Sam finally understood the situation unfolding before him.
At this moment, Sophie wasn't Sophie, but her sister Sophia, seemingly an entirely different personality. However, Sam had always believed that it was another real soul residing in the same body.
Sophie's method of breaking free from Angel's seemingly irresistible control was to summon her sister Sophia.
If Sam had to make sense of it, it was because Angel controlled Sophie, but couldn't extend her control to Sophia, allowing Sophia to ignore Angel's manipulative tactics.
But why use this method only now? Why hadn't she done this when she was licking Sam's feet?
Had she forgotten? Or had she just remembered she could do this? Or perhaps, did Sophia need to overcome some limitations to appear?
Sam wasn't sure, but now, the situation had taken a completely different turn.
