4. Arya's scene had another hidden reference: The Rat Cook.
艾莉亞那段還有另一個指涉：鼠廚師

Feeding Walder Frey's two sons to him in a pie was actually an adapted storyline from the book series. Though Arya (and Lord Walder) aren't the key characters involved in the books, the showrunners clearly had this plan in mind for awhile. A big hint about the Freys' cannibalistic fate was given back in season three.
給瓦德?弗雷吃自己兒子的肉制成的餡餅實際是書中一個情節的改編。盡管艾莉亞（和弗雷）在書里并不是主要人物，但編劇顯然很早就設計好了這一段。弗雷家同族相食的命運在第三季就有重大暗示。

Bran Stark told the fable of the Rat Cook right after the Red Wedding.
布蘭在血色婚禮后講述了鼠廚師的寓言。

"The cook killed the king's son and cooked him into a big pie with onions, carrots, mushrooms and bacon," Bran told Meera and Jojen. "That night, he served the pie to the king. He liked the taste of his own son so much he asked for a second slice. The gods turned the cook into a giant white rat who could only eat his own young."
布蘭告訴米拉和玖健：“廚師殺了國王的兒子，和洋蔥、胡蘿卜、蘑菇和培根一起做成了大餡餅。那晚，他把餅呈給國王。國王很喜歡他兒子的味道，又要了第二塊。神把廚師變成了大白鼠，只能吃自己的小孩。”

"It wasn't for murder the gods cursed the Rat Cook, or for serving the king's son in a pie," he says. "He killed a guest beneath his roof. That's something the gods can't forgive."
布蘭說：“神詛咒鼠廚師并不是因為他殺人，或是把國王的兒子做成餡餅。而是因為他殺害了自家屋檐下的客人。神決不原諒這一點。”

Bran tells this story right after Walder Frey and Roose Bolton kill the Starks at the Red Wedding. Walder Frey gave Robb, Catelyn, and their men bread and salt, the symbol of guest right in Westeros. By killing the Starks under his roof after feeding them, Walder violated the tradition of guest right. Now, three seasons later, Walder was punished for his crime against the Starks and the gods.
瓦德?弗雷和盧斯?波頓在血色婚禮上殺害史塔克家的人后，布蘭就講了這個故事。瓦德為羅柏、凱特琳和他們的屬下奉上面包和鹽，這在維斯特洛是賓客權利的象征。請他們吃了飯又在自家屋檐下殺了他們，弗雷踐踏了賓客權利。而今，三季之后，瓦德對史塔克家和諸神犯下的罪孽終于得到懲罰。
