Did Lena Headey Reveal Major Game of Thrones Season 4 Finale Spoiler?

Lena Headey portrays the icy and deliciously evil Cersei Lannister on HBO's Game of Thrones. The actress also seems to enjoy posting subtle, or sometimes not-so-subtle, spoilers about the show. Those who have read the books can likely pick up on these cues, but those of us who haven't might take them as nothing more than innocent social media posts.

[WARNING: MAJOR GAME OF THRONES SERIES AND BOOK SPOILERS BELOW!]

Consider this image she posted on her Instagram account about two months ago:

It looks like she's just goofing around with fellow actor Pedro Pascal, but we now know it foreshadowed Oberyn Martell's gruesome death at the hands of The Mountain in the latest episode.

So then what does this image, posted one month ago, mean?

It's just a photo of some rocks arranged in the shape of a heart. Those who have read the books should recognize this "stone heart" as a sign that Lady Stoneheart, aka a resurrected Catelyn Stark, will likely make her appearance on the show before the season ends, most likely in the finale given that the next episode will probably take place entirely at Castle Black.

In the books, Thoros of Myr brings Cat back to life much like he does continually for Lord Beric Dondarrion. But Cat's body has been dead for so long that Beric must sacrifice himself for good in order to bring her back to life. Cat then becomes the leader of the Brotherhood without Banners, renames herself Lady Stoneheart an swears vengeance against anyone involved in the Red Wedding.

This is a particularly controversial development in George R.R. Martin's books, one that a significant portion of fans dislike. Many book readers wondered when this moment would come, and it looks like we'll see it in the Season 4 finale if Headey is in fact teasing us again.

Do you want to see Lady Stoneheart come to the show? Is it too early for it to happen? Is Headey spoiling the plot for us again? Let us know in the comments below.
