It sounds like the decision paid off, as Game Of Thrones viewers will get to see this real transformation of the King In The North that Harington is so proud of.
Harington admits that while he has been dissatisfied with parts of the character he has developed, he hasn’t changed them, as not to betray his instincts as to who he thought Snow was at the beginning of the series.
Harington expands to Time magazine, saying that his goal from the start of the series was to show an evolution of his character and that he feels that Jon Snow has grown more in Season 7 than any season past.
