Karyn ran after him as fast as she could. She wanted to be within the "safety radius" when he used the device. She didn't want to forget this reality.
As she ran, she noticed the front door of the McMillan house opening.
"Jon, wait!" Karyn yelled. "Wait for me!"
This time, Jon responded to her and stopped in his tracks, giving Karyn time to catch up. When she met up with him, they watched as someone emerged from the house. And without thinking, Jon fired off the device.
