Everyone in Biology notices how Edward and Bella walk into class together, and how they're now friendly with each other instead of hostile.
In Gym class, Mike tells Bella that he doesn't approve of her and Edward as a couple, claiming, "He looks at you like...like you're something to eat" (11.27).
As Edward drives Bella home, Bella asks why she can't watch him hunt sometime. Edward is horrified by the mere idea of her being around while he's hunting:
"When we hunt," he spoke slowly, unwillingly, "we give ourselves over to our senses...govern less with our minds. Especially our sense of smell. If you were anywhere near me when I lost control in that way..." He shook his head, still gazing morosely at the heavy clouds. (11.74)
The next morning after Charlie leaves for work, Bella finds Edward in the driveway, waiting to take her to school. During the ride, he peppers her with questions: "What's your favorite color today?" (11.111), "What music is in your CD player right now?" (11.117), etc.
During lunch, Edward continues with his interrogation, and then again on drive home from school, up until Charlie is just about to pull into the driveway.
As Edward is leaving, Jacob and Billy Black pull up. Bella is nervous:
Billy still stared at me with intense, anxious eyes. I groaned internally. Had Billy recognized Edward so easily? Could he really believe the impossible [vampire] legends his son scoffed at? (11.164)
