Žungul arrives to help him, thanks to a little cunning (he announced to the editor an article about the columns in front of the House of Flowers), but their "hanging out" with Slađan will end in a grotesque style, just like the episode in SKC, where Una and her friends meet some from the future stars of the new wave.
