So i heard that Buffy died and her mate brought her back then she jumped in that portal and dies then willow brings her back does she die again after that and how long did willow wait to bring her bk?

Answer 1

Buffy has died twice, she died in series one by the master biting her neck an then throwing her into the water and she drowned,but Xander finds her and brings her back.

Buffy also dies in series 5, because her little sister Dawn is called THE KEY. !
And if Dawn bleeds it opens up a hell dimension,and only the Summers blood can stop it, Dawn was going to jump in the portal when Buffy stops her,Buffy decides to save the world and her sister Dawn,by jumping into the portal. This episode is called The Gift series 5. This episode was supposed to be one of the last ever episodes. !

Willow and the rest of the Scooby gang try an bring Buffy back from the dead in series 6: Bargaining part one and two, because they all thought she was in hell. It takes a while before Buffy rises though as Willow does the spell and a lot of Demons think that Buffy is a robot as there was Buffy Bot replacing the real Buffy for the start of series 6. As the demons chase Buffy Bot all over town an end up hurting the Robot she has to come to Willow so she can be fixed. The demons follow the Robot into the garden were Willow is trying to do the spell,and one of the motorbikes runs over the bottle of blood that would of helped Buffy to be brought back and that is were the spell finishes because of the Demons. !

After Xander tells Willow that the spell did not work, we go under ground to see Buffy rising from the dead,as all of the gang left her because they thought the spell did not work, Buffy has to dig her way out of her own grave.

Im telling you a whole story here! watch it on YouTube. The gift: series 5. Bargaining : series 6.
