I don’t think she is divorced. (Possibly widowed). I think something traumatic happened, death of child, death of parent, death of husband. (Language she uses suggests husband is alive). I think someone died and Bella blamed her husband (rightly or wrongly) and time has passed and she has forgiven him. That doesn’t explain locked room, or creepy ‘hanging‘ army boots though.
I’ve suggested before her kid could have been sent to a military academy because Of husband and then died in an accident. So uniform is the sons.
MC is helping though not in the healthiest way. Bella is ‘the Ice Queen’ and yet MC has been able to get her to take care of him when he was drunk and upset. She also despite herself has a romantic evening with him in her study. If MC is played as a somewhat decent person, he flirts with her, jokes with her but also helps her round the house.
MC is helping her open up, and for whatever reason this kid has reawakened her sexuality. She obviously has a massive trauma, but until the secret is revealed there isn’t much more MC could do,
Maya isn’t spineless. The only people in the world who she knows love her is Josy and Derek. The rest of her family have abandoned her. That in turn has made her desperate. Perhaps you could say she is easy to manipulate.
I don’t remember this shot, though perhaps it’s because I skipped through on my last play through to get it set up.
