12 Times Game of Thrones Sneakily Foreshadowed the Future

Impossibly old, wise, and thoughtful, Maester Aemon had a bit of a soft spot for Jon Snow right from the start. He defends Jon when Alliser Thorne wants to have Jon executed for "abandoning" the Night's Watch for the Wildlings and casts the last vote to make Jon the Lord Commander in season five.

While Aemon makes no claim or obvious suggestion that he thinks Jon might be more than just a bastard, he does give a very big (albeit inadvertent) hint in season five. He's talking with Sam about Daenerys, and remarks that "a Targaryen alone in the world is a terrible thing."

The camera cuts back to Sam listening, and then the door behind Sam opens and Jon walks in as Aemon's words still hang in the air. Sure, at the time it can really only be written off as coincidence — but at the end of the next season, it's revealed Jon is in fact a Targaryen.
