Jay

Jay Merrick is the main protagonist of the Marble Hornets ARG and was the central point of view in MH for the majority of the series until he was fatally wounded via gunshot by Alex during Entry #49. Although he was teleported away by the Keeper after being shot, his fate wasn't revealed until his body was discovered by Tim in Entry #53, confirming his death.

Jay was a very determined individual who seemed to give out a great deal of effort into figuring out what was going on, with repeated ventures into areas he had seen The Keeper in before, alone. He also seemed rather oblivious and slightly unintelligent at first, but as time went on, he learned as seen from the beginning when sharing his location to his audience about going to the red tower, and then in later entries as he continues to change locations without telling anybody where he was going. The overall growth of Jay's character is paced but quickly becomes noticeable as time through Marble Hornets progresses. Like Alex, he videotaped himself constantly, although this was more to keep his thoughts intact as well as keep a record of his accounts due to many different lapses of memory. He did show coughing fits, lapses in time, amnesia, and many odd symptoms assumed to be prolonged exposure to The Keeper.
