House of the Dragon season 2 will return to an important Game of Thrones location, and in doing so could create a Daenerys Targaryen plot hole. House of the Dragon begins around 200 years before Game of Thrones, meaning that, unlike many prequels, it doesn’t have to worry too much about impacting canon. Unless, of course, it does something major such as, say, reveal Aegon Targaryen conquered Westeros due to a dream about the White Walkers.

Prophecies and dragon dreams aside, though, House of the Dragon doesn’t impact too directly upon Game of Thrones. That could change in House of the Dragon season 2, however, as the prequel somewhat surprisingly looks set to return to the Wall. It’s not yet clear exactly why the Wall is in House of the Dragon, but there’s certainly logic to going there. At the same time, it could also lead to continuity issues surrounding Daenerys.

HOTD Season 2 Could Conflict With Daenerys’ Dragons Going Beyond The Wall In GOT

The Wall doesn’t feature in the parts of George R.R. Martin’s Fire & Blood that tell of the Dance of the Dragons, but there is one likely way for it to factor into House of the Dragon season 2. Following on from House of the Dragon season 1’s ending, Jacaerys Velaryon is flying to Winterfell - via the Vale - to meet with Lord Cregan Stark in the hope of winning his support.

It’s said that Jacaerys and Cregan became firm friends, and so it’s possible that part of their bonding will be a nice lads trip to the Wall on the back of Jace’s dragon, Vermax. The Wall is one of the wonders of Westeros, after all, so it’s not unreasonable Jace would want to see it while he has the chance, before his life is consumed by warfare. If Jacaerys does fly his dragon to the Wall, then it would also raise the question whether Vermax will fly beyond it.

This was not a problem for Daenerys’ dragons, who went over it without any hesitation to rescue Jon Snow et al, but that hasn’t always been the case in Game of Thrones history. Prior to Dany, the only notable example of a dragon going to the Wall was Queen Alysanne’s Silverwing (who will be among House of the Dragon season 2’s new dragons). Unlike Drogon, Rhaegal, and Viserion, Silverwing completely refused to fly beyond the Wall - or, as has been theorised, was prevented from doing so by its magic.

If Vermax goes across the Wall without a problem, then it essentially confirms Silverwing was a one-off, and likely just specifically spooked by the idea (understandably so). But if Vermax doesn’t, then it suggests a rule: that there is something innate in these dragons that warns them from going beyond the Wall (quite possibly linked to the existence of White Walkers; the ice to their fire and, so, their natural enemy in many ways), or old magic from the building of the Wall that somehow keeps them out. And if either of those are true, then Daenerys’ dragons really shouldn’t have been able to cross beyond the Wall either, which would then create a Game of Thrones plot hole.

The Wall Is Worth House Of The Dragon Season 2 Risking A Game Of Thrones Plot Hole

Despite not factoring into the book, and even with the risk of creating a Game of Thrones plot hole, going to the Wall is an exciting prospect for House of the Dragon season 2. That's true for Jacaerys' story, as further developing his and Cregan's relationship (or, based on some of the more salacious rumors from Fire & Blood, his relationship with Cregan's bastard half-sister, Sara Snow) could be great for fleshing out his character and adding some levity to the series.

Beyond that, there's also a more thematic connection to visiting the Wall, which could also tie into Vermax being there as well. House of the Dragon season 1 revealed Aegon's dream of the White Walkers, and his Song of Ice and Fire has in some ways defined the show's story, shaping Viserys and Rhaenyra's arcs and then Alicent's decisions with making her son King. Jace is Rhaenyra's heir as it stands, so would be the next to learn of the prophecy; him visiting the Wall, beyond which the White Walkers lived, could fittingly tie in with all of that.
