Father and Son sit silently, lost in their own thoughts.
Adam is wondering what Jack is thinking while Jack is thinking about what Adam requested from him.
The more Jack thinks about it, the more it makes sense.
Putting all his assets under Adam's name is the best possible thing he can do, and if the worst happens, he will not get exploited.
He knows his son his right, his wife is a manipulative bitch who knows how to make things work for her, and it almost worked.
Jack is not stupid enough to let himself be a victim of manipulation, and in his world, many are out for him.
In fact, he doesn't even fully believe his own son. He thinks that Adam has alternate motives behind his actions, but Adam is also the safest bet Jack has.
Their relationship might not be great, but it is bound by blood, and if anything were to happen to him, Jack wants to ensure that only his bloodline would benefit from his hard work.
