In the penultimate entry, Tim finally confronts Alex at Benedict Hall. During their fight, it's confirmed by Alex that the entire cast of Marble Hornets is indeed dead, including Amy and Brian, because he believes that killing everyone involved with the film is the only way to stop the Operator from spreading his disease to other people. This is learned only after Tim mortally wounds him. At the end of the entry, it's left ambiguous as to whether Tim made it out alive, but at the beginning of the final entry (#87), he's shown to have survived, along with Jessica, who appears briefly alongside Tim as they briefly update each other on their physical statuses and mental well-being. At this point, Jay has been long dead (I can't remember precisely how, when, or why), but Tim lies about him being alive to Jessica before they depart. The final shot is of Tim driving off, and it stops as soon as Tim reaches a fork in the road.

Virtually no questions regarding the Operator were answered. A lot of people think they pulled a Lost, but frankly, I don't really want to know anything about the Operator. Part of what makes him a fearsome entity is indeed the fact that he is so mysterious, and having an explanation for all his motives and whereabouts would not only spoil that, it also wouldn't make a lick of sense. How exactly would you be able to explain something like the Operator anyway? There is nothing they could have written that would have satisfied anybody, and that's precisely why I'm satisfied with such an ambiguous ending.
