Ella didn't take notes. Not because all of this wasn't interesting but because she wasn't sure she'd be using this information again. Also, she was sure Sophie knew a lot of this information because of her internship. She'd just casually poke her if she had questions. Best friend perks and all.

As for the wand cores, Ella raised her eyebrow and eyed the list curiously. Her wand core wasn't on there which was different. Mostly because she got her wand at Ollivanders.

"Sir? I noticed that Mackled Malaclaw shell isn't listed under cores. Is that because it is no longer used or because it is rarely used?" She was just curious, it being her core and all.
