but it's much more likely that there's an element of truth to it.

Her reveal would certainly be a powerful cliffhanger so maybe the producers would rather save it for the season five premiere to drum up excitement to carry through into episodes two, three etc. It makes sense, after all, her reveal now probably wouldn't affect the hype when the show returns next year.
