The circus folk leave. Vasek's parents – Mícha and Háta – arrive, with Kecal. Vašek tells them that he no longer wants to marry Mařenka, having learned her true nature from a beautiful, strange girl. They are horrified ("He does not want her – what has happened?"). Vašek runs off, and moments later Mařenka arrives with her parents. She has just learned of Jeník's deal with Kecal, and a lively ensemble ("No, no, I don't believe it") ensues. Matters are further complicated when Vašek returns, recognises Mařenka as his "strange girl", and says that he will happily marry her. In the sextet which follows ("Make your mind up, Mařenka"), Mařenka is urged to think things over. They all depart, leaving her alone.
