In Knives Out (2019), why did Harlan leave his fortune to
Marta?
I get it might have something to do with wanting them to be responsible for themselves, not be dependent on Harlan, but it seems this only applies to Walt, Joni, and Ransom.
Linda had her own business (in something I forgot), so it seemed she had made something of herself. Sure, she had a million-dollar loan from Harlan, but she still had to build the business herself. So it seemed like she was worthy to receive something from Harlan. At the very least, the house.
