Isolation Quotes in Twilight
How we cite our quotes:
[Jessica to Bella:] "You Know, I've never seen Edward sit with anyone but his family before. That was weird." (6.7)
It's a novel action for Edward to sit with someone outside of his family. That's probably because none of the Cullens ever invited a human to their lunch table. Edward is now opening up to a human and ending his voluntary isolation.
[Bella to Edward:] "My mind doesn't work right? I'm a freak?" The words bothered me much more than they should – probably because his speculation hit home. I'd always suspected as much, and it embarrassed me to have it confirmed. (9.18)
Edward thinks himself strange because he can read minds, but Bella is the one who feels isolated because he can't hear her voice. Here, we have two people, who have previously felt lonely and isolated, coming together.
[Edward:] "Don't you see, Bella? It's one thing for me to make myself miserable, but a wholly other thing for you to be so involved." (9.157)
Edward considers exile before being with Bella – he would rather live a lonely life than put her at risk.
