Entering the garden together, Camille and Valencienne are no longer concealing their passion for each other. Camille entices Valencienne to enter the pavilion in the garden with him. Njegus, arriving for a meeting in the pavilion with the Baron and Danilo, sees what happens and goes to the pavilion door to peep though the keyhole. Baron Zeta and Danilo arrive, and, seeing Njegus at the door, they go to join him, as they think that Njegus is opening the door. Njegus quickly locks the door, and, when Baron Zeta and Danilo find the door is locked, they demand he unlock the door for them. Njegus refuses to do so. As the Baron and Danilo discuss what to do with Njegus, he breaks away from them and looks around desperately for help. Seeing Hanna, who has just arrived in the area, Njegus explains the situation to her and asks her to change places with Valencienne in the pavilion. Hanna agrees to do so.
