Let me try to rephrase myself.
Ok, this isn't in order but it might correct a lot. You can specify, if you want, a female for her mother. It just isn't something on our canon list. Perhaps it was someone who didn't marry her father. When we developed the canon list, we did not fill in all the gaps because if we did, that would have taken away from some of the members' ability to be a bit creative--within reason, of course.
So, yeah. In this case, you either need to specify that she has a mother or how it is that she doesn't know. Perhaps that her father had several girlfriends and came home to find the baby at his place leaving it up to him to take care of.
Just because that's the OOC framework that you have, doesn't mean you can leave it not making sense IC.
Same with the arranged marriages. You're missing my point. My point was where is the negativity coming from for her with arranged marriages? It isn't something that normally is an issue in England. Why is it a thing for her? Most people in England presume they will have the right to choose their partner. Why is it an issue in her thinking at all?
A child being spoiled doesn't automatically tell me that she has a strong desire to please her father. When I think of a spoiled child, I think of someone very self centered who often doesn't think of others.
The brother is a bit of an undeveloped issue. I don't see it specified how much older he is, and it seems to conflict a bit--that they get along at times and that sometimes he resents the attention she gets. Since he is a Slytherin, how does he really treat her? Unfortunately, their father's heritage is no guide for you since he came from Durmstrang.
My request was that you develop the character more on the app, Cec. I want to see more development of the character in the app itself.
