Lonleygirl15? Anyone else addicted? Did Bree get shot?

So the other day, I came across a video on YouTube. It was Christmas, to be excact. I watched this random Christmas video that came across my screen and thought "what the heck was that all about?" So I followed some of the tags. I watched more and more, and I was wrapped up in the story of Bree, aka Lonelygirl15. I know it's not real-life, but I love the drama and suspense! Anyone else? And..if you follow it...what are your theories on "The Unthinkable Happened?" Do you think there was a gunshot? If so, who do you think got shot?
