The rest of the play sees Turai, Natasha, and Ivor (who is married and terrified of his wife finding out), assisted by the cabin steward and jack-of-all-trades Dvornichek, attempting to convince the suicidal Adam that what he heard was in fact a rehearsal for a new ending written by Ivor.
Eventually, Adam is convinced that the whole thing was a rehearsal, reconciled with Natasha, who proposes to him, and cured of his speech impediment.
