Lena Headey Reveals What Cersei Really Thinks Of Daenerys

Contains spoilers for the season 7 finale of Game of Thrones 

It's difficult (if not dangerous) to try and figure out what's going on inside the head of Cersei Lannister on Game of Thrones. But if there's one person capable of doing it, it's actress Lena Headey.

Entertainment Weekly was on the set of the HBO series last fall during the filming of the long-anticipated meeting between Cersei and Daenerys Targaryen (Emilia Clarke), and Headey explained how Cersei felt in those moments.

"I think she's immediately envious because Daenerys is more beautiful and younger than she is and the prophecy says somebody younger and more beautiful will take her place so I'm sure that's at the forefront of her mind," Headey said. "And Tyrion is her Hand, so she couldn't be any worse."

The prophecy she speaks of is the one that a teenage Cersei first head in a flashback at the beginning of season 5. "You'll never wed the prince. You'll wed a king. You'll be queen—for a time. Then comes another—younger, more beautiful—to cast you down and take all that you hold dear. The king will have 20 children, you'll have three. Gold will be their crowns; gold their shrouds."

So far, most of that checks out. The only thing that hasn't come to pass is the part about being cast down. Of course, that's why Cersei is so worried about Dany. And the fact that Cersei has already had three children could mean grim things for her recently revealed pregnancy.
