Jhiqui, Irri, and Doreah tend to Daenerys in her tent. Jhiqui doesn't say much, and comes across as silent and obedient. However she does side with Irri in saying that the moon is a goddess, and not a giant dragon egg as Doreah claims.
Jhiqui has only appeared in a single episode. It is not clear if she remained loyal to Daenerys following the death of Drogo, though if she did it is unlikely she survived long as Daenery's entire remaining khalasar is shown on camera in "Garden of Bones" and she is not present.
In the books, Jhiqui is frequently seen with Irri, both in service to Daenerys. In the TV series, however, she appears only briefly in one scene. Thus, it is unclear of the TV version of Jhiqui remains in Daenerys' khalassar or was among those who abandoned her after Drogo's death. The TV series condensed most of her role with that of Irri.
