Bella hadn't meant to catch him off guard. When she was walking in she wasn't even sure if there was anyone there. There wasn't anyone in the front. She had only assumed that meant it would be okay for her to go looking around for some assistance.
She took a small step back. She turned her head back towards the entrance. "I didn't see anyone in the front so I thought I would walk in," she said as she turned back to facing him.
