Now a prisoner of the khalasar, Daenerys is brought before their leader, Khal Moro, enduring remarks about her appearance from her captors. Out of jealousy, Moro's wives suggest killing Daenerys, though he repeatedly ignores them. Daenerys reveals her identity, but Moro laughs off her titles, saying she is nothing more than his bed slave. Daenerys refuses, revealing herself as the widow of Khal Drogo. As it is forbidden for a khal to sleep with a widowed khaleesi, Moro has a change of heart, cuts her free and promises no one will touch her. A grateful Daenerys promises to reward him with more horses if she is returned to Meereen, but Moro informs her that she will be escorted to the Temple of the Dosh Khaleen in Vaes Dothrak, a home for other widowed khaleesi.
Daenerys is polite and well-spoken, but filled with quiet determination. She used to be cowed by her brother's ambitions and his occasional cruel rages, but her time amongst the Dothraki has taught her pride, confidence and skills of command. She is still somewhat naive of the world due to being young and living her life as an exile (with only her petulant brother to rely on for knowledge), but she is intelligent and quick to understand now that she is free to pursue her own path.
Daenerys spent her entire life living on the sufferance of others, bouncing back and forth between one benefactor or the next (like Illyrio Mopatis) with her brother, until whatever dreams they had of supporting the exiles' claim wore off and they'd have to move on to another patron. As a result, Daenerys has never known a true home. Constantly living under her brother's domination has given Daenerys a great empathy with the downtrodden of the world. She is deeply sympathetic to those she perceives as oppressed, while at the same time, her pent-up frustration from years of being mentally and physically dominated by her petty would-be-king of a brother make Daenerys capable of being utterly ruthless against those she perceives as oppressing others. This has produced a large amount of black-white thinking in Daenerys's mind, and she can be idealistic to a fault. For example, on seeing the plight of the slaves in Slaver's Bay, Daenerys becomes determined that she must free all of the slaves in the region - with little thought devoted to the practical after-effects which will result from this. A particular example is when the Great Masters of Meereen crucified 163 children as she approached the city, in an attempt to intimidate her. After she took the city, instead of pardoning the slave-masters, she had 163 of them crucified in retribution, unconcerned about any negative political fallout which would result.
Unlike many in her House, Daenerys has thus far not exhibited the "Targaryen madness" that plagued her father (and to a lesser extent, Viserys). She can be ruthless to her perceived enemies, but while Viserys was cruel and demanding to his servants and even his benefactors, Daenerys reciprocates the loyalty of those who follow her with gratitude and compassion. On the other hand, insanity was often a late-onset condition in the Targaryens, and it remains to be seen how Daenerys's mentality develops as she matures.
Some viewers have the misconception that Daenerys is "fireproof", given that she hatched her three dragon eggs in Drogo's funeral pyre. Martin, however, has stated that this was a special circumstance, a blood magic ritual involving "fire and blood" - only life can pay for a life, so burning Mirri Maz Duur in the funeral pyre was enough to awaken the life in the dormant dragon eggs. Under normal circumstances, Daenerys is no more immune to fire than any other human. Her brother Viserys once claimed in the novels that Targaryens were a race above other men, immune to both fire and illness - this was blatantly wrong, given that multiple Targaryens in the past are well-known for having burned to death, and many have succumbed to common illnesses over the years (including Greyscale). Viserys's comment just highlights how little he knew about Targaryen history (or anything else). Targaryens do seem to have a slightly higher heat tolerance than average: at Illyrio's mansion Daenerys takes a bath in near-scalding hot water, despite the protests of her maidservant, but in the novels she thinks to herself how pleasant the heat feels (this also happened in the first episode of the TV series). Still, this is nothing outside the normal human range - i.e. any more than centuries of history have shaped the Dornish to be more tolerant of dry desert heat, or shaped the wildlings to be more accustomed to a cold climate. In fact, when Daenerys rides Drogon out of the Great Pit of Meereen, she is stated to have burns and blisters on her hands from the flames
