When Billy returns very late from an endless drinking night, he finds Betty studying anatomy, panicking she'll fail her partial exams again, in which case even her generous dad may cut off her obviously pointless study allowance. Charles-Victor is highly amused her loitering is finally getting punished, the others try to help her. Koen inspires Billy to pretend she suffers from agoraphobia- the ploy is believed, but works no wonders: an assistant will take the exam in her room. Jef fears Jeanne no longer loves him, making him jealous of his best friend, highly appreciated handyman Odilon. Billy has another bright idea: now Betty's exam is in the house, they can fit her with an earpiece. However, not all is as it appears...
