如果他成功的打破了吸血鬼的诅咒，那将会让狼人永远处在他们的诅咒中，狼人们将会在每个月月圆之夜经受变身折磨。

If he succeeds in breaking the curse, it'll bind the werewolves to their curse forever, and they'll continue to endure painful transformations every month.

要破除吸血鬼所受的诅咒就要进行祭祀仪式——仪式将会在一个月圆之夜进行，届时将会需要吸血鬼的死亡、巫师和狼人当然还有Elena

Klaus' arrival sets events in motion for the sacrifice ritual -- which requires the demise of vampire, a witch, a werewolf, and of course, Elena -- on the night of the full moon.
