戲裡Arya已經年滿18，戲外Maisie Williams早已經22歲了，所以都沒問題，不過HBO跟她本人都還是得出面澄清一下：

HBO Clarified Arya’s Age Before Airing ‘Game of Thrones’ Sex Scene, Plus Maisie Williams Reacts

HBO發的推文還蠻有好玩的：

By age 18 in Westeros you should have:
- Had a pet.
- Moved out on your own.
- Travelled extensively.
- Had a kill list.
- Pretended to be the opposite sex to evade capture.
- Been blind for a while.
- Ticked at least three people off of your kill list.

全都是Arya這幾季以來的冒險經歷啊......
