Elizabeth read my anguish in my countenance, and kindly taking my hand, said, “My dearest friend, you must calm yourself. These events have affected me, God knows how deeply; but I am not so wretched as you are. There is an expression of despair, and sometimes of revenge, in your countenance that makes me tremble. Dear Victor, banish these dark passions. Remember the friends around you, who centre all their hopes in you. Have we lost the power of rendering you happy? Ah! While we love, while we are true to each other, here in this land of peace and beauty, your native country, we may reap every tranquil blessing – what can disturb our peace?”

– Mary Shelley

Frankenstein, Chapter 9. Elizabeth Lavenza urges Victor Frankenstein to overcome his dark passions and enjoy the love they share.
