She’s lying. She’s trying to trick me with her desperate
imagination, her delusions. It won’t save her, nothing can save her now,
because I will never stop. Everything is ruined now, everything! And she is to
blame for it. She will suffer. She will bleed. She will die!

Yet, in this cocoon of mist, this hazy limbo where there is
no direction, where all I feel is rage, this monstrous rage, I can sense
something more. The machine, that infernal machine, so filled with his hopes;
that thing that tied him to us and this bloody mire of a place yet gave him
dreams of freedom—it is clawing at the earth, roaring with purpose, alive…

She is so weak, so delusional. I am relentless, and she must
succumb. I am death, the natural savagery, and she will not survive this. She can
hardly stand, little butterfly with broken wings, swaying in her poisoned weakness.
She could not have turned it on, awakened that hissing beast. Yet it moved,
disturbed from its slumber by…what? The impossible?

The image is monstrous, full of sorrow and accusation,
marred and broken. It is everything from which I tried to shield him. It is his
soul, his pure soul, so racked with guilt, so ashamed that he cannot even look
at me as I turn to face him. I can see him, the truth of him, see would we have
become. We had been dead a long time, he had said, but it is only now I
understand.

Oh Thomas, I loved you! You were the better part of me, the
sole reason for my living. I made myself endure the pain for you. I longed for
you, craved your passion and your sanity, your perfection in face of my
ugliness. And now…you bleed for me, brother, for I cannot stop. I am caged,
dying in my own bell jar. I thought I was the moth, dark and deadly and full of
silent secrets, but you always knew, didn’t you, that I was a butterfly once,
too.

Oh, that girl, that golden creature that drew you to her,
all sunshine and flowers! It was love; horrible, wicked love, and you chose
her, Thomas, why? She could see what you saw, was that it? She was the good
that I was denied, and I…I destroyed you. This is all you have left for me, the
regret and the madness…

He is free now. He is gone. My doing! My love and my
violence did this to him, to us. I cannot live without him. His eyes, his
haunting face…I cannot look any longer. Oh, Edith, the girl who sees ghosts,
who saw the goodness and the torment in my brother’s soul, can you see the depth
of my agony? I was once an innocent girl too, a sister who only wanted to love…
Please, I can only plead for some comprehension, some acknowledgment that it
was all for love, even now it is for love…one last punishment, and this one
deserved. Please, Edith, make this stop…
