it's kinda hard to watch em over and over.. like we're sposed too.. considering i've already seen what happens.. its not a "its boring" thing, its just that seeing them all ":D!!!!!!!!!" is weird after the murders o.0 kinda like school days
new story arc, just means that every 4 episodes when everyone dies, they show a different way that everything could have ended. (different people going crazy, new people dying etc.)
