So .... the socks off, hmmm ... What bout if we wear no socks ...
For the Plot: Yeah Dad is still Alive and will fuck us again.
Its easy to believe that the father would be alive.
However I doubt he would come back just to fuck you over.
There was too much done to keep it still within the lines of reason. (even though somethings are out of reason)
Very often will's have stipulations in them.
Not trusting people with money and giving it to them as a stipend as one example.
I think the fucking you over, is going one step too far into bad/lazy writing.
From how it comes across, he wants to screw over the M.C. but he really wants him to become stronger mentally and
not reliant on people. However with that being said. The stipulations are more a sign of distrust in his son being able to walk away and be who he wants him to be.
The father is controlling yes.
But its shown that he wants his son to be strong or at least mirror what he see's as strength.
He's getting his wish of everyone playing a game he intended them to lose.
We know he would like his son to get it all but we know from the reading of the will....
He thinks very little of his son.
Saying him screwing you over once again as a the last part of the plot, I think is not giving enough credit in writing,
as well as aiming for low hanging fruit.
If there is going to be more coming from the father it will be something unique most likely.
