When's the coub?

A man with curly hair in a light jacket rests his chin on his hand, looking pensive, as Russian text appears on screen asking "Когда будет следующий куб?" (When will the next cube be?). The scene cuts to a man with a mustache in a grey sweater sitting at a table, who responds with the text "Скоро, не скоро, или никогда" (Soon, not soon, or never), followed by "Скорее никогда" (More likely never), as he remains seated and looks forward.
