She had originally gotten the phone in hopes that when her parents" memories completely recovered that she would have an easier time communicating with them. However, that process had not been smooth. It had taken years for her parents" memories to slowly return, the charm unweaving on its own slowly as time passed. She had hoped that she would be able to reverse it once the threat had been over, but it had just taken too long and the charm had taken up roots in her parents" brains. When they slowly began to recover enough memories to understand what had happened, they were furious with her and no amount of explaining that she was trying to protect them had made them feel any better about the situation. She understood the sense of violation that they felt, but it’d been so many years since the incident and they were still holding onto that. They were often nervous at the sheer mention of magic, so she avoided the subject and never used magic in front of them anymore.
