What happens next?

Flame war

The dragon's attack was hardly the first time Buffy felt the impact of a dragon's flame upon her body but it was the first time that she experienced it without her magic potion. And yet Amelia's spell worked. To Buffy's surprise, her transformation into a dragon really did make her fireproof and once Buffy opened her eyes and realized that she was still alive, she felt a lot more optimistic about her chances against the dragon.

She started humming an odd tune she had heard earlier -- some strange little ditty that began with a wolf's howl and a few notes from a church organ -- and then realized something else. She had wings! Amelia had given her wings!

She could fly around the dragon now.

The dragon started to roar again and this time its roar was accompanied by some strange foreign music Buffy had never heard before. A real ominous tune that seemed like something one would hear from a foreign army on Judgment Day.

Buffy started to use her wings to rise up off the ground, only to hear a voice cry out, "Dragons are so stupid!"

As Buffy watched in horror, some short little knight with a red mustache started waving his sword in the dragon's direction, only to immediately perish when the dragon turned and gifted him with the same type of flame he had previously bestowed upon Buffy.

I need to end this because someone else gets hurt, Buffy thought.

Buffy started to fly up to the dragon's face so that she could attack. But before she could get there, she was swatted out of the sky by a sudden swish of the dragon's tail.

Next thing Buffy knew, she was landing in a nearby forest where she hit the ground with an impact that was not at all pleasant. Then she lost consciousness.
