The Night King, pioneer of the White Walkers, will require all the assistance he can get the chance to win. Will he resuscitate the dead bodies in the Winterfell graves as fortifications.
The hypothesis likewise relies upon whether the Stark bodies are covered at Winterfell all. In the A Song of Ice and Fire book arrangement, Catelyn’s body was dumped in the stream before she was at last breathed life into back as Lady Stoneheart (who despite everything we would like to see before the show closes!).
Robb’s body was profaned by the Freys after the Red Wedding. In any case, after the Battle of the Bastards, the Starks covered Rickon beside Ned in the Winterfell graves.
Some analysts on Twitter Reddit still recommend Arya might keep running from non-Starks. One proposal is The Mountain (AKA Ser Gregor Clegane), maybe sent by Cersei Lannister.
Different watchers think they see Jaime Lannister or Samwell Tarly. Another probability is an undead Petyr Baelish, whom Arya executed with his own knife in Season 7.
