During a press conference, Novák said that the Ukrainian and Czech performers had to overcome a lot of barriers after their initial meeting -- cultural, linguistic (as they didn't have a shared language, so they communicated in a mix of English, Czech, and Russian), even a food one. In the show, a touching scene speaks about the discovery that the Czech Republic and Ukraine share the tradition of welcoming guests with bread and salt, which leads to a conversation on similarities between the countries.
