Ben cried when he told everything to his mother. From the start of his meeting with Gaile, until the first time, the figure of a man who looks like Alex is seen. Not to mention the reason Sarah followed him to the hotel was that Sarah panicked to hear him cry when he called Sarah. Until the incident earlier, the incident triggered the fight between him and Sarah, which caused them both to be silent.
"Are you sure it's Alex, Sarah's dead ex-husband?" asked the mother while wiping her beloved child's tears.
"I don't know, Mom. I'm not sure it was him either. How can someone who died almost seven years ago come back to life, and when he greeted me earlier, he didn't seem to know who I was, Mama? I wish I was wrong. He's someone else. I don't want Sarah to leave me, Mom. I'm scared!"
Ben is honest with all his assumptions that are still not proven. He hopes that what he sees is wrong and that Ben's wishes come true, that the man Gaile's husband is not Alex.
