Season 7 SPOILERS: Family conflict, whither Jorah, and a fight in the chilly North

Time for a Game of Thrones Season 7 SPOILER roundup. Proceed with caution.

At the moment, the Game of Thrones production is hard at work filming on a private estate called Las Breñas, and will shortly begin a 22-day stint on the the Los Barruecos Natural Monument, where it’ll film a bit battle. Actors have been seen in nearby Cáceres.

It’s no surprise to see Nikolaj Coster-Waldau (Jaime Lannister) or James Faulkner (Randyll Tarly). The battle is expected to involve both a Lannister army and a Tyrell army led by loyal Tyrell bannerman Randall. Seeing Jacob Anderson (Grey Worm) is a bit surprising, though. We’ve heard that Daenerys will also be part of the battle, ambushing the Lannisters with her Dothraki forces as they leave Highgarden, but we didn’t know if Grey Worm and the Unsullied would be with her. We’ll keep an eye on that.

In other big SPOILERS, Watchers on the Wall has news about what’s going to go down at Winterfell in Season 7. As previous reports have suggested, Arya, Sansa, and Bran will all reunite. (It looks like Jon will be busy elsewhere for much of the year.) However, Watchers reveals that, after some initial euphoria, there will be some acrimony between the siblings, at least for a while. In particular, Arya and Sansa will clash, as their life experiences have turned them into very different people. Seeing this, Littlefinger will try to drive them even further apart. Should turn out well.

There’s also news on the Jorah front. Keen to carry out the orders Daenerys gave him in Season 6, he’ll reportedly travel to Oldtown where he’ll encounter Maester-in-training Samwell Tarly. Upon hearing that Jorah is the son of his former Lord Commander, Sam will assist Jorah in his quest to heal himself. We’ve seen Iain Glen (Jorah) and Emilia Clarke (Daenerys) filming together, so one assumes that they succeed.

Finally, Watchers reports big news about a set being built at Wolf Hall Quarry near Belfast.

That’s a green screen near a frozen lake with an island in it, blanketed in fake snow. Watchers has learned that the production will film at this location for three weeks, that filming starts next week, and that the sequence will involve 300 extras playing wights. Those tuned in to a Season 7 story leak that broke some time ago can probably make a good guess as to what may go down there. In any case, things promise to get intense.
