Jason found it hard to believe what he was told but he knew that this was a possibility because it all added up; if this was the case, why didn't Allison just come clean?
He wouldn't have known what was going on if Bella didn't reveal what she had discovered.
But if Mariam was the one responsible for everything that had occurred then he had more things to worry about.
Jason realized that this community was just as deceptive as any other because what is a woman who is willing to sacrifice her husband for the sake of leadership?
There were stories about how she didn't agree with her husband's method and this was why her lover was surprised when he heard that his wife had allowed new people to enter the community.
Now it made sense, she allowed them in because of Allison not because of what Carl had told her.
This was a cover, an act as this wasn't the first time her son was recommending someone.
