Lorraine happiness is a bit shadow by the badass gramps getting rid of Viese at the end, though both are connected, as the straw that broke the camel's back was trying to almost literally sell Lorraine as profit, just as gramps said.
He takes care of his family, hence, why Viese is ruled out... He didn't care for her own child, he was going to sell her regardless her feelings and knowing she would never be happy just to make profit for himself. Gramps won't let anyone take profit of his family, ANYONE, even his own children. Fuck you, Viese, your little girl was shattered in pain about the marriage with trash first price and you couldn't care less.
Gramps protects his family, even from his own family.
Go away for good, Viese...
