Maid's Background
The maid looked at Sam with hesitation. She is very reluctant to give it to Sam, but the threat of the woman was very much real. She knows what that woman can do and what is at stake, which made her feel a bit determined.
But when she saw Sam, she remembered that he not only gave her this job without much demands, when they first met, he clearly pitied her and showed some kindness. He was never excessive. He knew that she had a problem and asked her indirectly, prompting her to say it out loud.
But she is afraid that Sam will back down. But that is not the only reason she did so. She knows her problem is excessive, but if Sam fails, she wouldn't be able to live with herself considering what is at stake here.
