Alex was the director for the student film Marble Hornets. Early on, the series focuses on the tapes that Alex gave Jay and the mental breakdown that occurs during the time he worked on the film, with Jay adding comments and notes about the content. However, even though the videos have shifted to centring on Jay and his dilemmas, Alex is still a very prominent character.Originally described as being enthusiastic, the videos from the Marble Hornets filming in 2006 display his descent into madness, paranoia, anger and other forms of psychosis.After being stalked by the Operator, it is shown that he is very violent, incapacitating several of his friends in various videos. The greatest explanation of Alex's personality likely comes during Entry #86, where he sees himself as a force of good. Apparently having discovered The Operator's memetic spread, he takes it upon himself to kill everyone who has come into contact with The Operator, and save the planet. As Tim points out, however, The Operator is likely using Alex to spread further, as he has been causing more havoc than he had intended.
