"For centuries our families fought together, against their common enemy, despite their differences, together," says someone who sounds like Jon Snow (Kit Harington). "We need to do the same if we're going to survive. Because the enemy is real. It's always been real."
The trailer ends with an ominous message from Sansa (Sophie Turner) who says -- -- quoting dad Ned Stark -- "When the snow's fall and the white winds blow, the lone wolf dies, but the pack survives."
We'll take that to mean more death is coming when the show returns to HBO on July 16.
