Today is the day of the medical visit at school. In Eliot's imagination, the nurse who will examine the boys is none other than Diabolika, the same as in the comic strip he has just been reading. Danger! The demonic scientist absorbs the life force of children! The problem for Eliot is that he did not have time to read the end of the comic book and so he does not know how to get rid of this Diabolika.
