How did Buffy beat The First? I know she got wounded in the battle, but I don't remember The First dying. Did it die/get defeated when Spike blew up the Hellmouth?
U... What was the scythe? Sorry... I only watched that episode once and that was a few weeks ago.
Sorry, I deleted my コメント because I realized it would be better as an answer. The Scythe was the weapon Buffy used to kill the UberVamps - it's also the same weapon Fray uses in her series, and Buffy is seen with it on the cover of the season 8 comics. It's like this axe thing with a super sturdy extra pointy stake on the end.
The First just can't be killed 'cos it's evil in its primeval form and has no consistency on its own, but only in that of the persons it possesses (e.g. Caleb) または influences (e.g. Spike, Andrew). The First's plan in Season 7 was to rise an army of UberVamps beneath the Hellmouth and unleash it through its シール under Sunnydale's High to take over the world. Buffy and the Potentials (later become Slayers on their own) defeat that army in "Chosen" and Spike closes the Hellmouth once and for all, sacrificing himself for Buffy and mankind. によって the way, I suggest あなた to watch S7 in its entirety, 'cos it's really worth viewing (although not being the best season of the serie).
