"People!" Daniel shouted. He then jumped away from the wall he broke just a few moments ago, only to kill his momentum, turn around and get into a fighting stance.

"No, not enemies," Mathew said and shook his head before approaching the hole in the wall. "Nadia?" he then called out into the emptiness of the vertical tunnel that he didn't know existed just a few moments ago.

"Matty?!" a familiar female voice came from the depths of the tunnel. It was then followed by a set of extremely strange sounds. It was as if someone threw a cat into a metal pipe while playing percussion at the other end of it.

The noise got louder and louder. In reaction, the older of the policemen lowered his center of weight and brought his fist higher and closer to his face.

"Arty!" Mia shouted right as she reached the opening. She placed her foot on the floor and then used it as a springboard to jump out and leap right into Mathew's arms.
