In one of the early scenes, Boma is not wearing his reading glasses. By default he does not have his glasses. Excluding the times he wears them and takes them off, this is a rare occurrence. He says his glasses are at the optician. In Het geld of het veld (1990) he goes an entire scene without his glasses in his office as well. They are around his neck then.
The second time in the fourth season that Pascale (Danni Heylen) looks dirty after an accident. The previous time was in De motorfiets (1993) when Pascale fell in dirt in a crash with Bieke's motorcycle as Bieke drove her somewhere.
