Every SPOILER we know for Game of Thrones season 8

A lot of cast members gathered near the Dragonpit for a mysterious, protracted shoot

In the season 7 finale, over a dozen Game of Thrones characters met in the Dragonpit of King’s Landing to discuss the White Walker threat. Filmed at the Roman ruins of Italica near Seville, Spain, the Dragonpit scene featured the largest gathering of characters in years, and it looks like history may repeat itself.

That’s the crew turning the ruins into the Dragonpit, once again. What’s more, a lot of cast members were spotted in Seville around this time, including: Kit Harington (Jon Snow), Isaac Hempstead Wright (Bran Stark), Sophie Turner (Sansa Stark), Maisie Williams (Arya Stark), Liam Cunningham (Davos Seaworth), Conleth Hill (Varys), Jacob Anderson (Grey Worm), Gemma Whelan (Yara Greyjoy), John Bradley (Samwell Tarly), Lena Headey (Cersei Lannister), Peter Dinklage (Tyrion Lannister), Nicolaj Coster-Waldau (Jaime Lannister), Gwendoline Christie (Brienne of Tarth), Joe Dempsie (Gendry), Vladimir Furdik (the Night King), Lino Facioli (Robin Arryn), Tom Wlaschiha (Jaqen H’ghar), and Faye Marsay (the Waif), along with showrunners Dan Weiss and David Benioff. There were also Unsullied extras spotted on set. Clearly, something big was going down.

It’s hard to be sure what, though, which might be by design. We suspect that some of those actors were there as plants, with Wlaschiha and Marsay in particular standing out like sore thumbs. We seriously doubt Jaqen H’ghar and the Waif are going to show up in King’s Landing. HBO may be trying to throw us off here.

But what are they trying to hide? Well, we have one more SPOILER for you, but be warned: this is a big one.
