Haha, that's alright, at first when I created the two of them, I was more of an Ash fan, but as the story progressed, I became more so a fan of Luke. That wasn't the main reason why I killed Ash off, actually it had nothing to do with that, it just left more options for me with the sequel.
Thanks for the comment on the first one though, and to be honest, when I first saw that I had a story comment, I thought it was "Lilies", and I was like, WTF?! Hahaha :)
