Jacob meets up with Leah. She, of course, rejects Esme's food and clothes. Jacob eats his share, though, "not because it smelled irresistible away from the vampire burn, but to set a good example of self-sacrificing tolerance for Leah" (15.12).
Seth meets up with them after sweeping the perimeter. Everything is clear.
When Jacob decides to tell the Cullens to leave Forks in order to get Bella out of danger, Seth informs him that Bella broke another rib and that she depends on the medical access and blood supply at the Cullen house. She's also taken up contact with Charlie, assuring him that she's on the mend. Jacob is outraged by her lies, because he thinks she's giving Charlie false hopes.
When Jacob visits Bella at the house, she looks fragile and weak but is happy to see him. Rosalie and Jacob start bickering with each other again. When Edward asks her to bring Jacob some food, she serves it to him in a dog dish.
Jacob asks Bella if she has a due date for the little monster. She tells them that, according to Carlisle's calculations, she has about four days left. Jacob realizes that he's glad she's not leaving, and that her pull on him has become stronger. "Almost like it was related to her expanding belly" (15.124).
Bella tells Jacob that only with him being there, her family feels complete. "You're supposed to be part of my life – I can feel that, and so can you" (15.154). Jacob tells her he'd prefer that she didn't care about him at all, because he suffers being around her.
After Bella falls asleep, Jacob confronts Edward about the lies that Bella has been telling Charlie. Edward explains that she couldn't bear his anxiety about her condition. She hopes that there's a way for her to have a relationship with Charlie after her transformation and banks on Charlie drawing his own, false conclusions about her changed appearance. Jacob thinks they're all insane.
Edward then reveals to Jacob that the baby might not be the first of its kind, and that he sent Emmett and Jasper to research legends in South America that might help with the situation Bella is in.
Rosalie, however, points out that, according to the stories, no human females ever survived giving birth, because they lacked the knowledge and the medical and familial support the Cullens have been offering. She believes that they'll be able to deliver the baby safely.
Rosalie's continued emphasis on the baby's needs infuriates Jacob and he throws his dog dish at her head. The rest of the Cullens appear to be on his side in the matter.
When Bella wakes up, she's in pain because the baby's stretching. She compares its growth spurt with Jacob's once his werewolf gene was triggered. This causes Edward and Carlisle to discuss the similar genetics between the baby and Jacob, plus the fact that Alice can't see either of them. Jacob tries hard to deny any similarities between the baby and himself.
