It was risky to move without company at this critical time however Natalie still slipped out, cautious as ever. She had to meet Ruth and as much as the guards wouldn't spill her conversation, she still couldn't trust them considering they answer to her husband, Eric. He can't know what she did. What if he comes to hate her because of her actions? She can't let that happen.
Hence she lost them on purpose but unlike before, she knew Eric was going to begin to suspect her. Yes, she was entitled to her privacy but the period was dangerous and those men were for her safety. He knew her well enough to know that she was hiding a secret. Natalie was hoping that he would turn a blind eye like he did in the past.
She packed her car and stepped out, already spotting Ruth waiting outside her car. The parking lot was silent with no one around but Natalie had no doubt Ruth's men were around the corner to keep her protected. She never moves alone.
