Fiery Death Eater

As the Battle of Hogwarts drew to a close with the final combatants duking it out in the Great Hall, a person was seen flying through the air and their body was on fire. It couldn't be seen if it was a man or woman or if that person was fighting for Hogwarts or for Voldemort. He/she can be seen at the top right of the screen after Neville Longbottom recovers from Voldemort's attack. It isn't found out who the unfortunate person combatant is but chances are they died from the fire.

Behind the Scenes
This person is most likely a Death Eater seeing as how they lost the battle around the time this happened.
