12 Game Of Thrones Spoilers You'll Know Before The Books

5. Jon Snow's Patronage

Easily one of the most profoundly popular narrative threads in Westeros, the true nature of Jon Snow's lineage simply has to be dealt with before the books end. The way it has been hinted at throughout suggests that the plan has always for it to play a major part in the story's resolution. With the final book unlikely to come out this decade, it can only be a matter of time before the show reveals Ned Stark's big secret first. The Theory The most compelling theory is that Snow is in fact both a Stark and a Targaryn, rather than Eddard's bastard, having been born to his sister Lyanna after her relationship with Prince Rhaegar Targaryen. Having flirted with leaving the Night's Watch (and then been stabbed by his men), seeing him leave his oath behind him and claiming his birth-right (either Winterfell or the Iron Throne) seems inevitable.
