Penelope wasn't sure if there was a way to break down the news that one was a witch and not a human as she knew how skittish the butler was. She could only hope that the butler wouldn't go running to the hills or worse to the mansion while screaming 'Witch! Witch!' at the top of his lungs.
No problem though, said Penny in her mind. If he were to do it, the worse case she would have to tie him up here to push him in the other empty cell.
"I am not a human, Durik," Penny broke the news to him.
The butler who heard this wondered if the lady was telling that she was not human enough but a monster. Maybe she was emotionally feeling cold?
Penny, on the other hand, gauged the man's reaction to seeing if the information had sunk into his mind to realize it hadn't, "I am white witch," she finally said without beating around the bush and his eyes went wide.
