For all the build-up about the Essos band of sell-swords joining Cersei's cause, the army actually has remarkably little impact during Daenerys's siege of King's Landing. Like, so little impact that Dany and Drogon blow them all to smithereens in a matter of seconds, and the stragglers are picked off by the Unsullied and Dothraki forces charging into the gates immediately after. There isn't some grand, near-death fight between Harry Strickland and Jon Snow, or even a little hand-to-hand combat between him and a vengeful Greyworm. It seems strange that the show wasted time on them at all at the beginning of the season, though I guess I'm still grateful for all those elephant memes.
