Barn and Maggie find Quentin's Room. Suddenly they hear approaching footsteps--but it's only Professor Stokes, who followed them. He thinks Quentin died in this room. The trio find Amy hiding behind a curtain and unable to speak.
The I Ching! Stokes finds Quentin's set of I Ching wands and says he now knows a lot more about Quentin than he did a moment before. Barnabas looks apprehensive as he thinks about the I Ching, something beyond his ken.
We get the big "Turn of the Screw" scene: At Collinwood, Maggie comes down from the upstairs landing, closing the door behind her. She has obviously been searching for David and is trying to decide what to do now. She calls David’s name as she starts back up. Can you hear me? she calls. I know you’re in the house! I want to help you! Please make a sound, she begs him. On hearing nothing, she goes back down to the foyer, defeated. To her joy, David steps out onto the landing. Don’t come up here! he warns her. I’ve come to take you away, Maggie says. I know, he replies. Don’t you want to come with me? she asks. David nods. Quentin expresses his displeasure with a sudden thunderclap. Maggie calls out to him, I am not afraid of you! I am not going to let you keep David! Come to me, David, she implores him. Clearly paralyzed with fear, he wails, I want to, but I can’t! Maggie tells him, Then you can, you can if you try. Walk down the stairs and into my arms, she coaxes him. David looks back toward the closed landing door, then carefully backs away. Holding onto the railing, he starts to move toward Maggie, who tells him, You’ll never have to be afraid again! When he reaches the top of the stairs, the landing door slowly opens. He turns toward it fearfully and stops. Maggie calls out, Don’t stop now! Then she calls out defiantly, Quentin, you can’t have him! He is not yours to have! He is not like you, Quentin! I am going to make sure that he never will be! she vows passionately. After another thunderclap, Maggie faces the open landing door and tells Quentin resolutely, I’m not afraid of you! I’m not! You can’t change David! You have tried, and you have failed! Quentin, I love David, and I am going to take him away from you! Can you hear me? She tells David, I’m coming up to get you. David tries to tell her not to, but Maggie says scornfully, Quentin doesn’t have the courage to stop me. You don’t belong with him--you belong with your family and me. Now near the top of the stairs, Maggie reaches out her hand and tells David to come to her. David looks back one more time, then makes almost a flying leap into Maggie’s arms. She croons his name. Holding him tight, she tells him, There’s one more thing you have to do before you can leave--you must send Quentin away. I can’t! David protests, petrified, but Maggie insists, You’ll never be free otherwise. David turns to look at the landing door. It slams shut. David collapses into Maggie’s arms. Maggie misinterprets this as she croons with relief and gratitude, David! We’ve won! --but then to her horror David slumps unconscious on the stairs.
Stokes and Julia watch--Julia with great apprehension--as Barnabas throws the wands. He gets the 49th hexagram, the hexagram of change--and the one that almost everyone else in the show will get too. Julia is horrified as he mutters about "moving toward the coffin......"
