Message, or M3SS4G3, is a video found by Corrupt Secrets on a DVD.

Transcript
The Entire video is of an unknown figure standing a room, with a distorted version of Vision's profile picture flickering on his chest area. Here is an interpretation of the dialogue:

''You still think there is a way out of this.You are wrong. You made your choice many years ago. The time of the cleansing is near/here. You must be ready before the Master (unintelligible). One close to the other calls me a liar. They are right. But I am not a liar in this realm. I am a messenger making way in the shadows. If you do not listen, I will have to end this pitiful attempt. Shame on you for your decision, Choices. You never learn, any of you. Humans are weak.''

Speculation
This scene bears a resemblance to Choices' Profile picture, which leads me to think that this was also filmed in Answered's room. The meaning of this is uncertain.

The figure is suspected to be Vision due to the image on his chest.

The Master the figure refers to could be the Guardian, the Slender Man, or even the Tall One.

The one close to the other could mean a person who has contacted our reality but is from a different one.
