There is a chance that John van de Heuvel will be killed or at least give him a warning, because don't underestimate his knowledge of the Dutch underworld. He knows a lot. It isn't smart when they kill him but they don't give a shit.
And ofcourse Erik de Vlieger, he might be killed too because he created some enemies. Including one who doesn't care about him a all. And that enemie is the Justice Apartment. So we just have to wait, maybe it will be quit for some time.
