Game of Thrones actress Lena Headey showed up to her Jimmy Kimmel taping yesterday sporting a rather cheeky tank top with the words “I’m not sorry” captioned inside a heart. The shirt is a reference to a photo Headey posted on her Instagram account of a pile of stones shaped as a heart, which Headey had captioned, “my stone heart.” (It wasn’t her only winking Instagram nod to the show.) Most Game of Thrones book fans (including myself) interpreted the photo as an allusion to a book character called Lady Stoneheart and clung to it as confirmation that Stoneheart would appear on the show. The fact that she did not appear left many book readers howling with disappointment and, because of a single photo, some people even tried to blame Headey for getting their hopes up.

Which is ridiculous, of course. It’s silly to even call what Headey posted a “spoiler,” when that pile of stones doesn’t make sense to anyone without context from the book or an all-knowing friend. But, regardless, Headey refuses to be your patsy. During her appearance on Kimmel, when Headey was asked if she was being intentionally provocative with the photo, she played innocent, claiming, “No, that was me drunk in Palm Springs going, ‘This is so pretty.’” Her snarky shirt, on the other hand, tells a different story. She’s not responsible for your pain, Lady Stoneheart fans, but she’s also not sorry to have messed with you in the first place. How Cersei of her. Headey went on to record a fun segment with host Jimmy Kimmel where they swigged wine, Lannister-style, and traded Game of Thrones-esque insults. Because Kimmel is no Tyrion, Headey unquestionably won this battle of wits. I could watch her cruelly over-enunciate all day.
