Dumbledore taught her a mixture of meditation that felt ridiculous and ancient incantations that she'd never heard before. Everything about cloaking her magic felt weird and unnatural. She hated every second. More than a few times she was tempted to simply give it all up. Only her stubborn nature kept her from throwing the unregistered and supposedly "untraceable" wand in the wizard's face. Well, that and the fact that he'd had to Side-Along Apparate her to the middle of nowhere to complete their training. She wasn't even sure she knew where she was. Practicing where a member of the Resistance might stumble upon them was not a good option. Nor was the very real fear that she would mess up and use the magic she wasn't supposed to. Antonin or one of the other loyal Death Eaters would come rushing to their location. If she was found anywhere near the Resistance stronghold, all hope that she could become an effective spy would be dashed.
