S6E09 Explained – update #3 (Patreon)

In this episode, Tormund mentions that "Jon Snow’s not a king" – which is kinda funny, given that there's actually heaps of foreshadowing in the books that Jon will become a king:

In several chapters, Jeor Mormont's raven repeatedly says "King" at Jon

In the ADWD Prologue, Varamyr says that warging into Ghost would be "a second life worthy of a king" – and it looks likely that, in the books, Jon will warg into Ghost before his resurrection

In AGOT, King Robert makes an odd comment about kings "hiding under the … Snow"

Additionally, we know Robb wanted Jon to succeed him as King in the North (Catelyn V, ASOS). And of course there's the whole loophole of death freeing Jon from his Night's Watch vow to "wear no crowns".

So despite Tormund's words, Jon may well become a king – in fact, unless Littlefinger manages to wrest Winterfell from Jon and become Warden of the North, Jon may well be crowned King in the North as early as next episode...
