The most hated House in Game of Thrones could be returning

A new character could have a big impact.

Still haven't seen Season 7 of Game of Thrones yet? What, seriously?!?! There are still people like that out there in the realm?! Ok, consider this to be your spoiler alert. It seems like a long time ago since that wait for the new season came to an end but for House Frey, they probably wished that Season 7 didn't arrive at all because as well know, "Winter came for House Frey." This being said, every Game of Thrones fan must have been screaming with delight after Arya Stark finally avenged the Red Wedding and the murder of her family. It was that incident which cemented Walder Frey and his sons as Public Enemy Number One in Westeros for the Starks. Jon and Sansa demolished House Bolton after the Battle of the Bastards, their younger sister did the damage to the Freys. It's cold in The North but Arya's revenge was colder than a White Walker in January. After killing, cooking and feeding Walder Frey's own sons to him, Arya gleefully slit his throat and smiled over his bleeding corpse. She wasn't finished yet. Prior to the credits rolling on Season 7, Arya poisoned the remaining members of House Frey but the Great House of the Riverlands might be striking back. According to fansite Watchers On The Wall, Irish actress Danielle Galligan is set to play a character called Sarra in the show's upcoming eighth season. The only known mention of a Sarra in the A Song Of Ice And Fire book series is Sarra Frey, a granddaughter of the hated Walder Frey. Will the most-despised family in Westeros be returning? We wouldn't put it past Walder Frey to have the last laugh, even though he's dead.
