Everyone hovered over the monitor where Styles replayed Katherine's video from their phone call with Parker earlier. It was hard to look at because of her state, but they had to check it thoroughly to get more clues. The video played several times while Chris and Styles wore headphones to listen to it very carefully.
"Their voices…. It sounds echoey like they're underground," said Chris as he kept his stare at the screen. "Wait—stop. Rewind." Styles followed his command and stopped at the part where the camera pointed at the ground for a couple of seconds.
"That looks like a red line," Amelia observed. "Is that the training room?"
"You think so too, huh?" Chris probed.
Amelia and Styles agreed. Amelia and Chris spent a lot of time in the training room of the old Castle that even the floor became very familiar to them.
Seeing their confident looks, Styles chimed in, "Then this proves it. They're outside Cona."
