Continuity mistake: Lee makes a typo in the letter, spelling the word 'knowledge' incorrectly and Edward circles the end of the word. However as she reads the same letter, we see the word 'illuminating' is the word which has been misspelt and now the whole word is circled. Also the word was surrounded by text when Edward circled it, but when Lee is reading it, the word is at the end of the sentence with no words following it.
E. Edward Grey: Why do you cut yourself, Lee?
Lee: I don't know.
E. Edward Grey: Is it that sometimes the pain inside has to come to the surface, and when you see evidence of the pain inside you finally know you're really here? Then, when you watch the wound heal, it's comforting... Isn't it?
Lee: I... That's a way to put it.
Lee: In one way or another I've always suffered. I didn't know why exactly. But I do know that I'm not so scared of suffering now. I feel more than I've ever felt and I've found someone to feel with. To play with. To love in a way that feels right for me. I hope he knows that I can see that he suffers too. And that I want to love him.
