Tim and Erik haven't studied. Cheating might be an option, but it requires some effort. Erik needs to poop. Frederique is stressed because her rabbit was taken away.

Is Erik's flirting with Ms. Spek mutual? How does Viktor handle the new student, Lars? Can Tim finish Armani's homework in time and make it to his appointment with Marietje? In any case, math teacher Barteljaap gets destroyed.

Tim, Erik, and Tim's blue balls have to do a task for Hulst. This increases tensions between Tim and Marietje, who is also about to explode. Mr. Boom tries to explain to Viktor that Lars is not a monkey. Barteljaap reminisces about his youth, where he was also destroyed, of course.

Parent-teacher night, not fun for anyone. Tim and Erik need to come up with something so their parents don't find out about their bad grades. Lars' parents visit Viktor, and for Barteljaap, there's finally a tiny glimmer of light at the end of that long, pitch-dark tunnel.

The long and tough week is nearly over. Tim did abominably on the English test. Erik has a great plan for surviving the rest of the year, but can, may, and should Tim go along with it? Has Viktor learned anything this week? Can Barteljaap be destroyed even more?
