Ep 4 season 2, really.. huge army turning point, and you send 1 dragon.... easily sent 3 or 4 and cleaned the land in under 20 minutes, then maelys and princess are much faster and mobile and could easily ascend faster and more be more agile from above and circle hagar and burn the wings and rider, and hagar falling on one hind leg like that from that height and own weight would snap legs... poorly executed, especially from a seasoned combatant dragon rider....
