The Lannisters, who were extremely happy after defeating and looting the Tyrells, were returning to King’s Landing and that’s when they were stunned by a surprise attack by the Dothraki, lead by Daenerys on Drogon and it soon turned into a carnage with Drogon roasting alive Daenerys’ enemies and even destroying the wagons that were carrying the loot from Highgarden.
