Helen understands how sad Peter's position is among these ignorant people, and she decides to marry him, for pity as much as for love. The father is no more satisfied with this match than he was with Nil's, and with death in his soul he is present at the dismemberment of his family. While Helen takes Peter, Nil goes off with Polya.
Those two figures will do just what's needed; Pyotr Meierhold. Only Nil's part, a wonderful part, must be made two or three times as long. You ought to end the play with it, to make it the leading part. Only do not contrast him with Pyotr and Tatyana, let him be by himself and them by themselves, all wonderful, splendid people independently of each other.
