Over the weekend, Bella decides to go with Mike, Eric, Tyler, Jessica, and some other friends from school to a beach in La Push. She meets everyone at Newton's Olympic Outfitters, Mike's father's store, and rides in Mike's car to the beach.
At the beach, they have a bonfire and meet up with some guys that live on the La Push Indian reservation. One of them is Jacob Black – Bella's dad Charlie is a friend of Jacob's dad Billy. In fact, Bella's truck used to be Billy's.
A girl named Lauren makes an annoying comment about the Cullens. "The Cullens don't come here" (6.81), one of Jacob's friends says cryptically.
Bella is determined to find out exactly what he meant. She asks Jacob to come on a walk with her, and flirts up a storm, hoping to get him to tell her more about the Cullens. Trying to impress her, Jacob tells Bella a Quileute (that's Jacob's tribe) story about "the cold ones":
"The cold ones are traditionally [the Quileutes'] enemies. But this pack [of cold ones] that came to our territory during my great-grandfather's time was different. They didn't hunt the way others of their kind did – they weren't supposed to be dangerous to the tribe. So my great-grandfather made a truce with them. If they would promise to stay off our lands, we wouldn't expose them to the pale-faces."
[…]I tried to keep my tone casual. "So how does it fit in with the Cullens? Are they like the cold ones your great-grandfather met?
"No." [Jacob] paused dramatically. "They are the same ones." (6.117, 122-123)
So what are these cold ones? Jacob explains, "Blood drinkers […]. Your people call them vampires" (6.128).
Bella feels guilty for using Jacob, but she thinks he's a nice guy.
