The English actress, who plays Arya Stark in the HBO fantasy series, was asked how she responded to the shocking season five finale during a Twitter Q&A.
But instead of offering up an unimaginative answer like many actors would, the 18-year-old opted to express her true feelings and fully let rip her rage:
To be fair Jon Snow was Arya's alleged half brother and "OMG STAHP STABBIN JON SNOOOO was what everyone was thinking, but it still made us giggle coming from Kit Harington's co-star.
The fun did not stop there as Williams continued to chat with fans for a further 35 minutes, replying to questions about her favourite Arya line and which character she would most like to bring back from the dead (there are a lot to choose from).
Here are some of her best responses:
Arya was left blind after being punished for killing Ser Meryn Trant but it remains to be seen whether this will be a permanent ailment or whether her sight will be restored next season.
