1. a larger number of nuns are corrupt than you think especially ones in a position of power such as Mother Superior since power corruptsWhy are big nuns on the inside and an evil organization.
Why cant the MC just visit the fucking convent? He literally leaves the house and walks around the town seconds after getting home
Why does a nurse know random ass numbers means a safety deposit box
NOW why does she know the fucking purity level of gold bars
And now Sara is back and everything is back to normal. What was even the point.
2. likely trying to keep the fact he is alive a secret from as many people as possible may be the cause
3. that is actually a good question, she may have a Safe deposit box herself but that is still iffy
4. the purity and weight of gold bars is stamped on them, along with other information such as serial number, processing company, etc.
