Edward wakes up from his unrestful sleep and sees that Marguerite is still not awake. He wants to wake her up but doesn't act on it, feeling an odd dread in his chest. He doesn't want to see her empty eyes anymore. It's almost torturing.
He at the very least considered Marguerite a friend, but his friend was destroyed because of him. How could he possibly feel okay?
Yet, he knows that there isn't much he can do.
He approaches her in his cat form and leans in to her ear. He wants to whisper the secret words that could instantly heal her while he knows she is unconscious. This way he can trick his mind and his heart into thinking he did it, he saved her.
But it's all a fallacy. A stupid idea and a vain act. Though that notion doesn't stop him from trying.
"Marguerite, I know you grieve Jurian."
Silence. The steady beating of her heart and her even breathing almost seems to create a serene melody.
