Game of Thrones Season 7 was chock full of battle sequences that the show had been building to for many years, ranging from the loot train massacre when Dany unleashed her dragons on Westeros to Jon and Co.'s desperate fight against the wights north of the Wall. One battle came as something of a surprise. The siege at Casterly Rock in which the Unsullied were duped by Lannister forces came to a definitive conclusion, but one Game of Thrones star revealed to CinemaBlend how that particular conflict changed how the Unsullied fight now that winter has come. Jacob Anderson plays Unsullied leader Grey Worm, and he had this to say:
Jacob Anderson spoke with CinemaBlend ahead of the Blu-ray and DVD release of the complete seventh season of Game of Thrones, which will be available at the HBO Shop and retailers everywhere starting on December 12. As Grey Worm, Anderson was part of one of the most unexpected battles of the entire seventh season. Viewers had become accustomed to seeing the Unsullied destroying their opponents, and Dany's defeat had been difficult to imagine so long as she had the Unsullied on her side. In the Casterly Rock conflict, Grey Worm and the Unsullied expected to face thousands and thousands of Lannister soldiers. Instead, they found themselves challenged by a meager number of fighters, as Casterly Rock had been used as a distraction by Jamie, who instead led the bulk of the Lannister forces into the Reach to take out Highgarden.
Euron Greyjoy had a part to play as well, sailing his fleet into the bay outside of Casterly Rock and burning what remained of Dany's fleet, more or less stranding the Unsullied at a stronghold that they couldn't possible hold. Fierce as the Unsullied are, they were simply not prepared for the ways of fighting and strategizing in Westeros, and they paid the price. The good news for Grey Worm (and Dany) as the Great War approaches from the North and Cersei prepares for a sneak attack from the south is that the Unsullied just needed a "readjustment period" after Casterly Rock to recover.
Jacob Anderson went on to tell me how Grey Worm and the other Unsullied will have needed to change after the siege of Casterly Rock:
The years of intense training that prepared the Unsullied for all the fighting that Essos had to offer was not enough for what they were to face in Westeros. Their skills are still almost certainly unparalleled in the world of Game of Thrones, but they can't just rely on those skills in Westeros. Thinking on their feet could help avoid any other crushing defeats in what remains of the series. The stakes have never been higher than now that everybody on Team Dany will be facing enemies on two fronts, and she'll need the Unsullied at their best. Something tells me Grey Worm won't allow himself or the other Unsullied to be as shocked as they were at Casterly Rock ever again. Then again, they are facing a horde of ice zombies... we'll have to wait and see.
