Hopefully that clears things up a bit, but feel free to discuss and - if you are so inclined - voice more doubts!
Thanks for answer, now this moment about Talana\Ygerna is more clear to me.
We just see the action, but hardly see real logic/events flow/thread behind it.
Yeah, like Damian who able to kill our Slayer many times, but he didn't. It is obvious the game is over in our first meeting Damian if thing goes like that, but some explanation in my opinion, works fine here. Like "he was in spiritual form, so he can't harm you directly" or something else.
