Theory on how he got the girl
Hear me out,
Since it is said that the Rich Girl won the case because of her family's money, and that the Blind Man was left with a settlement of 300k(?), while later in the protagonists finds out that there is more than 300 grand in the safe and it was close to 2 million (?)
My theory is that the Rich Girl actually felt guilty and tried to apologize to the Blind Man by going to his house without telling anyone in her family, She then tried to offer the Blind Man more money as compensation but the blind man felt insulted instead, and in a fit of rage she took the girl then and there.
