I hate the sight of blood. I'm perfectly fine with pictures of it, but seeing actual blood... well, let's just say I've had some "incidents" in the past and leave it at that, shall we? Anyway, I decided this would be an interesting character trait for Preston. Also, this marks the first major bit of major continuity in the comic; I've reused particular elements (such as that pesky vulture...), but none of them have been contributing to a sweeping storyline.
I have a few ideas for the story, but I think I'll concentrate on joke-a-day while placing little elements here and there for the next several weeks. I'm really excited about some of the things I've come up with, and David couldn't stop laughing at one of the ways I was reusing a tiny detail from the story later on at least once.
