Aoi gasped as she saw the change come over him. She started to reach out to him, when he moved at his fast speed.  "Rex..." She managed before he was out the door. She saw what had happened, she would  bury that in her heart and she vowed to find a cure. "Rex, I will find a way to save you." She whispered to his disappearing back. She walked out the door, the rain washing away the tears she felt, knowing that she would have to do something drastic to save him but she would do it none the less.
