House of the Dragon's director has teased huge changes ahead of the epic finale next week. This season has been filled with bloody battles, dragon-on-dragon showdowns, and, of course, extreme family drama. However, House of the Dragon director Nina Lopez-Corrado has said that some major changes should be expected as the season finale approaches — so viewers might want to brush up on their Fire & Blood lore beforehand. In an interview with Entertainment Weekly, Lopez-Corrado revealed that Episode 7 had deviated slightly from the book, though she didn't specify where those changes were. Of course, both book and show fans will be well aware of the looming battle brewing at Tumbleton.
