In Game of Thrones, Daenerys has managed to survive fire or extreme heat in several instances:
When Daenerys' dragons were born in the season 1 finale, "Fire and Blood" (Game of Thrones, S01E10)
Killing the khals by locking them inside the temple of Vaes Dothrak and lighting the place on fire in "Book of the Stranger" (Game of Thrones, S06E04) - while all the men burned alive, Daenerys emerged from the hut unscratched.
The steaming hot bath in "Winter is Coming" (Game of Thrones, S01E01) - Daenerys is warned by a servant that "it's too hot, my lady", but she steps in without flinching
Daenerys casually picks up the dragon eggs that were roasting on hot coals, in "A Golden Crown" (Game of Thrones, S01E06) - when the Dothraki handmaiden, Irri, rushes in and knocks them off her hands, Daenery's hands are unscathed, while Irri's now have burn marks
Here she didn't show immunity to heat, but made a relevant remark:
- Her comment, "He was no dragon. Fire cannot kill a dragon", at the time of Viserys' death in "A Golden Crown" (Game of Thrones, S01E06)
George R. R. Martin, author of the novel series that the show is adapting, has stated that the Targaryens are not immune to fire (at least in the books).
Were the above instances in which she is shown to be immune to fire (in the show) unique, or has she had this ability her whole life? If so, when and how did Daenerys acquire this ability?
