Pol, Bet's friend who has come to stay at the base, has chicken pox. Bet is vaccinated against the virus but not Mandi who, pretending to be immune, wants to avoid the puncture. Also the Edebits have a "virus" in the network spread by Spam. Bet is afraid of the dentist who is going to visit her so she asks the Edebits to manipulate her file but the Edebits do not listen to her and in the end Bet repents herself for having lied.
