When they reached the meeting spot, their twins also arrived. Jon-A and Karyn-A saw that their twins hadn't done exactly the same thing as them. In fact, they looked exactly the same as when they left.
"You didn't experiment with the stone?" Karyn-A asked.
Jon-B and Karyn-B just stood there and didn't speak.
"Are you two okay?" Jon-A asked.
Their twins stood still, not making any movements.
"This is weird," Jon-A whispered to Karyn-A. "What's wrong with them? It's like they're zombies or something."
Karyn-A agreed. It was eerie, to say the least.
Then, suddenly, their twins began to hum. It wasn't a song, but just one continuous note.
"What are they doing?" Karyn-A asked.
But Jon couldn't answer. He had no idea.
