"Why is that?" Anna asked.
"I think it's because of your uncle James. I knew that someone is going on with him, but I decided to turn into a blind eye and not further investigate." Other than her master, the Coleman family is the only family who made her feel at home.
However, after learning all the things that James is planning, she is starting to remember the horrible place she used to call 'home'. Back in that horrible home, their goal was no to kill her but to experiment on her. Despite their real intention towards her, Mary still felt that they were trying to kill her. And James made her feel like that.
"Brother and I should have told you," Anna said this, but she knows that it's too late to regret the decision she and her brother made.
