It's time to overanalyze! We just love doing that here on the forums LOL
HBO just released the new posters for Season 6, or should I say, poster (singular). Since all we really care about is the one character, Jon Snow. I really don't think they need to release any other poster to advertise for the show.
In case you didn't read the title, too bad. Jon Snow died/passed out in the S5 finale after being stabbed multiple times by his fellow Night's Watch brothers. As a complete A Song of Ice and Fire nerd, I read this scene back in 2012 and have been trying to figure out ways he isn't actually dead and/or comes back ever since.
I can't figure out anything from this poster and it's killing me! Is he "alive" in this poster, or is he a corpse? The only color is the Stark red of the blood (pun intended). Are they giving us a false since of hope, since we know they like to fuck with us fans?
I see this going the following ways:
Jon Snow is dead dead and will only be in flashbacks and/or visions.
John Snow will come back as an Other (that's why he's all blue/gray) and have pretty blue eyes now.
John Snow has warged into his direwolf Ghost and Melisandre will resurrect him somehow using her powers with the Lord of Light. Probably from fire when the Night's Watch burns his body so he doesn't turn into a Wight.
All I know is that they can't kill him until I find out for certain that his parents are Lyanna Stark and Rhaegar Targaryen.
I guess in the long run it doesn't matter, since no matter what I'll be tuning in to watch the show next April.
