Damon didn't really think that this woman was a witch. First, magic was not real. Everyone knew that. It was a fact of life, even. Second, that woman was delusional, clearly, but she did not fit any picture of a witch that Damon knew. She was thin, attractive, with clear good looks. She had none of the characteristics of a witch that was what he knew - or thought he knew - about witches. Circe did not possess a warty hooked nose, wrinkles, disgusting moles, grey dishevelled hair and a hump. Her clothes were not ragged and filthy. Damon thus did not believe for a second that she could really wield magic, or that she possessed an ounce of any powers. But Damon had not read enough mythology and he was about to regret it. Nevertheless, he decided to at cocky. A bad idea but Damon, without being downright evil, had never been the sharpest tool in the shed.
"So you're a witch? Riiiiight..." he sneered. "In that case, turn me into a frog."
"A frog? Are you sure?" asked Circe.
That fool was mocking her but soon the last laugh would be hers.
"Yeah, if you're a witch, that's logical. Witches always turn people into frogs, right?"
"You know very little about witches," said Circe. "But if that is what you wish..."
She cast her wand at Damon and the young man felt himself surrounded by a big puff of smoke. When it cleared, all around him was gigantic. And he felt so small... And his hands... were tiny. Green. Slimy. He tied to scream but only a pitiful croak was hard. Oh no... The giant that Circe had become advanced towards him. She was terrifying, so big! He tried to hop away but she grabbed him by the foot before he could perform his first hop. Dangling pathetically, he could barely move.
"Good. Now that you are my cute little amphibian pet, let's get you settled you in your new home."
She walked away and after a short while placed Damon in a terrarium, leaving him after blowing him a kiss. Poor Damon was left with his new frog body, wondering what was going to happen to him...
