Is there a cause to grant Lorraine's demand for money from the Roths?

None. David Rene is instructing her. Because David Rene wants to fuel his erred lineages who had been doing corruption since 2000.
It so happened they had known the sole past kid of the Construction god who was Woman.
So they tried to manipulate the flow and use Woman as captive for demands. In their own wants they had stolen the funds.
Now... the oil trade of Man was affected.
When they are not lineages of Man.
