No. We was attacked by Lannister men. Yoren and the rest were killed, but some of us escaped it. Me, Arya, some others. There's a whole tale of it, but she didn't die in King's Landing or at all, so far as I know.

[No, as far as he knew, she was wed to Ramsay Snow, who was reputed to have let his last wife starve to death after eating her own fingers. But Gendry was not so cruel as to tell Robb Stark what his failure cost his family. Or how close Arya had been to meeting him at Riverrun.]
