Mortality Quotes in Eclipse

How we cite our quotes: (chapter.paragraph)

Quote #4

Jacob was still warm, comparatively human. Mortal. (5.132)

Bella relates being warm with being human, or being mortal. That's why vampires are cold, because they're immortal. What other characteristics of warm and cold do we find in Eclipse?

Quote #5

Angela's easy human dramas were oddly reassuring. It was nice to know that life was normal somewhere. (6.20)

Bella seems to believe that mortals are more prone to exaggerate life's obstacles. How could human drama and mortality be related?

Quote #6

[Bella to Jacob:] "I know it's silly, but their hearts are in the right place." "Their hearts!" he scoffed. (6.244)

Obviously, Bella is talking about the Cullen family's "mental" heart, but Jacob seems to believe that the absence of a physical heart negates the presence of a mental heart. Does he have a point?
