Lucille wasn't herself so she wasn't able to stop herself from going against the witch queen, their first plan would commence today and she was to execute it, failure to do it would make her incur the wrath of the queen and mostly her aunt, Tess.
Lucille stood on the castle's roof in a black cloak, she awaited Karen who just entered the conference room, according to the witch queen she should have cast a spell him before he went in. They would be able to control his mind and body once she cast a spell on him, if she had done that earlier Karen would have caused confusion in the conference room which would make the rest of their plan easier.
