Grandma Bjanka flees to the Živkovic family's place to stay after a general extermination of her building, so Blaž is forced to seek temporary accommodation with Špiro. However, Špiro does not stand still: he sets up a "double date" for Blaž and himself with "two bad girls". However, Maja is convinced that Blaž's "girl" was recently a man, so she puts a bug in Blaž's ear, which Blaž will have a hard time resisting, and in the process jeopardizes Špiro's "physics class".
