Two: someone has my wand, in which case I'm probably not in a state to care about someone coming in. Three: someone has a key that was touched by my wand. There's only two and my mum has the other one. If anyone else touches it besides you, it changes shape and is worthless." Bastet was starting to fall asleep in her arms.

Of course, extremely powerful dark wizards or witches could break through her wards, but she was almost certain none with that power were left alive. "I trust you, though." She kissed him on the cheek again, lingering this time before pulling back.
