She asked, not sure Zoe would know any more. It was more a rhetorical question.
Zoe shrugged. He'd been the one interested in the occult. "I guess I didn't think out my wish...If everyone alive is now the other gender...the changes stretch back decades...It's what they call the domino effect. A guy fifty years ago was born a girl...so he wasn't somewhere he would have been as a guy..and became a ballerina instead of a stock broker...and suddenly lived a very different life...And that changed other lives...and suddenly...etc. etc....What the hell...You're a kid, I'm an adult, you know is it possible that in this reality I'm your dad?."
"no way! that can't be You can't be my Dad I can't be your little daughter that's too weird, even if it makes sense why we're here together, oh please don't be true"
"I agree There's no way I'm being a parent to some little brat."
"hey!" said the little girl angrily.
