"Use your stone to protect yourself from any magical attacks. Because I'm sure your sister's friend will likely try to do anything to keep my stone," Santa said. "She's generally a good person, her heart is in the right place, but she's dabbling in things she shouldn't be and if she doesn't stop ... well, let's just say, she could be traveling down a dark path and wouldn't know it until it was too late."
"Okay. But how do I protect myself with the stone?" Jon asked.
Santa sighed. "Make a wish."
"Oh, right," Jon said. "Uh ... I wish that I won't be affected by any magic that Athena uses on me." The stone glowed, granting his wish. Now, he could go to Zoe's bedroom and retrieve Santa's stone.
