Four friends decide that they're going to fight over who gets to eat the blood of the vampire first. They all agree that one of them is going to get the blood first, even though they don't know who that vampire is yet. This is a big deal, because it's the first time we've ever seen four friends fight over a single thing. It's kind of like a lottery, except instead of picking a random number, they have to pick the most random number of people they can think of.
