"What can we do?" asked Jon. "Get a hot cup of oil? See a movie by directly feeding data into our heads?"
"I don't know," said Karyn. "Wait a minute. Of course. I'm programmed with a map of the city. So I know that right around the corner we can go to ..."
"Wait a minute, Karyn."
"What?"
"I'm not as enthusiastic about touring this city as you are. All I really want is to be human again. Better now than later."
"Well, if you want."
"Yes. It's what I want."
"Okay, then." Karyn held the stone in her metal hand and said "I wish for me and Jon to travel through time back to the time when we originally left."
The city dropped down all around them, first becoming low-rise buildings, and then becoming small two to three story buildings, and then becoming houses. They were back in their neighborhood again. So, in a couple hundred years, their hometown would become that futuristic city.
"We're back!" yelled Jon, with joy.
Then there was a scream coming from across the street. It was a woman and she was staring at them!
Karyn looked down at herself and then at Jon. She was still a robot! And so was Jon!
"What happened?" asked Jon. "We left the city. We should be human again."
"Maybe the stone thinks we're still in the city."
"Why would it do that?"
"Well, technically, we still are in the city. Just an early version of it. Remember that in the future, this whole area will become that city."
"So ... we need to go outside the city limits?"
"It seems so."
In the distance, they heard sirens. And when they looked in that direction, they saw police cars, quite a few of them.
"We better get out of here, Jon."
And they raced away from the police towards the outskirts of town.
