Octaaf enjoys playing the drums, but his bossy mother hates those. She orders him to start practicing on grandpa's violin to become a famous virtuoso like him, although he lacks talent or desire. Gert helps out by inviting him over with his drums and suggesting to masquerade as Gert's cousin John. Alas Jeanine isn't that easily fooled and nobody can stand any of Ocataaf's 'music'.—KGF Vissers
