The vampires seem to have broken an age-old rule, crossing into werewolf territory in search of Victoria. Jacob, determined to set the vamps straight (and embarrass Edward in front of Bella) shows up at Bella and Edward's high school, for what appears to be a confrontation of rivals; Bella's friends, unaware of the supernatural war brewing around them, simply think the guys are fighting over Bella, and comically place bets on who will win the showdown.
