Usually in the Game of Thrones universe, no character is confirmed to be no longer alive until we see a body, and even then, there are still possibilities, as Jon Snow proved. But in Season 3 of House of the Dragon, it really seemed like one character — Aegon’s injured dragon Sunfyre — was gone for good. His body was supposedly decomposing, with an enterprising local charging for the opportunity to touch the creature.
But Aegon swore up and down that his dragon was still alive, even if Larys dismissed this as mere denial. But in the latest episode, we learned that Sunfyre lives — and thank goodness, because he plays an important role in Game of Thrones lore at large.
