At the Game of Thrones panel at this year’s SXSW, showrunners D.B. Weiss and David Benioff said they’d love to do an episode of Adult Swim’s Rick and Morty once the HBO series concludes.

The response came from a question about what the pair’s plans are beyond the show. As a bit of a surprise, neither hesitated to respond in agreement about collaborating on the sleeper hit cartoon series co-created by Justin Roiland and Dan Harmon. There was, however, one big catch…

Die hard Game of Thrones fans will know that there have been several instances throughout the run where well-known musicians made subtle appearances. And at SXSW 2017 today, showrunners David Benioff and D.B. Weiss revealed that this season is no different.

While neither made mention of the exact episode or scene, it was confirmed on stage that musician and adult-Ron Weasley lookalike Ed Sheeran will be making his way to Essos.

We’re speeding toward the end of Game of Thrones (*sniffle*), and that’s something we just have to accept (knock it off, you promised yourself you wouldn’t cry). But while the end of the main series begins to come into view, anyone who has been paying attention knows that this is more than likely not the end of our time in Westeros and the surrounding areas.

For a while now we’ve been hearing about the potential for a spinoff series, which would focus on other stories set in other times. Those familiar with author George R.R. Martin‘s “A Song of Ice and Fire” world know there’s an incredible amount of history there, much of which would make for some great TV. HBO’s president of programming Casey Bloys talked about this recently, saying it would more likely be a prequel series than a spinoff. He also revealed that season eight of the current show, the final season, could end up being a little longer than previously believed.

See what he had to say below.

HBO has announced that they will release Season 6 of Game Of Thrones for on Digital HD on August 1, 2016, with the DVD and Blu-ray debut coming on November 15, 2016.

There hasn’t been a shortage of excitement for fans of Game of Thrones, as the past six seasons have been defined by its gripping story. Now that Season 6 is over, fans can look forward to Season 7. Showrunners David Benioff and D.B. Weiss have been pretty vocal about the future of the series, including how many episodes are left. Based on previous interviews, there will be a total of 13 episodes remaining to be divided between Seasons 7 and 8.

Now we have confirmation of a shorter episode order for Season 7 and when it will premiere. More on the story below.
