No, we know each other a bit, but there are plenty of things you don't know about me, and I'm sure the same goes for you as well, when it comes to what I know about you.
If it gets me killed, that'll be fine by me. I don't have much to live for. As for the other people, have I been the only one who's seen all these threats the past few weeks to kill off the entire city? You guys are acting like it's something new. A vampire army comes to town, and now people are dying? Wow! What a shock! Come on, Heather. This should have been expected from the very first day their group arrived here.
From what it sounds, it sounds like taking one of them down was already going to get people killed. Maybe they should have thought of that beforehand and taken all three down at the same time, so their army would collapse.
Would it really have been that difficult to have three separate Slayers/hunters trap all three of them, and try the method they came up with at the same time? Why did you try to fight them one by one, instead of waiting until you were ready to take all of them? You don't go headlong into a situation without knowing what you're getting yourself into. People do that with Silent Hill all the time and they get murdered.
