Game of Thrones Season 6 Teaser-OMG

Woah… HBO has decided to really mess with our heads in the new Game of Thrones season 6 Teaser.
There are some surprising inclusions in the Hall of Faces, and  in all seriousness, it’s got me feeling pretty nervous for some, if not all of my favorite characters. We’re not only given a glimpse of dead GoT characters honored in the Hall of Faces, but Tyrion, Sansa, Daenerys…  It’s hard not to assume the worst. Hopefully HBO is just messing with us, and this is just a bit of metaphorical misdirection. Jon Snow voice can be heard to warn “The long night is coming, and the dead come with it.”  What could this mean for our heroes and heroines?  Why must we wait until April 24 for Game of Thrones to return?
