Four

Aidan, or Four, was a member of Holofernes up until May 19th, 2016, when his video 'i'm going to sleep now' was released. This video was designed to result in Four's expulsion from Holofernes, but it is thought he had attempted to leave beforehand.

In the video, Four warns viewers not to trust Five, as well as state that he isn't afraid of someone, likely X. Following this, he states he is going away for a long time, and won't likely be back, and closes with a common phrase used among members of Holofernes - Lights out.

Four's Facebook account was deactivated soon afterwards, as shown to solvers by Nine, who was his girlfriend. His current whereabouts are unknown.

On the 20th of May, Four's Skype account, holofernesfour, logged in to tell the winners of the 18th May Evaluation what their next moves were. This means that Aidan had either been replaced, or X was using his account.

The May 25th Evaluation confirmed that Four has indeed been replaced, as a new Four was a host of the evaluation.
