"I've always been hearing this and that Spirit but I've never fully understood them. What are they anyway? Are they like dead people... but they are giving me powers so I don't know..."
Trisha has always ignored this topic since it reminds her of the trauma she had when she was a child. The time when she learned that her suffering lessened only becuase it was passed onto other people, building their family's wealth on it.
Because of her, her family has become sinners.
This has been bugging her since she's a child so to stop this, she would act strong and be strong. She learned that being strong would make her handle her suffering and that she will only keep it for herself and her alone.
Now, though, she felt fine talking about it. Is it because she finally has the real courage to face it? Or is it becuase she matured? Or is it because she's talking to the person who she knew she can share her suffering?
