Victoria, James mate
Because he got Evil in New Moon and wanted to kill Bella but when he did Jacob and the wolf pack came out and killed Laurant to protect Bella:)
Laurant tries to kill Bella in Chapter 10 of New Moon.
Because Felix is trying to kill Bella and Edward is protecting Bella
bella want to kill felix while edward almost killed in new moon so bella felt that she can't kill anyone
Victoria
Laurant James and Victoria James trys to kill Bella in Twilight but the Cullens kill him Laurant trys to kill Bella in the middle of New Moon but the Jacob's pack kill him Vistoria trys to kill Bella in Eclpise but Edward kills her
Not really but I think she sent laurent to try to kill her in new moon and Victoria forms a army to kill Bella in Eclipse ! *Victoria wanted the privledge of killing Bella herself. She sent Laurent back to forkes to investigate the area to see if the Cullens were still protective of Bella and around her. Bella happened across Laurent while he was hunting and couldn't stop from killing Bella himself (regaurdless of how it would have angered Victoria) until he is distracted by the Wolves that come out to Bella's aid and chase him off and kill him. As far as Victoria herself she attempts many times to get close to Bella but always run into the wolves. Which in turn has her create the New born army to go after Bella to keep everyone busy, and hopefully gaurentee Bella's death.
Yes, they do.
For edward to come back
NO, of course not!!! Bella stops him from going into the sun!
There was sort of 3. Edward left Bella at beginning and at the end Edward wanted to kill himself and Bella had to go to save him. Also, the Volturi wanted to kill Bella after she saved Edward.
Yes, she "gets back with Edward" towards the end of New Moon.
