Dragon Con 2017 found the most savage grandma of all time: an 85-year-old woman dressed as The Seung Ha (승하) ArchivesQueen of Thorns a.k.a. Lady Olenna Tyrell of Highgarden from Game of Thrones.

We can all go home now; I've found the best #Cosplay at #dragoncon2017

She even rolled around the Atlanta, Georgia convention in a wheelchair-turned Iron Throne with an "It was me" sign. It was a nice wink to the momentous scene where Olenna tells Jaime it was she, not Tyrion Lannister, who poisoned his son Joffrey right before drinking the poison that gave her a painless, peaceful death. Savage.

And to top it off, she even wore "deal with it" Thug Life glasses, elevating her outfit even more. She also held up other signs like "not dead yet."

Many attendees stopped by to photograph the epic outfit.
