They turned down the narrow walkway shaped like an archway covered in green moss that seemed to move and wiggle itself into cracks as they passed. Theo reached out and pried some of the moss from the old bricks adorning the left side of the alley. He pulled a small vial from the back pocket of his shorts and stuffed the moss inside as it fought to get back out. He shoved the vial into his pocket again and carried on as if nothing strange had occurred.
