Overview: Arnout, Philippe and Ruben cross the sandy Kempen. At the Kleine Nete they pass a crab catching station. Arnout then visits some old friends in Geel: Rob and Eddy. Fifteen years ago he made a documentary about family nursing in Geel, in which the pair played a leading role. In the abbey of Tongerlo, Arnout comes face to face with Da Vinci's Last Supper, and in Westerlo he meets Prince Simon de Merode, who invites him to his castle. The prince's ancestors appear to have played an important role in the creation of Belgium.
