Nothing says “diving deeper” better than climbing a hill!

Okay. Today’s installment makes less sense to me. First, how can Mark be staying late when last we saw, he was home with Cherry? Did I oversleep for a week? Second, who said this was a resort for the rich? It is supposed to be a retreat for STEM professionals. That could mean teachers, too. Third, when and how did Mark check into the financials of the residents? Fourth, Mark’s “faces” balloon in panel 2 fails to display the shipping owner and his assistant, who were present when Mark first showed up. Don’t they count, or did they check out immediately after Mark arrived? Fifth, why is Mark searching through the hills at night if the issue is financial? Does he expect to find a hidden workshop printing counterfeit thousand-dollar bills?

Any answers or explanations, other than Rivera must have been cuckoo or stoned?
