Qhono is among the Dothraki horde escorting a captive Daenerys Targaryen along with Akho, leading her to their master Khal Moro. Along the way, the two Dothraki taunt and mock their prisoner. Later, he is present along with twobloodriders plus Moro'swives as the Khal contemplates raping Daenerys prior to her revealing her true identity as Khal Drogo's widow.
During the Khalar vezhven determining their charge's fate, Qhono was in the city during the talks when the temple was set ablaze by Daenerys, killing his khal plus nine others in addition to the other bloodriders. He watched on in horror as the wood-and-thatch building burned to the ground, knowing he couldn't do anything about it. After he saw Daenerys emerge completely unscathed, Qhono joined the rest of Vaes Dothrak's denizens in bowing down to their new Khaleesi.
In the books
In the A Song of Ice and Fire novels, no Dothraki named "Qhono" has been mentioned in the storyline as of the fifth novel, A Dance with Dragons. However, the storyline in which Qhono is involved in the show will not appear in the books until the sixth book in the series, The Winds of Winter, which has not been released yet, so he could appear in that book.
