Jon Snow (Kit Harington)
Where we left off: Jon’s brief tenure as Lord Commander, with its unprecedented tolerance of wildlings, rubbed many members of the Night’s Watch the wrong way (et tu, Olly?). Season 5 ended with Jon bleeding out into the snow.
Quote: HBO left Jon Snow quoteless, possibly to spark wild speculation, and possibly because Jon Snow simply knows nothing worth quoting.
Chances he’ll return from the grave: High. Putting aside all the set sightings and fan theories about warging and Red Gods and Azor Ahai, Jon Snow has been such a huge part of HBO’s press machine for the upcoming season that it would be shocking if he didn’t turn up.
