An important part of the journey of Daenerys, is the remnants of the khalasar of Khal Drogo. She leads them through the Red Wastes to Qarth, boards the frightened Dothraki onto ships and sails for Astapor. Following this however, the mentions of the Dothraki become few and far between, both in the novels and the TV show.
We know the fates of Irri and Doreah, but what of Jhiqui? I saw some Dothraki briefly in the TV show, guarding the tent of Daenerys, when meeting the Second Sons in 4.3 or 4.2?
So my question is, who and how many of Daenerys' old khalasar are left? Are they integrated into her court? Do they serve with the Unsullied?
