Karyn Wants to Try the Necklace

"Whoa," Jon said. "What is it this time?" Karyn asked. "I ... I remember Zoe. This is too weird." Memories of his previous Goth sister cascaded through his mind, changing his already-existing memories into new ones (or rather returning them to what they used to be before Zoe disappeared). "Now do you believe me?" Athena asked. "Let me try it," Karyn said. "Uh, I don't know. I don't think I should take it off until we get the stone back," Jon said. "Oh, come on. I'll give it right back. I just want to know what it's like."
