Rose didn't realize the issue till they were back safe and sound. Yes, why did that person help her? She didn't know them. That was puzzling. Why would she use her ID to get them in?
"You got the info and you need the charms, right? Do you have them?"
Rose had charms. She had made those when she was in the human world. Now she could use them.
If she still had magic, she would have made a paper plane that would take and charm and drop it at the location. No need to leave the house. But now, she could use her magic sparingly. Spells like those became a luxury for her.
Madam Denise stayed with Rose for two days before she had to go back. It was inevitable. Till they could get the entire equipment and crew ready, she couldn't come back.
Rose felt like the sky was turning gloomy. It was something she felt deeper in her soul. Like something was changing slowly.
