"Can you make wishes yourself, by touching yourself? I mean, you are human now," Jon said.
Karyn touched her arm. She seemed a little uncertain herself. If she could make wishes just by touching herself, it could be really bad for Jon and maybe everyone else. Sure, this Karyn had all the memories of the original Karyn, but Jon still didn't trust her. She was a magic entity - one that used to be in the form of a small stone just minutes earlier. She could have motives all her own, for all Jon knew.
"I wish my shirt was red," Karyn said, causing Jon to sigh a bit in relief. For a moment, he thought that she'd wish for something more daring and problematic, but her wish was just a simple test to see if she could make wishes herself.
