Part of devoting nearly eight years of Sunday nights to an epic show like Game of Thrones means watching not just your favourite characters, but the young actors behind them grow up right before your eyes .

(If you need even more of a reminder of how much Arya has grown over the past seven seasons, look no further than last night's sex scene .)
