How we cite our quotes:
"You can't really believe that I would give in so easily," [Edward] said with a sour edge to his mocking tone.
[Bella:] "A girl can dream."
His eyebrows rose. "Is that what you dream about? Being a monster?"
"Not exactly," I said, frowning at the word choice. Monster, indeed. "Mostly I dream about being with you forever." (Epilogue.199-202)
Bella has decided that she wants to be with Edward forever, and the only way to do that is by becoming a vampire. Edward, however, has had decades to think about human life and vampirism, and he is absolutely against Bella becoming a "monster."
"Did you ever think that maybe my number was up the first time, with the van, and that you've been interfering with fate?" I speculated, distracting myself. [...]
"That wasn't the first time," [Edward] said, and his voice was hard to hear. I stared at him in amazement, but he was looking down. "Your number was up the first time I met you." (8.213, 214)
Bella seems to think that her life isn't only influenced by choices, but also by fate. Here she implies that she might have been "destined" to be killed by Tyler's van, and every minute she continues to live is just bonus time. Edward, however, worries that his choice to remain in her life will eventually mean her death. At the end of the novel, Edward contemplates leaving Bella because that might be "what's best" (24.273) for her.
[Edward to Bella:] "You were right – I'm definitely fighting fate trying to keep you alive." (9.177)
Is Edward is fighting fate? Does Bella simply have a propensity for trouble, or do the choices she and Edward make put her in danger? If she does have a natural propensity for trouble, is Edward's falling in love with her another example of trouble, similar to Tyler's van skidding toward her?
