basicly what happend was they all went to fight glory and resc( i bet you didnt see that one coming). buffy beats the craps of glory with this real big hammer, then giles kills glory when she goes back to being that o.r. dude. glory gets cut by some old guy, i didnt know who he was. buffy kills him. the universes start to mold together, so since buffy and dawn are sisters, they have the same blood cause dawn was made from buffy. so if either one of them dies, the universes are saved. so buffy kills her self and every one cries and it ends.
