Having her wand in her possession would've given her the chance to blast the smug smirk off of the horrible man's face. In the chaos of her attack in Hogsmeade and then William Wood's attempt to kill her and every other horrible thing that had happened, she hadn't stopped to consider the fact that with their Secret-Keeper dead, the Fidelius Charm her husband cast on the cottage was no longer valid. Yes, it should have been a thought that she considered, but she had to remind herself that she was only human and unable to anticipate everything. Antonin was very likely even smarter than she was. Certainly he had more experience than she did and even he didn't seem to remember that their safe house would be left exposed. Of course, very few people in the world even knew it existed in the first place and her husband was operating under the assumption that his little brother wouldn't return any time soon. And she did suffer a concussion that horrible day Hannah was murdered. Maybe she was losing her mind.
