My prediction is that vic blows the dragonhorn and Barristans forces take this as their signal for retreat as they pull back the dragons swoop in and decimate the yunkai forces. I dont know how many of you have ever tried to train a dog but after years of frustrated efforts sometimes a tone of voice can suddenly bring out the best behaviour in them. I think the dragonhorn is something similar to a training whistle.I hope personally that Daenerys flys back to meereen on Drogons back when Drogon is summoned by the horn. Victarian determines friend from foe .Barristans army would be clearly in a defensive position infront of Meereen. If Barristan went to enough trouble to dress in Queensguard armor he would surely of given instructions to make banners for Daenerys Army, besides that the yunki army with men on stilts and sharp metal beaks would be a sign of a very different influence than a westerosi Queen and her knights. Everyones speculating why Tyrion is miserable. Why would he be anything but miserable at this point.
