I can't believe it myself, but I think we had it all wrong again. Given the fact that the killer was already inside the hall, the only possibility is that Scarlett was killed by... Sam. When Gwen and Sky got there, Katie was unlocking the doors, so she was on the outside. But when they got in, Sam was already there checking out the carnage. If Sam was already inside by the time they got in, he must have gotten in before they did. The only one who could've gotten in was the killer, so put two and two together and that must mean Sam is the killer. Guess I'll have to scratch one from my survivor list after all, my vote is for Sam.
