How we cite our quotes:
[Carlisle to Edward:] "It's your decision, Edward, either way. I can't help you. I have to get this bleeding stopped here if you're going to be taking blood from her hand." (23.47)
Edward has a difficult decision to make: he can either let Bella transform into a vampire (which will naturally happen, since she's been bitten by James), or attempt to suck the venom out of her blood and save her human life. We know that Edward is determined for Bella to remain human, but we also know that he's terrified of coming near her blood, for fear of loosing control and killing her.
"Edward!" I screamed. I realized my eyes were closed again. I opened them, desperate to find his face. And I found him. Finally, I could see his perfect face, staring at me, twisted into a mask of indecision and pain. (23.49)
Edward's position is a tough one, and Bella sees that.
[Bella to Edward:] "Renée has always made choices that work for her – she'd want me to do the same. And Charlie's resilient, he's used to being on his own. I can't take care of them forever. I have my own life to live." (24.216)
Bella tries to convince Edward to turn her into a vampire. She explains that her parents have never considered her when making their life choices, and they'd want her to pursue what would make her happy. Do you buy this argument? Imagine Bella as a young vampire – would it be safe for her to be near her parents? Would she even remember her human past? Has she truly thought through the implications of her decision?
