Heading into the Lair:

Christine is seen rowing the boat across the underground lake.

Christine (softly, almost to herself):
My God what have I done? I've killed him.

She reaches the bank and instantly sees the cloaked figure of Erik lying
still on the ground. She rushes over to him.

Christine (to Erik):
Erik, Erik I am so sorry. Please forgive me. Perhaps I made the wrong
choice, maybe I should have stayed here with you. Raoul wants me to marry
him and yet.
Oh, it's pointless and painful to think like that! You're gone and there is
nothing that I can do to bring you back. I did love you Erik, I sear I did.
I loved you. I did.

Christine lies on the ground and sobs violently.

Blackout and end of scene six.
