It’s never too late to become an internet sensation ā€” just ask the 87-year-old Olenna Tyrell cosplayer.

After stealing the show at Dragon Con by dressing up as the Game of Thrones fan favorite (played on the show by Dame Diana Rigg), the image of the unnamed grandma rocking the full wardrobe with an “It was me” sign and sitting on an Iron Throne wheelchair swept the internet. Now, the GoT granny is back online with an adorable reaction to her newfound fame.

“I think it’s wonderful because it really makes me fill my place,” she shared in a video recorded by her granddaughter. “I’m a good actress.”

In the clip, the woman, who has accompanied her daughter and granddaughter to four consecutive Dragon Cons, is shown all the love she’s getting online, including from EW. “I don’t deserve all that faith they’re giving me, but I love it,” she said, before giving fellow prospective elderly cosplayers some advice: “Go to it gang, while you’ve got nothing to lose.”

Of course, she couldn’t sign off without re-enacting Lady Tyrell’s epic pre-death confession to the murder of King Joffrey. “Tell Cersei, it was me,” she declares with a truly scary evil laugh.
