'Van der Valk' Delivers a Cure for Cancer & an Open Ending for Season 4

It's been a hard road on Van der Valk this season trying to get Hendrik to go to a doctor and get an official medical test to confirm his cancer diagnosis and come up with a treatment plan. Fighting with a friend when you know they are being stubborn against their own best interest is a universal experience; fear drives people to do a lot of weird things. However! It is not a universal experience to get that friend blackout drunk and then use workplace (in this case, police) resources to give them medical tests against their will. Piet Van der Valk would probably be offended to be lumped in with that crowd, AND YET. His hijinx this week went beyond the pale, even for him.

Piet decided to take matters into his own hands in the Season 4 finale episode by plying Hendrik with booze until he passed out and then wheeled him out to an ambulance where Julia and Lena were waiting. They started drawing blood when Hendrik officially woke up, rightfully freaked out, and ran off. Jules did at least admit that what they were doing was a crime and could cost them all their jobs, but shockingly, so many people went along with this ridiculous and violating plan*.

(*No time to dwell on it or to make sure Hendrik didn't sue all of them because there was still a double homicide to solve. Is that an American worry?)
