"Zoey?" Sarah muttered, her bottom lip trembling. "She — she knows?"
Sarah then turned her head towards Zachery. Her husband gazed down and at that moment, her heart sank. All this time, Sarah believed Zoey never had an idea. Zachery never told her.
That's why Sarah kept her act of not knowing Zoey's origin. She pretended to be that welcoming foster mother who loved Zoey, even though she's not her own.
But after that talk with Vivian, everything had changed.
"I always noticed Zoey's hostility towards Dad. Maybe, she's scared that you'd attempt to dispose of her again and she would fight back this time. Maybe… just maybe, if you did what you've done to her years ago, she's afraid she would end up taking the life of my father. Maybe, after all these years, Zoey knew you dreaded her presence, and she knew what you're capable of. But because of me and the innocent mother she assumed I had? Maybe because of that, she held back."
