When I was reading Eclipse, at the part when Bella was choosing if she wanted to be with Edward or Jacob, I was really debating who she would choose.
So, when she was choosing, did Alices vision ever change?
If it didn't, then Edward would have always known that Bella would choose him. He wouldn't have had to have done the whole noble thing when he talked about stepping aside and letting Bella be with Jacob.
Sorry, i hope i explained it better this time. And sorry if it babbles a bit. It was just a question that . popped into my head and wanted answered.
So, I posted this before but don't think I explained it well enough. So i tried again.
