It was an amazing thing to watch her make ice which became snow from literally nothing visible to the eyes. Charlie had never seen anyone do what she could do. He'd seen a lot of things, too. There was no real surprise on his face so much as joy.
Who was he to question another person's miracle?
"That's amazing. You're really talented. I know what you mean though. About limits and powers. Even I have my limits. I wish I didn't, but, in another way? I'm glad. People deserve to pass on in life if they can."
Charlie wished he could summon a spirit more than anything. He'd call for Sam every day at the beginning of the day and have Sam with him until he went to bed at night. They'd never be apart. It would be the ultimate way to fulfill his promise to his brother for how he'd never leave him alone. No spirit really came when called though, not in Charlie's experience.
They lived -or, well, existed- by their own rules. No one could make them come or go. As long as they weren't malicious. He knew a priest could banish a malicious spirit and if anyone disturbed the bones of the deceased, that could influence how they came and went.
"Sara's laughing," Charlie said, waving to the ghost girl before she skipped off to wherever she was going to tell whoever it was she knew in the mall about the lady who made snow for her, "She raced off. I think she wants to brag about meeting you. I wouldn't blame her. What do you do at home? Do you build things out of the ice?"
