Big Mistake (15)

Context
Big Mistake (15) was uploaded by Hollis Coogan on September 18th, 2020, and has a runtime of 0:35. Its description reads "Everyone is against you."

It is notably the first video uploaded after Anthony's takeover of the channel in If You've Been Watching the Videos on this Channel... (14), and appears to be a direct response to that video. It remained the only video from Hollis uploaded after Anthony's takeover until Run in Circles (18).

Content
The video consists of a black screen and flashing image fragments with text appearing on screen, the text seen in the video is as follows:

0:09 - "JUST TRY AND SILENCE ME"

0:20 - "JUST TRY AND SILENCE ME", the static filled words "FIND ME" fade in over the words "SILENCE ME", creating the phrase "JUST TRY AND FIND ME"

Analysis
The flashing image fragments were isolated and stitched together by Reddit user u/wasala2 to reveal a picture of Hollis, confirming Anthony's theory that the man in his house was indeed Hollis.
