One of the biggest 'House of the Dragon' book changes may have introduced a major plot hole to the show

HBO

• Addam of Hull becomes the dragon Seasmoke's new rider in "House of the Dragon" season two.
• This shouldn't be possible because last we heard, Seasmoke's rider Laenor Velaryon is alive.
• Laenor faked his death in season one in a major departure from the books.

Warning: Spoilers ahead for "House of the Dragon" season two, episode six.

"House of the Dragon" hasn't been shy about taking some liberties with its source material. But one of those changes has led to major confusion among some fans.
