"Where did you get this from?" Athena DeVries asked her friend Zoe Merlin. In this new reality, Jon Merlin no longer existed, so no one (including his own Goth sister Zoe or his little brother Mikey or his mother Linda) remembered him. And since Jon didn't exist, the Merlin family didn't really know Ethel (formerly Karyn) all that much either.
Zoe turned and saw the small stone that Athena had in her hand. "I'm not sure." In a previous reality (where Jon existed), Zoe had found the stone sitting on Jon's bedroom floor and had taken it for herself, even though she didn't actually know that it was a wishing stone. Now, since Jon no longer existed, she couldn't quite remember where she got it from.
Athena looked closely at it. "You know, I think I've seen something like this before."
"Really? Where?" Zoe asked.
"That bitch Sarah McMillan. I saw her carrying around a stone that looked just like this one."
"Why would she be carrying around a stone?"
"I don't know. Why do you have a stone that looks exactly the same as hers?"
"I don't know."
They both looked at the stone, wondering where it could have come from and why Sarah had one just like it.
