Arya kills the Night King, ‘Game of Thrones’
Arya Stark has proven that she is the greatest Stark and one of the most powerful characters in the series. All those years of training finally pay off when she tenaciously stabs the Night King just before he was about to kill Bran. Although it is unclear how she managed to sneak past the army of White Walkers, it is possible that she used her Faceless Men skills to disguise as one of them.
