My gut says that since the swamp has been cleared, the rest are now doing business with regular companies, like your dad's company.

Dont overwhelm your dad with all the redpills if he hasnt been redpilled already. However, keep an eye on him and take interest in what kind of deals he is doing. Any deal where he has to stick his neck out is a cause for alarm.

Parties also worrisome. I would say he should ditch the parties to be safe, at least until he can know their motives better.
