‘Looking death in the eye’
A lot of the excitement from the teaser trailer comes at the moment when ice begins to spread its way through the crypt as Jon, Arya and Sansa gaze upon statues of their own faces.
“There’s clearly a lot there about having to look death in the eye and face it head on,” TV writer and Game of Thrones superfan Chris Mandle tells Radio 1 Newsbeat.
“We saw in the season seven finale that the wall has been breached.
“The white walkers are on their way, so it’s clear that they’re going to have to pull together and crack on basically.”
Both Chris and George think the Night King will be killed and his white walkers will be defeated – which is surely a good thing for Jon Snow and his family, right?
George doesn’t think so.
“I’ve got thousands of theories. They’re all probably awful,” he says.
“My theory is that Jon will insert dragon glass into himself and he’ll become the new Night King.
“He will in fact be the king in the north – but not the one that we wanted.”
Chris thinks season eight will end less controversially.
“Part of me feels like what we can expect is the invasion is going to take up the first half of the season will see them taking on the white walkers, and whoever survives that will then have to go south and deal with Cersei.
“I think she’s actually the big villain in all of this.”
