A lot of ways to kill the vampires.
1.} Bella was cold so Edward built a fire and did not live.
2.} Bella found a stick and poked Edward with it but it did not work out like she thought it would so he died.
3.} Bella went to a pizza place and got a spicy, talking meat ball pizza, and gave a piece of it but he was killed.
4.} Rip their head off
5.} Bella kills herself
6.} He gets stepped on by a giant.
And if you have any ideas please tell me.
