Key Plot Points from The Twilight Saga: The Official Illustrated Guide
It's interesting that both Jacob and Edward are disturbed by Bella's reaction to seeing Jacob. Bella may have chosen Edward but it's incredibly obvious that she still has a strong connection to Jacob.
The blood has worked to make Bella stronger but that means the "fetus" is stronger too, now breaking Bella's rib.
This is the chapter where the digs really get started between Jacob and Rosalie. That's definitely one of the highlights of Breaking Dawn.
Seth is obviously comfortable with the Cullens, maybe a little more comfortable than Jacob would like. He gladly accepts the Cullens' offers of food and clothing. It's a little frustrating that Leah isn't willing to give when the Cullens are being so understanding and appreciative of the sacrifices that the wolf pack has made to defend them.
