House of the Dragon has already had one of its major twists spoiled… by none other than Game of Thrones. 

Be warned, we're about to delve into major book spoilers which might not play out on-screen for many seasons yet, but involve a key character from the new show. So, go no further if you want your House of the Dragon viewing experience to remain unspoiled.

Rhaenyra's son, who has yet to be born in the show, does indeed watch his mother's murder by Sunfyre, Aegon's dragon. (To make things more complicated, Rhaenyra's son is also called Aegon…) 

Of course, there's still a long way to go until the show reaches this point. Aegon the Second is just two years old at the moment. But,
