Many things were omitted from the skit, of course, there's only so much that will fit in just one hour, but Brandon did make quite a number of dives to the floor while making fake death noises. And yes, it was hilarious. For example, the Asmodean death scene was preceded by a "lesson in magic" where Brandon pulled out some Magic: The Gathering trading cards and started explaining a new combo to Jason Denzel of dragonmount.com, who played Rand. Jason then asked him about a Black Lotus Asmodean supposedly owed him and Brandon went looking for it, leading to the sudden "You!"+death. Sadly, no one played the role of his killer (Brandon just looked behind the projector screen) so we can't speculate about the possible meaning of that person playing some other role (or not playing any of the other roles included) with regard to Asmodean's killer.
Hmm, I'd guess Lan for the spoiler. Unless something unexpected turns up, all he has to do is get there and watch an army materialize around him on the way.
