TO

TO is the fourty-second video uploaded by novelty. It was uploaded on February 17, 2021 with the description, "U0VUIE1FIEZSRUU".

Description
The typical audio plays as the camera is viewing something unidentifiable due to the quality. The only thing that can be accurately observed is a square-shaped object seemingly just hanging there in front of novelty. Eventually we hear 3 loud knocks and a door opening. The camera moves slightly to the right, showing that there's a light source just off-camera.

Analysis

 * Decoding the description via base64 gives you the message, "SET ME FREE".
 * Novelty commented under the video, "betterment".
 * If the knocking came from another person, this would mark the first time a second character has been introduced into the story.
