Hmm

I think he left his mom and sister together (not that it means anything... his mother's useless). He paid for everything to help her and told her that if she need's anything to tell the maid. (I bet the maid is suppose to tell Ewon if there's a problem).

I get what your saying. When Fox couldn't even take of his sister I thought it was kind of fucked up because it wasn't her fault that they didn't know each other considering their parents never said anything about the other.
